Asexual reproduction is common in some insect species, rarer in reptiles and fish, and has never been documented in mammals. Until now, sharks were not considered likely candidates.
Marine biologists say they have obtained the first proof that sharks can spot changes in magnetic fields, boosting evidence that the fish have an internal compass to guide them as well as a phenomenal sense of smell.
