How long can a sea otter stay out of water?
The sea otter can live its entire life without leaving the water. 9. Its fur is the densest of any animal on Earth—an estimated 1 million hairs per square inch. That’s because, unlike its fellow marine mammals, it has no blubber to keep it warm.
Do otters need to live near water?
They can thrive in any water habitat, such as ponds, marshes, lakes, rivers, and estuaries—in cold, warm, or even high-elevation areas—as long as the habitat provides adequate food. River otter dens are along the water in abandoned burrows or empty hollows.
Like humans or any other mammal, they need to breathe air to get oxygen. All mammals have lungs, which are the main breathing organs. They bring oxygen into their bodies and send carbon dioxide out. Otters are semi-aquatic animals, and they need access to both land and water to survive.
Do river otters go on land?
While river otters spend most of their time in water, they do travel across land as well—often in search of a mate. Otters even make their land travel look playful. They run a few steps and then slide on their bellies.

General Ecology: Otters can travel over large areas. Some are known to use 20 kilometres or more of river habitat.
Where do otters build their homes?

How do you attract river otters?
Structural Features That Will Attract Otters
Given their habitat features and favored food types, we may conclude that river otters are attracted to mature freshwater systems. They require structurally rich riverbank or coastal zones that receive a steady supply of water (and with it, food).
What eats an otter?
What are the natural predators of sea otters? Great white sharks are the primary predator in California. Ongoing studies in Alaska recently revealed that orcas (killer whales) are eating more and more sea otters in that region, possibly because the usual prey (seals and sea lions) are in decline.
A pet dog has nearly drowned after being attacked by a group of otters. The attack happened in Alaska, when Kenny Brewer went out for an evening walk with his wife, Kira, and their dog, Ruby – a 50lb husky mix. As they walked around Taku Lake, they saw a group of river otters on a log.
