The thornback cowfish displays a yellowish to greenish coloration with irregular patterns of bluish or brown spots and lines across its body.
Range
The thornback cowfish is found throughout the tropical Indo-Pacific, especially in the Bali sea, from east Africa to the Bass islands.
Habitat
The thornback cowfish lives in coral reefs and seagrass beds, where it easily hides thanks to its patterns
Did you know ?
The thornback cowfish is a poisonous species of boxfish. Indeed, when stressed or threatened, it secretes toxins as a means of defense against predators
Unlike other fish, the boxfish’s body is covered with a rigid shell made of bony plates, which protects it like armor from predators but also limits its body movements. As a result, the boxfish moves more slowly by undulating its dorsal and anal fins.
