Baxter the North American river otter wants to tell you how he's feeling

Baxter the North American river otter lives in a public aquarium in San Francisco. According to the filmer, sometimes his keepers have to wake him up to clean the area or offer food. "When he doesn’t want to wake up or move, this is how he reacts," she says. The video shows Baxter opening his mouth out wide and letting out a loud squark-like sound.
