The Weather Channel has posted and excerpt from its show “Lifeguard!” that features a discussion about shark behavior with U.C. Davis researcher Peter Klimley. Shark attacks in Southern California and white shark behavior seem to be the main focus of the segment. Relative risk of attacks, attack behavior, and white shark diet are among some the items Klimley discusses.

It’s interesting to note that (in this excerpt at least) Klimley seems to suggest that shark attacks are generally the result of a defensive behavior in which the shark bites but does not remove any flesh from the victim, which may be preceded by shark threat behavior. The topics of test bites or actual instances of sharks feeding on humans are not addressed in the clip.
