The saddled gunnel is a small marine fish with a long body and dark saddle-shaped spots on its back. It lives along rocky shores of the northern Pacific Ocean and can stay out of water for some time during low tide.
The saddled gunnel differs from related species with its bright saddle-shaped spots and ability to live out of water during low tide. It is important for nature because it eats small invertebrates and serves as food for larger fish, birds, and marine mammals.

Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
