Description

The ornate cowfish is a boxfish from the eastern Indian Ocean, endemic along southern Australia. The species grows to about 15 cm and has an angular body in a bony carapace; males are very colourful with blue and yellow lines and spots on a yellowish-brown ground, females have a striking banded pattern. It lives on seagrass beds and rocky reefs and eats small bottom invertebrates. Because of its rigid carapace it swims slowly with sculling fins. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
