A new study has found that one of the world's strangest animals — a unique fish that lives on land and can leap large distances despite having no legs — has a rich and complex social life.
Alticus arnoldorum is a species of combtooth blenny found in coral reefs in the Pacific ocean. It was first named by Curtiss in 1938, and is commonly known as the Pacific leaping blenny or the Leaping rockskipper.
The odd lifestyle of the Pacific leaping blenny (Alticus arnoldorum) has been detailed for the first time in research findings that throw new light on how animal life first evolved to colonise the land.
The Pacific leaping blenny is a marine fish in all aspects...except for the tiny detail that it spends all its time living on land. It could help us understand how the first animals colonized the land billions of years ago.
Adult blennies shelter in rock crevices at high and low tide, emerging only at mid-tide to feed, breed and socialize in surprisingly complex ways, Terry Ord of the UNSW Evolution and Ecology Research Center said.
The study has been published in the journal Ethology.
