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); ornatus: Latin for adorned or decorated, presumably referring to its color pattern, described as yellowish with broad dark crossbands (the hinder ones encircling the tail), and two dorsal bands with “deeply fretted edges”, each enclosing a pairs of ocelli; name could also refer to the “tentacular fringe” around the head (See ETYFish).
Taxonomic Remarks
To be split. The subspecies O. o. halei is a valid species according to Huveneers 2006 (Ref. 58832).

Comprimento na primeira maturidade / Tamanho / Peso / Idade
Maturidade: Lm ?, range 94 - ? cm
Max length : 290 cm TL macho/indeterminado; (Ref. 6871)
Espinhos dorsais (total) : 0; Espinhos anais: 0. Back with light areas between dark saddles marked with dark, light-centered blotches and spots, not reticulated lines (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).
Body shape (shape guide): elongated.
A common bottom shark of inshore continental waters, on algal-covered rocky areas and coral reefs (Ref. 247). Nocturnal, resting on the bottom during the day and prowling on its reef habitat at night (Ref. 247). Presumably feeding on bottom invertebrates and fishes but diet unrecorded (Ref. 13577). Ovoviviparous (Ref. 50449). Attacks waders and fishers in tide pools (Ref. 247). Interest to fisheries limited; its skin very tough and attractively patterned and utilized for leather (Ref. 13577).
