— 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.
