North american river otter

They can close their nostrils during diving and staying underwater for as long as 8 minutes

Chris Paul

North American river otter has a coat ranging from grey and white to black and brown. Their thick fur comprises 850,000 hairs per square inch (6.45 cm2), insulating them from cold waters. They have narrow, long bodies with flattened heads to create a streamlined movement underwater.

They are carnivores, and their diet mainly consists of turtles, fish, amphibians, crayfish, crabs, and other invertebrates. To teach the young to forage and to catch prey, their mothers will catch and release the prey to train them. They must eat a lot during the day because they have a high metabolism.
