Where the name comes from

Orectolobus is “stretched lobe”, from orektós and lobós, for the branched fleshy fringes hanging all round its mouth and snout; maculatus gives the spots. Australians call it the wobbegong, a word of Aboriginal origin meaning roughly “shaggy beard”: it is the best of the three names.

Characteristics

  • 01

    The pattern of its back reproduces exactly the bottom it lies on.

  • 02

    The fringes round its mouth look like weed and draw prey in.

  • 03

    It hunts by lying still and lunging only at the last instant.

What sets it apart

It lies on the bottom all day and its livery is so effective that divers put a hand on it thinking it is rock: nearly every recorded bite in Australia happened that way, and the animal — which has long recurved teeth and jaws built not to let go — stays attached. It is not aggressive; it simply does not know it has been discovered until it is touched, and at that point it reacts as it would to a fish.
