Smooth leatherjacket

[3] The species is found from Cape Naturaliste, Western Australia, to Sydney, New South Wales, around Tasmania, and around the waters of New Zealand.

[4] Leatherjackets have a hard, sandpaper-like exterior which they use as a defense mechanism, which causes the fish to swim slowly.

Because of this, the diet of leatherjackets is atypical, focusing on slow-moving species such as sponges, sea squirts and barnacles.

[3] Leatherjackets developed a reputation for being bold among Māori in New Zealand, who named the fish kōkiri, a Polynesian word used to describe species such as triggerfish.

The fish was one of the most commonly found in middens from the archaic period of Māori history.
