Bryozoan
* All bryozoans are colonial and most are marine.
* Some bryozoans encrust rocky surfaces, shells, or algae
  - form colonies through connection of individual units by stolons
* also have a U-shaped digestive tract.
* are almost entirely colony-forming animals
  - always colonial and almost always live in marine environments
* are colonial animals in the Phylum Bryozoa
  - animals, a collaborative group of specialized individuals, called zooids
  - microscopic animals that occur in both freshwater and seawater
  - colonial, filter-feeding organisms that are almost entirely marine
  - ecologically important in the Indian River Lagoon due to their feeding method
* are filter feeders, so prefer clear water to live in
  - feeding animals that form colonies or attach to rock surfaces
  - important in a kind of ecosystem way
  - microscopic individuals that form complex colonies
  - moderately tolerant of variations in environmental conditions
  - mostly marine, but some species are estuarine or freshwater
  - often twig or fan shaped
  - small colonial organisms that live in marine waters all around the earth
  - suspension feeding, sessile, marine or freshwater organisms
* band together into colonies to make it easier to capture food as it floats past.
* bear a striking resemblance to coral, but they are more closely related to brachiopods.
* can reproduce both sexually and asexually.
* dislike siltation and prefer clear water.
* grow colonies.
* have no special respiratory or excretory organs
  - several predators, including sea slugs, urchins, fish
* lace corals are beautiful living fossils.
* live in standing and flowing water.
* look a lot like corals, but are a different kind of marine animal.
* show several evolutionary trends.
* species diversity from the fossil record.
* use ciliated tentacles to filter suspended particles as in the photo at left.
+ Bryozoa, Ecology
  * Bryozoans are almost entirely colony-forming animals. Many millions of individuals can form one colony. The colonies range from millimeters to meters in size, but the individuals that make up the colonies are tiny, usually less than a millimeter long. In each colony, different individuals have different functions. There is only a single known solitary species, 'Monobryozoon ambulans', which does not form colonies

Coelenterate
* All coelenterates reproduce sexually.
* Many coelenterates are polytrophic feeders, able to derive nutrition in more than one way.
* Some coelenterates are jellyfish, corals, and sea anemones.
* are invertebrates.
* exhibit radial symmetry.
* incorporate many of the prototypical design elements found in higher animals.
* is an invertebrate

Comb jelly
* Comb jellies are a source of beauty, bioluminescent, and an improtant food source
  - able to regenerate any lost part, even an entire half of the body
  - all free swimming and never go through alternation of generations as jellyfish do
  - another member of the jellies group and are very similar to jellyfish
* Comb jellies are common in both warm and cold waters
  - residents of both nearshore and open sea habitats
  - quite beautiful organisms, existing in an array of ethereal shapes
  - the largest of all animals that utilize the beating of cilia for locomotion
  - come in many shapes and sizes , and so within the group there are many ways to feed
* Comb jellies have a much simpler reproductive process
  - no stinging cells, but instead use sticky mucous to catch their prey
  - live throughout the world's ocean, although most species prefer warmer water
  - use sticky adhesive to capture their food
* Some comb jelly has tentacles.

Beroe
* are conspicuous and easily seen from the surface.
* is comb jelly
