Oriental small-clawed otter

Scientific name
Aonyx cinerea
English name
Oriental small-clawed otter

Features

They live in groups of several in water areas such as streams and mangroves. They use their long tails to swim quickly in the water and prey on small fish and crustaceans. They have the habit of marking their territory with urine and feces. They are the smallest of all otters, and their name comes from the small claws on their hands and feet.

From the breeding staff

I love the pool! I love the fish! I love taking naps!
He has a lot of cute things about him, but he also sleeps with his eyes rolled up... (laughs)

When attacked by an enemy or otherwise exposed to strong stimulation, they spit out a sticky white thread-like substance called the Cuvier's organ from their anus. This is a way to protect themselves from predators. They are the only sea cucumbers that are poisonous.

I guess it's ok to be touched by humans. Except when I feel like it, I rest in the middle.
If you find yourself in the middle, leave you alone!
