A caudal fin with upper and lower lobes that are approximately equal in size; characteristic of most bony fishes.
Industry:Natural environment
A fibroepithelial tumor, probably caused by a herpes-type virus, found in juvenile, subadult, and adult sea turtles, causing them to be emaciated, weak, depressed, and anemic. Affected turtles may have flotation problems resulting from fibrous tumors in the lungs. Fibrous tumors are also found in visceral sites, such as liver, lung, kidney and gastrointestinal tract.
Industry:Natural environment
A lost or abandoned fishing net that drifts through the oceans posing a danger to fishes and other marine life.
Industry:Natural environment
A powerful biotoxin produced by bacteria in certain marine dinoflagellates. Saxitoxin may be concentrated in the tissues of filter feeding shellfish, and results in shellfish poisoning when ingested by humans; also known as mytilotoxin.
Industry:Natural environment
A species whose births exceed deaths in an area. Source species can provide individuals to populate other areas.
Industry:Natural environment
A vascularized extra-embryonic membrane of amniote embryos that forms as a narrow outgrowth of the hind portion of the gut. In birds and reptiles, it stores waste products of embryonic metabolism. The allantois fuses with the chorion to form the chorio-allantoic membrane in birds and reptiles, and a part of the placenta in mammals.
Industry:Natural environment
An informal taxonomic unit that includes coleomatic metazoans which possess a specialized filter-feeding organ, the lophophore. Almost all lophophorates are marine organisms and all are suspension feeders. Lophophorates are deutersotomes and are typically considered relatively closely related to chordates and echinoderms. There are three lophophorate phyla: Phoronida, Bryozoa and Brachiopoda.
