The ornate cowfish (Aracana ornata), like all cowfish, has a skeleton made of fused bones, essentially trapping it in a barely-flexible box. For this reason, these fish are typically slow movers; however, it does have an advantage: few other fish are able to eat adult cowfish.

Moray eels are a type of fish belonging to the family Muraenidae. Perhaps one of their most interesting qualities, morays have a second jaw (think Alien), called the pharyngeal jaw, that helps them consume food. This particularly comes in handy because the size/shape of moray eel mouths make it incapable of producing the negative force that helps other types of fish suck food in. Instead, morays catch their prey with their primary jaw and the pharyngeal jaws come forward to pull the food in further, preventing escape.

Chitons are mollusks belonging to the class Polyplacophora. They are mostly flattened with eight dorsal, limy plates. This is where they get their class name from. (Polyplacophora means “bearing many plates.”) These plates overlap posteriorly and are typically dull in color to blend in with their surroundings (though this is not always the case). Most chitons rarely grow larger than 5 cm and the largest rarely ever exceed 30 cm. They’re usually found stuck onto rocky surfaces in the intertidal zone, but some have been found at much greater depths. If a chiton gets detached from its rock, it can roll up like an armadillo for protection.

Shown is the mossy chiton (Mopalia muscosa), whose mantle is covered in defensive hairs and bristles.
