Yellowback stingaree

The yellowback stingaree (Urolophus sufflavus) is a locally abundant but little-known species of stingray in the family Urolophidae.

It is almost endemic to New South Wales, with a range from Green Cape northward, extending only barely into Queensland (Stradbroke Island).

The two species apparently hybridize, highly unusual for cartilaginous fish, and produce offspring that are intermediate in colour pattern.

In a 2007 study of 388 fishes, these two species were the only two that could not be distinguished on the basis of their cytochrome c gene sequences, attesting to a close evolutionary relationship.

This species is caught as bycatch in otter trawls and gillnets; though it is generally discarded, survival post-capture is believed to be low, and in addition stingarees tend to abort gestating young if captured and handled.
