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.
