  टिप्पणी

Distribution: Atlantic, Indian and Pacific Oceans; mostly in deep or temperate waters and are valued as food fishes. Morphology: Body without scales; lateral line complete. Usually with pectoral fins. Branchiostegal rays 8-22. Vertebrae 105-225. Bahaviour: Occur in colonies in sand where they live individually in burrows from which they protrude to feed on plankton; also feeds on small fishes and crustaceans, primarily at night. Mating and spawning apparently takes place without any lengthy migration. Leptocephali (larvae) showed curling behavior which make them resemble gelatinous zooplankton, e.g. jellyfishes, in observations made at Osprey Reef, Coral Sea. This behavior could be an evolved response to threats by potential predators according to this study (Ref. 99222). Observations of the curling bahavior were captured in this video link: http://australianmuseum.net.au/Leptocephalus-curling-behavior
