Aracana ornata, also known as the ornate cowfish, is a species of deepwater boxfish native to southern Australia. First described by John Edward Gray in 1838,[1] the species has a maximum length of 15 cm. They can be differentiated from their close cousins, the striped cowfish, by the upright look of the spines near their eyes,[2] and their slightly smaller length.[3] Their body is encased in a rigid box-like carapace composed of large sculptured bony plates; bony ridges with large recurved spines, dorsal and anal fins opposite and far back on the body, and bony plates on tail base absent/rudimentary.[4]
Ornate cowfish are sexually dimorphic; males have yellow or blue lines and spots, while females are plain with orange-brown stripes.[2] These fish are rarely kept as pets by aquarium hobbyists, as stress can cause them to release ostracitoxin from their skin, easily killing other fish in a tank.
