Ostracion immaculatus is a marine fish with a box-shaped body. It has a hard shell made of bony plates that protects it from predators.
Ostracion immaculatus differs from most fish by its rigid box-like carapace, which does not allow fast swimming but reliably protects it. The fish is important for reefs because it eats algae and small animals, helping to maintain the balance of the ecosystem.
Immature form that undergoes metamorphosis before adulthood.
