Port Jackson Shark

Heterodontus portusjacksoni

Description:

The Port Jackson Shark has a squarish head with a small mouth and a crest above each eye. Two triangular dorsal fins are tipped with venomous spines. They are grey to brown coloured with a dark band over the head and a dark pattern over the body that camouflages well with shadows in the water. They are a docile shark most active at night, during the day they congregate in caves or under ledges. In spring they migrate to breeding areas up to 850kms away.

Habitat:

Coastal waters around reefs, rocky estuaries to about 250m deep.

Notes:

Spotted this shark at the Sydney aquarium. A breeding program at the aquarium releases these sharks back into areas around Sydney.
