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); galei: In honor of underwater photographer and shark enthusiast Jeffrey Gale, who successfully bid to help conserve this species at a charity auction, and who financially supported Conservation International’s efforts to preserve its habitat. (See ETYFish).

وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
This species of bamboo shark is distinguished by its unique combination of white lines/spots along the margin of the large, dark saddles on the back, scattered white spots particularly on the upper side, and a row of 7-8 well-defined, horizontally-ovate, dark spots on the lower side between the abdomen and caudal-fin base (Ref. 74956).
Occurs on shoreline fringing reefs or shallow patch reefs; observed at night at depths of 2-25 m (extreme depth from Ref. 114942), usually seen resting on the bottom, occasionally observed while slowly swimming or 'walking' over the bottom with the pectoral and pelvic fins. Probably sedentary during daylight hours, sheltering under rocky outcrops or tabular corals, typical for other family members (Ref. 74956).
