Port Jackson Shark
Scientific Name: Heterodontus portusjacksoni
Description: Often seen resting beneath reef ledges during the day, these small to medium-sized nocturnal sharks have a distinctive dark mark around the head, with a blunt snout and a low ridge over each eye.
The Port Jackson Shark has two triangular dorsal fins, each with a strong spine, and while otherwise harmless, should not be disturbed.
These sharks lay an unusual corkscrew like egg which is wedged between crevices in the reef.
Where to find: Subtidal Reefs
