Orectolobiformes (Carpet sharks) >
Brachaeluridae (Blind sharks)
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).
Eponymy: The original description does not explain the binomial. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 0 - 140 m (Ref. 6871). Tropical; 11°S - 36°S, 112°E - 143°E (Ref. 54288)
Southwest Pacific: confined to Australia, southern Queensland and New South Wales. Records from Western Australia and northern Territory need confirmation.
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)
Dorsal spines (total): 0; Anal spines: 0. Mostly with white spots on body (Ref. 13576). Caudal fin with its upper lobe at a low angle above body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13576).
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).
