Tasselled wobbegong  (Eucrossorhinus dasypogon)

Biology

This primarily nocturnal shark (1) is a highly successful ambush predator (4). Like all wobbegongs, this species relies on camouflage and quick reflexes to catch prey, but its unusual ‘beard’ also helps by appearing as succulent morsels that attract prey close to the mouth (2). Motionless and disguised, the wobbegong waits in the reef for small fish, squid, cuttlefish or crabs to come within striking range (2) (3) (4), before moving rapidly to snatch its prey (4). Additionally, a flexible flattened body shape allows this species to squirm into enclosed spaces or manoeuvre in caves for the best hunting spot (2). This shark is thought to have a small home range with several retreats within the area (1).

Little is known about the biology of this species, although it is believed to be ovoviviparious, with live young born after hatching internally (1) (6). Litter sizes of up to 20 or more are produced (6).
