Wobbegong

Spotted wobbegongs rest flat and motionless on the cavern floor of Erscotts Hole, their extraordinary camouflage rendering them nearly invisible against the encrusted basalt. As ambush predators they rely entirely on concealment, erupting with explosive speed to engulf fish and crustaceans that venture within striking range, and the cave's still water and absence of strong current make it an ideal hunting environment for this sedentary species.
