Book/DVD recommendations on sharks please?

[dubatatamama]

Both DC (4.5 and 3.5) have become obsessed with sharks. DS however is very sensitive to "scary" stuff. Anyone have any book or DVD recommendations about sharks that don't show attacks on people and blood? Something that might just talk about the types of sharks, what they eat, etc.

Thanks!

Our library has a pretty good collection of the eyewitness dvds that my kids love including one of the favorites, the shark one http://www.amazon.com/Eyewitness-Sha...8826056&sr=8-2
