The Surinam toad is a very flat frog. Its scientific name is Pipa Pipa. It is mud-brown in color, and it is known for its way of reproducing. First, unlike other frogs, the male makes a sharp clicking sound instead of a croak to attract females. Then, the couple gets on top of one another, sinks to the bottom of the area of water that they’re in, and rises back up. Each time the partners float to the surface, the female produces 3-10 eggs. Very weird, I know.
