Pacific leaping blenny Pacific leaping blenny The Pacific leaping blenny ("Alticus arnoldorum"), also known as the leaping rockskipper, is a species of combtooth blenny (family Blenniidae) in the genus "Alticus". The blennies are oviparous, and form distinct pairs when mating. Males can reach a maximum total length of 8 centimetres (3.15 inches). These fish feed primarily on benthic algae, which they consume by scraping off rocky surfaces. The Pacific leaping blenny is a tropical blenny found in reefs in Samoa and the Marianas, Society, and Cook Islands, in the western and southern Pacific Ocean. The blennies are noted for leaping from hole to
Sphinx blenny mating, the blennies form distinct pairs, and the females lay up to 7000 eggs in a sitting, which are then guarded in burrows by the males. Males are known to cannibalize dead eggs to prevent infection spread amongst the healthy eggs, although in smaller broods they have also been reported consuming living eggs. It is believed that this is due to limited feeding opportunities for the males during breeding, as a result of their restriction to the nests. FishBase considers the blennies to be of Low Vulnerability, with a reproductive doubling time of less than 15 months. Sphinx blenny The
