About this species
Irolita is a genus of softnose skates in the family Arhynchobatidae, commonly known as round skates. There are two species, both endemic to Australia, found over soft bottoms on the outer continental shelves and upper continental slopes, at depths of 50–200 m for the southern round skate and 142–209 m for the western round skate. The distributions of the two species do not overlap.
