Last year this eel was found for the first time in an ocean cave in Palau.
It is so different from common eels that it is not only a new species, it is a new genus too, Protoanguilla palau is its full name, and it has been around for millions of years.
It is thought that there are thousands and thousands of animals still waiting to be discovered, especially in the oceans and underground.
