Black-faced blenny 2007) and "T. tripteronotum" (Risso, 1810). Besides "T. delaisi", all species are endemic to the Mediterranean Sea. The species "T. delaisi" is subdivided in two subspecies: "T. delaisi delaisi" in the Mediterranean Sea and "T. delaisi xanthosoma" in the Atlantic Ocean. The subspecies can be distinguished by their courtship behaviour: "T. delaisi delaisi" court in free water and "T. delaisi xanthosoma" stay on the ground for courtship behaviour. The speciation process is still under discussion and several hypotheses have been proposed. Black-faced blenny The black-faced blenny ("Tripterygion delaisi") is a small benthic fish from the family Tripterygiidae (triplefin-blennies). It occurs
Leaping blenny Leaping blenny 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 first 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". It is a tropical blenny known from the Pacific and Indian oceans, including the Red Sea, the Society Islands, the Ryukyu and Bonin Islands, Queensland, Australia; and the Mariana Islands.
