Dolphins are a lot of fun and extremely intelligent animals. Like the killer whale, they are members of the toothed whale family, so they are actually related to one another. I think the two things that surprised me the most when I first started training dolphins was their speed and coordination. They have very sensitive skin and really like to be being petted much like a dog. They kind of feel like a "wet watermelon". Most trainers that have had a chance to train dolphins will probably tell you they are one of the most fun animals to work with. They always look like they're smiling....I think it's because it seems like they always are such happy animals!
