National Marine Fisheries Service, Circulars

The major responsibililies of the National Marine Fisheries Service (NMFS) are 10 monitor and assess the abundance and geographic distribution of

fishery resources, to understand and predict fluctuations in ihe quantity and distribution of these resources, and to establish levels for optimum use of the

resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforce- ment of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs, and mortgage

insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The NOAA Technical Report NMFS Circular series continues a series that has been in existence since 1941 . The Circulars are technical publications

of general interest intended to aid conservation and management. Publications that review in considerable detail and at a high technical level certain broad areas of research appear in this series. Technical papers originating in economics studies and from management investigations appear in the Circular

series.NOAA Technical Report NMFS Circulars are available free in limited numbers to governmental agencies, both Federal and State. They are also

available in exchange for other scientific and technical publications in Ihe marine sciences. Individual copies may be obtained (unless otherwise noted) from D822. User Services Branch. Environmental Science Information Center. NOAA, Rockville, MD 20852. Recent Circulars are:

FOREWORD

This NMFS Circular is part of the subseries "Marine Flora and Fauna of the Northeastern United Statesl' which consists of original, illustrated, modern manuals on the identification,

classification, and general biology of the estuarine and coastal marine plants and animals of the northeastern United Slates. The manuals are pubhshed at irregular intervals on as many taxa of the region as there are specialists available to collaborate in their preparation.

Geographic coverage of the "Marine Flora and Fauna of the Northeastern United States" is planned to include organisms from the headwaters of estuaries seaward to appro.ximately the 200 m

depth on the continental shelf from Maine to Virginia, but may vary somewhat with each major

taxon and the interests of collaborators. Whenever possible representative specimens dealt with in the manuals are deposited in the reference collections of major museums of the region. The "Marine Flora and Fauna of the Northeastern United States" is being prepared in col- laboration with systematic specialists in the United States and abroad. Each manual is based primarily on recent and ongoing revisionary systematic research and a fresh examination of the plants and

animals. Each major taxon, treated in a separate manual, includes an introduction, illustrated

glossary, uniform originally illustrated keys, annotated checklist with information when available on

distribution, habitat, life history, and related biology, references to the major literature of the group, and a systematic index. These manuals are intended for use by biology students, biologists, biological oceanographers, informed laymen, and others wishing to identify coastal organisms for this region. Often they can

serve as guides to additional information about species or groups. The manuals are an outgrowth of the widely used "Keys to Marine Invertebrates of the Woods

Hole Region;' edited by R. I. Smith in 1964, and produced under the auspices of the Systematics

Ecology Program, Marine Biological Laboratory, Woods Hole, Mass. After a sufficient number of manuals of related taxonomic groups have been published, the manuals will be revised, grouped, and

issued as special volumes, which will consist of compilations for phyla or groups of phyla.

ABSTRACT

An illuslraled key lo nearshore and shelf species includes 133 taxa. Seventy-nine genera are represented. In an annotated list, the distribution and ecology of each species are recorded within the area of Cape Hatteras lo Nova Scotia and out to a depth of 50 m on the continental shelf. The key is intended lo aid the nonspecialist in

identification of the species to be expected in the marshes, estuaries, littoral zone, bays, and inner parts of the

continental shelf.

INTRODUCTION

Foraminifera, an order within the class Sarcodina, are singlecelled animals characterized by having a rigid or flexible test, or

shell, and pseudopodia consisting of threads of protoplasm.

They primarily occupy marine waters, although a few species are able to tolerate brackish conditions and extend into the intertidal and estuarine zones. The floors of the outer continental shelf, the continental

slope, and the ocean basins (exclusive of the deepest parts of the oceans where calcareous materials are dissolved because of the undersaturation of calcium carbonate) are covered by vast deposits of the empty shells of planktonic Foraminifera. Planktonic Foraminifera, floating during life, shed their empty

shells onto the sea floor when the animals reproduce or die. This

deposit is known as Globigerma ooze in reference to one of the

principal genera involved. Planktonic Foraminifera are very rare over the inner parts of the continental shelf, and none are included in the present key. This key refers only to the bottom-dwelling or benthonic

species. Most of the species in the key are geographically wide

ranging. Some, such as Cibicides lobatulus and Miliammina

fusca, are recorded worldwide, within the limits of their respective environments. A few others, such as Hopkinsina atlantica and Pseudopolymorphina phaleropei, seem to be restricted to a

small part of the area studied. A few of the commoner ones, such as Elphidium banletti and Cribrostomoides jeffreysii, are

characteristic of Arctic and Subarctic regions. These seem not to extend much farther south than Cape Cod, Mass. For a few

others, such as Elphidium galvestonense and Poroeponides

lateralis. Cape Cod appears to be the northern limit. Very few of

the species in this area, other than those having worldwide

distributions, are found in waters south of Cape Hatteras, N.C.

Several reports describe and illustrate assemblages from

specific facies or areas of coastal regions along the northeastern United States. Among the most useful of these are Bailey (1851); Buzas (1965, 1968); Cushman (1944); Ellison and Nichols

(1970); Murray (1969); Parker (1948, 1952a, b); Parker and

Athearn (1959); Phleger and Walton (1950); Poag et al. (1980); Ronai (1955); Schafer and Sen Gupta (1%90; Schnitker (1971);

Scott and Medioli (1980); Shupack (1934); Tapley (1969); and

Todd and Low (1961). In addition, the following references provide useful records of distribution and details of morphology

pertaining to certain of the species of the northeastern United

States: Brady (1881c); Cushman (1918b, 1920, 1922a, 1923, 1929, 1930, 1931); Cushman and Ozawa (1930); Rhumbler

(1904); and Schultze (1854). MORPHOLOGY

The morphology of Foraminifera is diverse. In shape they range from a simple spherical or saclike chamber, with or without a single opening, to many-chambered forms in which

the chambers succeed one another in a variety of ways, such as

in a straight or coiled sequence. The coiling may be complicated

by differences in the plane of coiling and by consisting of a

single or a double row of chambers. In addition, these shapes

and structures can be found combined with any of several kinds of wall structure. Wails may be built of 1) various kinds of

foreign material gathered by the animal, or 2) calcium carbonate

extracted from seawater and then secreted by the animal, either

as solid layers or layers perforated by fine or coarse pores.

CLASSIFICATION

The shells of Foraminifera have been studied for some 150 yr,

initially as a hobby. Interest in them was greatly stimulated

shortly before 1920 when they began to be used in the search for petroleum. Because of their small size and abundance in well

cores, they served as convenient means of working out geologic

structures. Foraminifera continue to be important in geologic

investigations, particularly in biostratigraphy, paleoecology,

and paleobiology. Very few species of Foraminifera have been

cultured for study as living animals, and these studies reveal how

little has been learned thus far about life cycles and the natural

classification of this highly plastic group of animals. Many classification systems have been applied to the order. Loeblich and Tappan (1964), in addition to proposing the

classification currently in favor, summarized the earlier ones.

No attempt is made to classify systematically the taxa in this

key. Instead they are listed alphabetically for ease in locating any specific one.

TTiis key separates, as species, several forms that may not be

true biologic species but only phenotypes of a single species, i.e., variant forms that reflect the influence of environment upon the

genetic constitution of that species. The two species of Miliammina, the two species of Spiroplectammina, and the two species of Buccella may fall into this category of phenotypes. This key

separates, as species within different genera, some forms that may belong together as a single species. This feature is especially to be expected in the miliolids, a group that is mutable in a single

environment as well as highly variable under different envi- ronments. As an example, Quinqueloculina lata and Thloculina

brevidentata could probably be regarded as, respectively, quinqueloculine and triloculine forms of a single species. The solving of such questions is beyond the scope of this key, and it seems

convenient to have separate names by which to refer to these

distinct forms, whether or not they eventually prove to be

distinct species.

COLLECTION AND STUDY METHODS

In the intertidal zone, Foraminifera can be collected easily by

simple apparatus. Surface sediment can be collected in nested sieves—a 20-mesh screen above and 200-mesh screen below

(having openings of 0.850 and 0.0074 mm)—between which the

finer sand is caught and concentrated by washing in the ocean

water. Sediment clinging to the roots of marsh plants or scraped

off slime-coated cobbles can likewise be washed into and concentrated between the two nested sieves. A plastic syringe, such

as an oven baster, can be used to draw up material carefully, with a minimum disturbance of the surface sediment in or on

which Foraminifera live. In fine-grained sediments, a plastic

core-barrel liner can be forced several inches into the muddy

bottom and then withdrawn to remove an undisturbed segment

of sediment. In water too deep to use these means, Foraminifera

are generally collected by grab samples or corers. More precise

details about collecting and culturing have been described by

Arnold (1974). Foraminifera can be treated by the protein stain Rose Bengal

(Walton 1952) in order to determine which of the many

specimens in the collection were alive and which were merely

empty shells that remained after reproduction or death. To prepare a wet sample for study, the sample is washed by a

delicate stream of freshwater on a 200-mesh screen, then dried and separated by use of several nested screens into size fractions

for ease in examination. Each fraction is spread out thinly on a

tray and scanned, using a binocular microscope having

magnifications of about x 10- x 90 for the coarser to finer fractions. The specimens are picked out from among the sediment

grains by use of a moistened sable brush (sizes 000 to 00000 are

desirable) and transferred to a cardboard, glass, or plastic shde

that has been lightly coated with the water-soluble gum

tragacanth. By the use of the moistened brush, an individual specimen can be placed in the most advantageous position for

study, or moved into various positions for examination from all

aspects. BIOLOGY

The littoral species of Foraminifera are easily maintained alive

in small jars or bowls kept under cool and low light conditions.

and loosely covered to retard evaporation. It is not necessary to add food. The bowl is a self-contained unit in which the Foraminifera live on food materials in the sediment and original seawater in which they were collected. Freshwater should be added occasionally to compensate for evaporation.

The food of Foraminifera consists of diatoms, filamentous

algae, other microscopic algae, and probably also bacteria. Many species contain, within the protoplasm inside the chamber

walls, symbiotic algae which provide food for the Foraminifera

by photosynthesis. Those species that do not contain symbiotic

algae generally feed by ingestion of food outside the test. Some

capture their food from the surrounding seawater (filter feeding), others by grazing on the bottom sediment or on slime- covered shells, rocks, plant stems, or other supports that rise above the sea floor (deposit feeding).

Reproduction in Foraminifera has been studied in only a very few species. Asexual reproduction is accomplished by multiple

fission of the parent protoplasm, i.e., the breaking up of the nucleus into many parts so that each embryo receives a part of

the parent nucleus. This process leaves the parent test empty.

Reproduction normally involves alternation of an asexual and a

sexual generation, the two generations having certain dif- ferences in their test morphology. The individuals resulting from

the asexual phase generally have a larger initial chamber but a

smaller adult size than those resuhing from the sexual phase.

USE OF THE KEY

This key is designed as a finding key, not a classification key.

It therefore disregards a natural classification and, in a few

places, groups together genera that may have little phylogenetic

relationship to one another. Moreover, this key applies only to the species of the inshore waters along the northeastern coast of

the United States. Because of this restriction, some dichotomous

separations are made on combinations of features that elsewhere could not be combined.

In setting up the key we have tried to use easily recognizable

features and to explain, in diagrams and words, the differences between features that are not so easily recognizable.

The initial dichotomy between agglutinated and secreted tests may become a problem when the agglutination is very fine

grained, or when the secreted test is coarsely porous or its wall surface rugose. High magnifications, to x 90 or even more, are

useful in determining the true nature of the wall. Another

method for recognizing presence or absence of porosity is to touch the specimen with a lightly moistened brush and to watch

(under the microscope) the water as it either evaporates around

the imperforate test or sinks into the finely porous one.

Internal structures, such as tubes and septa, and chamber

arrangements can be observed by use of transmitted light, rather than the reflected light customarily used for study of

Foraminifera. To do this, the specimen must be transferred from the usual cardboard slide to a glass slide. Glycerine or

clarifying oils such as those used for petrographic study are

useful aids in observing internal features of Foraminifera

without the necessity of breaking the tests. The tests of some species are described as flexible or collapsible. This feature is demonstrable only when the animal is first collected and is still in seawater. As soon as it is dried, the test collapses into a flattened shape or shows concavities instead of

convexities over the empty chambers. Some of these collapsed

tests may reinflate when wetted. By observation of these sorts of

deformity, one can conclude that the test was flexible. At the many final dichotomies in this key, the separations are often made between species on the basis of imprecise features

that, if only one species is under study, are very difficult to

assess. Such imprecise features include slight differences in shape of test, length of septal bridges, or angle of sutures; small

differences in number of chambers; differences in degree of

inflation or compression, of roughness of wall, or of coarseness of pores; and differences of rigidity and flexibility. The subjective judgment required to choose between such nonspecific

separations can be aided by two specific factors: size of the specimen and its habitat. Size is included in the key descriptions

and habitat is included in the annotated list following the key.

valvelike tooth A broad plate that partly blocks the aperture

(see Fig. 14). vasiglobuline aperture Terminal aperture characterized by a

ring of small openings (see Fig. 19). wall Rigid or flexible material, porous or nonporous, that surrounds the living animal. whorl (or coil) A ring of chambers or, in a single-chambered

test, a complete revolution of the single chamber (see Figs. 1, 2a, 3a, 11a, b, 21, 22).

The Board established the format for the "Marine Flora and Fauna

of the Northeastern United States!' invites systematists to collaborate

in the preparation of manuals, reviews manuscripts, and advises the

Scientific Editor of the National Marine Fisheries Service. The authors acknowledge with sincere appreciation the helpful sug- gestions and gifts of specimens received from several of their colleagues during the course of compiling this key, chiefly Martin A.

Buzas, Stephen J. Culver, Robert L. Ellison, C. Wylie Poag, David B.

Scott, and Roland L. Wigley. The key was tried out by three student workers who had had little or no experience in dealing with forams.

Their frustrations and difficulties with the key enabled the authors to enlarge and improve it; the invaluable assistance of Merry

Cavanaugh, Angela Lanham, and Cathy McNair, all of the Smithsonian Institution, is gratefully acknowledged. The careful work of Ann Wallace of Chilmark, Mass., in doing the illustrations is also appreciated.

COORDINATING EDITOR'S COMMENTS

Publication of the "Marine Flora and Fauna of the Northeastern United States" is most timely in view of the growing universal emphasis on environmental work and the urgent need for more precise and

complete identification of coastal organisms than has been available.

It is mandatory, wherever possible, that organisms be identified accurately to species. Accurate scientific names unlock the great quantities of biological information stored in libraries, obviate duplication of research already done, and often make possible prediction of

attributes of organisms that have been inadequately studied. Ruth Todd began her studies of Foraminifera in 1940 as research

assistant to Joseph A. Cushman at the former Cushman Laboratory

for Foraminiferal Research in Sharon, Mass., and continued there

until 1950. Following the death of the Director of the Laboratory and

the consequent transfer of the Laboratory to the U.S. National Museum of Natural History in Washington, D.C., Ruth Todd continued her studies of Foraminifera at the National Museum as a member of the Paleontology and Stratigraphy Branch of the U.S.

Geological Survey. Following her retirement in 1973, she resumed her

collection and studies of the Foraminifera of the Atlantic coastal

regions. Doris Low began work on and studies of Foraminifera in 1951, working with Ruth Todd as a member of the Paleontology and

Stratigraphy Branch of the U.S. Geological Survey. With collections

made around the island of Martha's Vineyard during the summers of

1957 and 1958, she began intensive study of the Foraminifera of

coastal New England.

.0 Guidelines for Contributors

CONTENTS OF MANUSCRIPT

First page. Give the title (as concise^s possible) of the paper and the author's name, and footnote the author's

affiliation, mailing address, and ZIP code.

Contents. Contains the text headings and abbreviated

figure legends and table headings. Dots should follow each

entry and page numbers should be omitted.

Abstract. Not to e.xceed one double-spaced page. Footnotes and literature citations do not belong in the abstract.

Text. See also Form of the Manuscript below. Follow the

t/.S. Government Printing Office Style Manual, 1973 edition. Fish names, follow the American Fisheries Society

Special Publication No. 6, A List of Common and Scientific Names of Fishes from the United Stales and Canada, third

edition, 1970. Use short, brief, informative headings in place of "Materials and Methods!'

Text footnotes. Type on a separate sheet from the text. For

unpublished or some processed material, give author, year,

title of manuscript, number of pages, and where it is filed

agency and its location.

Personal communications. Cite name in text and footnote.

Cite in footnote: John J. Jones, Fishery Biologist, Scripps

Institution of Oceanography, La Jolla, CA 92037, pers. commun. 21 May 1977.

Figures. Should be self-explanatory, not requiring refer- ence to the text. All figures should be cited consecutively in the text and their placement, where first mentioned, indi- cated in the left-hand margin of the manuscript page. Photographs and line drawings should be of "professional" quality —clear and balanced, and can be reduced to 42 picas for page w idth or to 20 picas for a single-column width, but no more than 57 picas high. Photographs and line drawings

should be printed on glossy paper—sharply focused, good

contrast. Label each figure. DO NOT SEND original figures to the Scientific Editor; NMFS Scientific Publications Office

will request these if they are needed.

Tables. Each table should start on a separate page and

should be self-explanatory, not requiring reference to the

text. Headings should be short but amply descriptive. Use

only horizontal rules. Number table footnotes consecutively

across the page from left to right in Arabic numerals; and to avoid confusion with powers, place them to the left of the numerals. If the original tables are typed in our format and

are clean and legible, these tables will be reproduced as they

are. In the text all tables should be cited consecutively and

their placement, where first mentioned, indicated in the left- hand margin of the manuscript page.

Acknowledgments. Place at the end of text. Give credit only to those who gave exceptional contributions and not to those whose contributions are part of their normal duties.

Literature cited. In text as: Smith and Jones (1977) or (Smith and Jones 1977); if more than one author, list according to years (e.g.. Smith 1936; Jones et al. 1975; Doe 1977).

All papers referred to in the text should be listed alphabetically by the .senior author's surname under the heading

"Literature Cited"; only the author's surname and initials

are required in the author line. The author is responsible for

the accuracy of the literature citations. Abbreviations of names of periodicals and serials should conform to Biological Abstracts List of Serials with Title Abbreviations. For- mat, see recent SSRF or Circular.

Abbreviations and symbols. Common ones, such as mm,

m, g, ml, mg, °C (for Celsius), %, %o, etc., should be used. Abbreviate units of measures only when used with numerals;

periods are rarely used in these abbreviations. But periods

are used in et al., vs., e.g., i.e.. Wash. (WA is used only with ZIP code), etc. Abbreviations are acceptable in tables and

figures where there is lack of space.

Measurements. Should be given in metric units. Other

equivalent units may be given in parentheses.

FORM OF THE MANUSCRIPT

Original of the manuscript should be typed double-spaced on

white bond paper. Triple space above headings. Send good

duplicated copies of manuscript rather than carbon copies.

The sequence of the material should be:

of natural and technological changes in the environment and to monitor and predict the state of the solid Earth,

the oceans and their living resources, the atmosphere, and the space environment of the Earth

The major components of NOAA regularly produce

lion in the following kinds of publications:

arious types of scientific and technical informaPROFESSIONAL PAPERS — Important definitive research results, major techniques, and special investigations.

CONTRACT AND GRANT REPORTS — Reports

prepared by coniractors or grantees under NO.AA

sponsorship

ATLAS — Presentation of analyzed data generally

in the form of maps showing distribution of rainfall, chemical and physical conditions of oceans and at- mosphere, distribution of fishes and marine mammals, ionospheric conditions, etc.

TECHNICAL SERVICE PUBLICATIONS — Reports containing dala. observations, instructions, etc. A partial listing includes data serials: prediction and

outlook periodicals: technical manuals, training papers, planning reports, and information serials: and

miscellaneous technical publications. TECHNICAL REPORTS — Journal quality with

extensive details, mathematical developments, or data

listings. TECHNICAL MEMORANDUMS — Reports of
