A powerful biotoxin produced by bacteria in certain marine dinoflagellates. Saxitoxin may be concentrated in the tissues of philtre 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.

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 specialised 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.
