Smart dolphins use tool to fish

Okay, we always knew dolphins were intelligent. But they're doing something new.

It seems that some dolphins have learned how to trap fish by using a large conch shell. It's pretty amazing. Not only that, but the researchers report the practice is spreading. Apparently unintiated dolphins are watching others who use this method, and learning from them. The researchers plan to follow this learning process to see if it spreads far and wide.

Very cool.
