The Fisher's seahorse is a small marine fish found only off the coasts of the Hawaiian Islands. Its body is covered with bony plates, the head resembles that of a horse, and the tail is used for attaching to underwater objects.
The Fisher's seahorse differs from other seahorses in that it lives only around the Hawaiian Islands and has a unique pattern of bony plates. It is important for nature because it eats small crustaceans and serves as food for large fish.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
