Orectolobiformes (Carpet sharks) >
Hemiscylliidae (Bamboo sharks)
Etymology: Hemiscyllium: hemi-, from hemisys (Gr.), half, presumably referring to similarity and/ or close affinity to Scyllium (=Scyliorhinus, now in Scyliorhinidae) and/or Chiloscyllium; skylion, Greek for dogfish or small shark (See ETYFish); ocellatum: Latin for eyed, referring to conspicuous white-ringed black ocellus on flanks above pectoral fins (See ETYFish).

البيئة
بحري مرتبطة بالشعاب; نطاق العمق 0 - 50 m (Ref. 54540). Tropical; 1°S - 34°S, 112°E - 163°E (Ref. 54540)
Western Pacific: New Guinea and northern Australia. Possibly occurring in Malaysia, Sumatra (Indonesia), and the Solomon Islands.
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm ?, range 60 - ? cm
Max length : 107 cm TL ذكر/ مختلط الجنس; (Ref. 247)
الأشواك الظهرية (المجموع) : 0; شوكة شرجية: 0. Caudal fin with a pronounced subterminal notch but without a ventral lobe (Ref. 13575). Lateral ocellus not surrounded by large spots; spots present on head in front and below eyes (Ref. 13575).
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
النضج | التكاثر | وضع البيض | بيض | الخصوبة | 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).
