Orange-spotted rabbitfish
Siganus guttatus
Family Siganidae
updated Oct 2016

Where seen? This gaily spotted fish is sometimes seen on on our Northern shores, among coral rubble. Sadly, often encountered trapped in driftnets. It is said to be found in turbid reefs near mangroves and appears to prefer places with lower salinity. Young fishes settle in seagrass beds near river mouths while adults leave and enter rivers with the tides. Adults travel in groups of 10-15. Unlike other rabbitfishes, this species is said to be active at night.

Features: To about 40cm, those seen about 15-20cm. It is distinguished by the spotted pattern and large golden spot below the dorsal fin near the tail which is about the same diameter as the eye. The upper body is dusky blue, and lower body silvery. The head has lines and spots. It has stout, venomous spines.

Painful sting! The rabbitfish has spines on its fins that are grooved and contain venom glands. These spines may be found on the dorsal, anal and pelvic fins. The sting of these spines can be quite painful to humans, but is generally not fatal. The fishes use their spines in self-defence and not for hunting prey.

How to stay safe: Wear covered shoes. Don't handle rabbitfishes.

What does it eat? It eats algae that grows on the sea bottom.

Human uses:
Sold fresh in some places as food.
