Дефиниција: A taxon is Endangered when the best available evidence indicates that it meets any of the \r\ncriteria A to E for Endangered, and it is therefore considered to be facing a very high risk of extinction in the wild.
Дефиниција: A sheet of saline water separated from the open sea by sand or shingle banks. The sheet of water between an offshore reef, especially of coral and mainland. The sheet of water within a ring or horseshoe shaped atoll.
Дефиниција: An oceanic island, often having a characteristic ring-like shape surrounding a lagoon. Atolls are formed when coral reef grows around a volcanic island that later subsides into the ocean.
Дефиниција: Body/caudal fin propulsion, retaining eel-like body movements and exploiting interactions between the sidewash from an anterior median fin with the next posterior fin, increasing its effective angle of attack
Дефиниција: where individuals of the same species (conspecifics), maintain spatial proximity with one another over time with mechanisms of social attraction
