Elasmobranchii (sharks and rays) > Orectolobiformes
(Carpet sharks) > Hemiscylliidae
Etymology: Chiloscyllium: cheilos (Gr.), lip, referring to membranous and broad lower lip, presumably of C. plagiosum (proposed without a species); skylion, Greek for dogfish or small shark. (See ETYFish); hasseltii: In honor of Dutch physician and biologist Johan Coenraad van Hasselt (1797-1823), who explored the colonial Dutch East Indies with his friend Heinrich Kuhl in 1820. (See ETYFish).

Morphology | Morphometrics
soft rays: 0. Caudal fin with a pronounced subterminal notch but without a ventral lobe (Ref. 13575). Juveniles with dark grey-brown bands outlined in black, adults uniform medium- to dark-brown color, the black edgings being the last parts of the color pattern to disappear (Ref. 13575).
A common inshore bottom-dweller (Ref. 13575); on rock and coral reefs (Ref. 90102). Feeds on invertebrates (Ref. 13575). Oviparous (Ref. 50449). Utilized for human consumption (Ref. 13575). Minimum depth from Ref. 58018.
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).
