When a fisherman caught a bull shark recently off the Florida Keys, he came across an unlikely surprise: One of the shark's live fetuses had two heads.
The fisherman kept the odd specimen, and shared it with scientists, who described it in a study published online today (March 25) in the Journal of Fish Biology. It's one of the very few examples of a two-headed shark ever recorded — there about six instances in published reports — and the first time this has been seen in a bull shark, said Michael Wagner, a study co-author and researcher at Michigan State University.

Great white sharks back in Red Triangle. Scientists are all but running giddily into the surf with fancy new gadgetry as the annual migration of great white sharks hits full swing along the Pacific coast and reports flood in about finned beasts lurking in shallow waters.
The ferocious predators have returned to their feeding grounds in the so-called Red Triangle, an area roughly between Monterey Bay, the Farallon Islands and Bodega Head, but sharks have been spotted all along the coast, including a 20-footer seen last weekend next to Moss Landing Harbor. The appearance of the great whites could not come at a better time for researchers, who recently deployed a new robotic device that can identify and track the movements of sharks and other fish equipped with acoustic monitoring devices.

The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan. "It's very surprising because no one's ever seen shark hybrids before, this is not a common occurrence by any stretch of the imagination," Morgan, from the University of Queensland, told AFP. "This is evolution in action. " Colin Simpfendorfer, a partner in Morgan's research from James Cook University, said initial studies suggested the hybrid species was relatively robust, with a number of generations discovered across 57 specimens.
