Elasmobranchii (sharks and rays) > Orectolobiformes
(Carpet sharks) > Hemiscylliidae
Etymology: Hemiscyllium: Greek, hemi = half + Greek, skylla = a kind of shark (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 0 - 50 m (Ref. 54540). Tropical; 1°S - 34°S, 112°E - 163°E (Ref. 54540)
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 60 - ? cm
Max length : 107 cm TL male/unsexed; (Ref. 247)
Western Pacific: New Guinea and northern Australia. Possibly occurring in Malaysia, Sumatra (Indonesia), and the Solomon Islands.
Commonly found in shallow water of coral reefs (Ref. 6871). Often in tide pools (Ref. 13575). Feeds mainly on benthic invertebrates (Ref. 6871). Oviparous (Ref. 50449). Squirms when captured but cannot readily escape (Ref. 247). Survives well in aquariums (Ref. 6871). Has the ability to survive low oxygen conditions by switching of non-essential brain functions; apparently an adaption for hunting in tide-pools with low oxygen (Ref. 52022).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Prior to copulation, the male gets a good grasp of the female by by biting the body and even the gills (Ref. 49562, 51043).
