英語(yǔ)聽力：自然百科 Hippo Spa 河馬也水療

How do you like a behind-the-scenes look at one of the nature's most luxurious full service, hippos' spas.

Our dominant male hippo customer has already arrived here at the Mezima Spring in Kenya, Africa. The carp goes right to work. It uses its wide, vast big mouth to scour the hippo's hide. The hippo gets squeaky clean skin, and the fish gets a rich buffet of dead skin, algae andparasites.

How about that tail that looks kind of like a toilet brush, the cichlid fish takes care of that. Now how about, well, how can I say this discreetly, the hippo's hindquarters, where the hippo produces hippo dung. The barbel fish eagerly dives in here, especially when the hippo was in dung production mode. The barbel is so eager for what the hippo is trying to get rid of that they will race after him like an autograph seeker chasing a rock star.

Finally,the hippo opens its mouth, home of the good stuff. And fish rush in like hungry shoppers at a half-off big sale.
