Marine biologist finds six pregnant male sharks

Marine biologist Alyssa Barnes discovered an unusual phenomenon in big eye hound sharks off the coast of eastern India. She observed more male sharks than females, with the males exhibiting a visible stomach bulge. Upon dissection, Barnes found that these male sharks not only had external claspers typical of males but also possessed ovaries like females. Remarkably, six out of seven dissected male sharks were pregnant, with at least two baby sharks found in one of them.

What is the significance of the external claspers found in male hound sharks?
