Although the specific reason for Ralphs and Nortons deaths is uncertain, I think that Dr. Carlson provides good theories concerning their deaths. I think that it is ok for these whale sharks to be held in captivity, like Dr. Carlson said, it helps scientist get to know the sharks more, and then help the other sharks in the ocean. As I mentioned, I do not TOTALLY agree it works, which means I do a bit, but am not sure about the solid connection.

The whale shark was fed with a tube after it seemed to lose its appetite over a period of months last year, said Robert Hueter, director of the center for shark research at the Mote Marine Laboratory in Sarasota, Fla., who participated in the examination of the shark's body.
