DNA evidence has helped identify 113 new sharks and rays—including a skinny saw shark, a swell shark that looks like it swallowed a Frisbee, and a river shark (see photos)—scientists announced Thursday. Nearly half of the newly named sharks and other species are found only around Australia. The discoveries increase the continent's tally of known sharks and rays by a third. One of the new fish, the collared carpet shark, is so rare that the only known specimen was found in the belly of another shark.
Some of the new species are already threatened with extinction, scientists say, and many of the sharks and rays have yet to be named.
