Spinytail Leatherjacket
Acanthaluteres brownii
Spinytail Leatherjacket (Acanthaluteres brownii) is a small temperate sea leatherjacket from southern Australia, best known for its rough skin and very spiny tail region. It lives near reefs and seagrass beds and is not generally targeted by anglers.

Identification points
- Rough, leathery body with a laterally compressed oval shape
- Spinytail region with prominent sharp caudal spines
- Mottled brown to olive coloration with a small mouth and no large obvious scales
Habitat
Shallow coastal marine habitats, especially seagrass meadows, sheltered bays, and reef edges over sand or rubble in temperate southern Australia.
Bait notes
Rarely a targeted species; small pieces of shrimp, squid, or marine worm on light tackle may take one incidentally. Tiny soft plastics or small baited hooks near bottom structure are the most realistic options.
Behavior
Benthic and relatively sedentary, picking small invertebrates and algae from the bottom and cover. It relies on camouflage and spines for defense rather than speed.
Caution
Handle carefully: leatherjackets have very rough skin and sharp spines that can puncture fingers. Not a common table fish, and local regulations or bag limits may apply where retained as bycatch.
Fishing notes
Fish very light tackle close to seagrass, reef, or rubble in calm inshore water. Use small hooks and short casts; most captures will be by accident while targeting other small reef fishes.
