Elasmobranchii (sharks and rays) > Orectolobiformes
(Carpet sharks) > Brachaeluridae
Etymology: Brachaelurus: brachys (Gr.), short, referring to short and stout body; aelurus, from ailouros (Gr.), cat, i.e., a short catshark. (See ETYFish); waddi: Name given on a painting (now lost) by British ornithologist John Latham (1740-1837), from which it was described; meaning unknown, possibly based on waddi or waddy, an Australian aboriginal name for a war club and a species of tree (Acacia peuce) endemic to central Australia. (See ETYFish).

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 122 cm TL male/unsexed; (Ref. 247); common length : 62.0 cm TL male/unsexed; (Ref. 247); common length :66 cm TL (female)
Usually found close inshore in tide pools (barely deep enough to keep it covered) and at the surf line, but sometimes deeper (Ref. 247). Prefers rocky shoreline areas and coral reefs (Ref. 247, 43278). Feeds on small reef invertebrates (Ref. 247), including crabs, shrimps, cuttlefish, squid and sea anemones (Ref. 43278), and small fishes (Ref. 247). Ovoviviparous (Ref. 43278, 50449). Thrives in an aquaria and capable of living out of water for a long time (Ref. 247).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). With 7 or 8 young in a litter (Ref. 247). Distinct pairing with embrace (Ref. 205).
