Bob Ellis, 29, is a dolphin trainer. "I like my job a lot because I love working with animals. It is tiring though, as I work long hours," he says.

Bob is an early bird. His day starts at live o'clock in the morning. He gets up, has a shower, and then he gets dressed. After breakfast, at about six I o'clock, he catches the bus to work. He arrives at the aquarium at half past six and feeds the dolphins. After that, they practise for the show until lunch-time. Bob has a break for lunch from half past twelve till half past one, then the show starts. At five o'clock in the afternoon, he feeds the dolphins again and then he goes home. In the evening, Bob usually watches TV. He doesn't go out very often during the week because he goes to bed early.

And what does Bob do in his free time? He loves going for long walks in the countryside with his dog, Jack. Bob also likes swimming at the pool, but he never swims in the sea because he's afraid of sharks!
