The leaping blenny (Alticus saliens), also known as the jumping blenny, is a species of combtooth blenny (family Blenniidae) in the genus Alticus. There is some uncertainty as to whether it was originally described by J.R. Forster in 1788 or B.G.E. Lacepède in 1800, although Fishbase currently accredits it to Forster. It was originally described as a member of the genus Blennius. Leaping blennies feed primarily off of algae. They are oviparous and form distinct pairs when mating. They can reach a maximum total length of 10 centimetres (3.94 inches).
