Expectant sharks return home

A team of researchers from the Taronga Conservation Society Australia and Macquarie University in New South Wales, recently observed female sharks in Port Jackson returning to where they were born to give birth.

Although this behavior is the first to be observed in egg-laying sharks, Dr. Demian Chapman says this is no different than the behavior of live-bearing female sharks.

But why do both types of expectant sharks return home? It’s their way of keeping their offspring safe until they are grown.

Dr. Champman’s research focuses on shark conservation. More on his research at globalfinprint.org.
