Orectolobidae (Carpet or nurse sharks)
Etymology: Orectolobus: orektos (Gr.), stretched out; lobus (L.), from lobos (Gr.), rounded projection or protuberance, referring to long nasal barbels of Squalus barbatus (=O. maculatus). (See ETYFish); wardi: In honor of Australian actor, musician and naturalist Charles Melbourne Ward (1903-1966), who collected holotype. (See ETYFish).

Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 63.0 cm TL mâle / non sexé; (Ref. 6871)
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 0; Épines anales 0; Rayons mous anaux: 0. Dark rounded saddles with light outlining widely spaced by dusky areas and with a few dark spots; saddles on head and trunk forming conspicuous eyespots (Ref. 13577). Caudal fin with its upper lobe hardly elevated above the body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13577).
Found on the continental shelf, commonly inshore (Ref. 247). Presumably feeds on bottom invertebrates and fishes, but diet still unrecorded (Ref. 13577, 43278). Probably ovoviviparous (Ref. 13577, 43278). Wobbegongs should be regarded as potentially dangerous because of their formidable teeth (Ref. 247, 13577).
