Otters in the zoo

The otter is a large beast with an elongated flexible body streamlined.

Fur color: dark brown on the top, light underneath, silver. The remaining hair is coarse, but the underfur is very thick and delicate. The high density of the undercoat makes the fur impervious to water and perfectly insulates the body of the animal, protecting it from hypothermia.
Otters are quite sociable animals, they have a wide range of sounds: communicating with each other, they hum, yelp and yelp, during a game or pleasure they chirp, while calling for relatives (for example, mothers of their cubs) they squeak, and frighten, hiss and snort . In preparation for the attack, the otters emit a long and piercing howl, reminiscent of a cat's meow
