A vegetarian shark discovered

Researchers believe they have conclusive evidence that they have identified the world’s first species of omnivorous shark — the bonnethead. A relative of the hammerhead shark found on primarily the North American shore and around the Gulf of Mexico, the bonnethead derives nourishment from seagrass. Scientists previously believed this action to only be incidental, and to have no intentional physiological value. The study, conducted by scientists from the University of California and Florida International University and published in theProceedings of the Royal Society Bjournal, found that seagrass may make up 60% of a bonnethead’s diet.
