Etymology: Chaenogaleus: chaeno-, from chaino (Gr.), gape, referring to “rictus as long as wide”; galeos, a small shark or dogfish per Aristotle (sometimes translated as weasel, hence the name Weasel Sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks1), but in this case probably an allusion to Hemigaleus, original genus of C. macrostoma. (See ETYFish);  macrostoma: macro-, from makros (Gr.), large or long; stoma (Gr.), mouth, referring to long, greatly arched mouth compared with Hemigaleus microstoma, its presumed congener at the time. (See ETYFish).

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Bronzy-grey above, white below when fresh, fading to greyish or greyish brown in preservation, dorsal fins often with dusky or black tips (Ref. 13567).

биология     глоссарий (например epibenthic)

A common inshore and offshore shark found on the continental and insular shelves (Ref. 13567). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 244). Viviparous (Ref. 50449). Caught irregularly by inshore gillnet fisheries and occasionally by small-scale longlining (Ref.58048). Probably taken by artisanal fisheries wherever it occurs (Ref. 13567). Utilized fresh for human consumption and by-products processed into fishmeal (Ref. 244).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Viviparous (with a yolk-sac placenta), with 4 young in a litter (Ref. 244). Size at birth at least 20 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).
