Dinichthys, also known as Bonefish, are aquatic predators that grow to around thirty feet long. Their head and thorax are covered by articulated armoured plates. The plates on the head and mouth create a shear cutting surface in lieu of teeth.

The bonefish is a hypercarnivous apex predator, easily capable of killing a great white shark. During the events of The Scar, Armada suffers a bonefish attack that results in the death of one of the captive guard great white sharks and several divers.
