There is little information available on the biology of the bluespotted bamboo shark in the wild, with many details of its reproduction and other life history stages coming from captivity (1).
The mating season of the bluespotted bamboo shark takes place during December and January off the Taiwanese coast, although ovulation does not occur until March through to May, which may suggest that the female is able to store sperm (5). The female bluespotted bamboo shark is oviparous, laying eggs rather than giving birth to live young. The female will deposit two egg capsules on the sea floor every six to seven days during spring and summer. The maximum number of eggs per breeding season recorded for captive individuals is 26 (6), although wild individuals have been recorded laying between 4 and 14 eggs (5).
Bluespotted bamboo shark eggs hatch after an average of 110 to 135 days, and hatchlings may measure around 9.8 to 12.5 centimetres in length (2) (6). The young sharks grow rapidly over the first few months of life (6). Whilst longevity in the wild is unknown, captive bluespotted bamboo sharks have been found to live for up to 25 years (7).
The bluespotted bamboo shark is nocturnal, feeding at night upon small marine fish and crustaceans, and resting in reef crevices during the day (2). The bluespotted bamboo shark’s teeth are adapted for clutching soft-bodied prey and crushing hard prey (8).
