Protected like a pineapple

The scales of the Japanese pinecone fish have developed into large, thick, plate-like scales fortified with ridges. The scales (or scutes) form an effective armour that protects the fish against bites by other fish and from injury. The yellow scales (scutes) are edged in black. They make the pinecone fish resemble a pineapple.

Light-emitting photophores

The pinecone fish is active at night. It has a pair of small, light-emitting photophores on its lower jaw. We are not entirely sure why the Japanese pinecone fish have these photophores. It may use them to seek out prey during the night.
