The Diamond Filefish is a small marine fish with a rhombus-shaped body and a sharp spine on its back. It lives on coral reefs in the warm waters of the Indo-Pacific region.
The Diamond Filefish differs from related species by its rhomboid body shape and its ability to quickly change color. It helps maintain balance on reefs by eating algae.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
