Reproduction in animals varies from species to species. Some types of reproduction, like parthenogenesis, are more unusual than others. This reproductive method requires only one individual rather ...

One possibility is that this represents a case of "parthenogenesis", a rare form of asexual reproduction exhibited in sharks that lets them give birth without needing to mate. When eggs are ...
