Sinbad (dog): Sinbad (c. 1937 – 30 December 1951) was a mixed-breed dog that was one of two animals to be classified as non-commissioned officers by an arm of the United States military, rather than property, prior to the enactment of regulations to prohibit such (the other being Sergeant Stubby USA, WWI) after being enlisted by the creative crew of USCGC "Campbell" .  Prior to and after an official retirement, Sinbad was assigned the rank of K9C or "Chief Dog" - equivalent to Chief Petty Officer.  At the time of the biography written by George Foley, no other member of the United States Coast Guard had yet been the subject of a published biography.

Kingfisher: Kingfishers or Alcedinidae are a family of small to medium-sized, brightly colored birds in the order Coraciiformes.  They have a cosmopolitan distribution, with most species found outside the Americas.  The family contains 114 species and is divided into three subfamilies: river kingfishers (Alcedininae), tree kingfishers (Halcyoninae), and water kingfishers (Cerylinae).  All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails.  Most species have bright plumage with only small differences between the sexes.  Most species are tropical in distribution, and a slight majority are found only in forests.  They consume a wide range of prey usually caught by swooping down from a perch.  While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates.  Like other members of their order, they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground.  Some kingfishers nest in arboreal termite nests.  A few species, principally insular forms, are threatened with extinction.  In Britain, the word "kingfisher" normally refers to the common kingfisher.

Panellus stipticus: Panellus stipticus, commonly known as the bitter oyster, the astringent panus, the luminescent panellus, or the stiptic fungus, is a species of fungus in the family Mycenaceae, and the type species of the genus "Panellus".  A common and widely distributed species, it is found in Asia, Australia, Europe, and North America, where it grows in groups or dense overlapping clusters on the logs, stumps, and trunks of deciduous trees, especially beech, oak, and birch.  During the development of the fruit bodies, the mushrooms start out as tiny white knobs, which, over a period of one to three months, develop into fan- or kidney-shaped caps that measure up to 3 cm broad.  The caps are orange-yellow to brownish, and attached to the decaying wood by short stubby stalks that are connected off-center or on the side of the caps.  The fungus was given its current scientific name in 1879, but has been known by many names since French mycologist Jean Bulliard first described it as "Agaricus stypticus" in 1783.  Molecular phylogenetic analysis revealed "P. stipticus" to have a close genetic relationship with members of the genus "Mycena".
