Fish Fart

Researchers heard a small cricket like chirping noise in the water. But they discovered the truth. They had got the first recordings of fish actually farting! A tiny submarine recorded the sounds off the coast of South Florida. I thought this was really strange, can fish and other animals fart? Since the fish farted that means it can probably poo and pee. It seems strange, fish pooping and peeing. Does this mean that other animals can also fart and do other stuff? Can every animal make waste too?Are we swimming in fish fart, poo, and pee when we go to the beach? I hope not.
