Cuttlefish have a unique internal shell, the cuttlebone, used to control buoyancy. They eat molluscs, crabs, shrimps, fish, octopus, and other cuttlefish. Cuttlefish can change color and texture rapidly.
Flamboyant cuttlefish, Metasepia pfefferi, are common in the Philippines. They have a broad oval mantle.
Freshly-laid eggs are white but turn translucent, making the developing flamboyant cuttlefish clearly visible.
Broadclub cuttlefish, Sepia latimanus, are often light brown or yellow.
