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).

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).
