Did you know that sea otters have 600,000 to 1,000,000 hairs per square inch! They don’t have any blubber or extra fat to keep them warm, so they rely on their water-resistant fur. In Resurrection Bay the warmest water temperature is on average 55.4°F / 13.0°C, and the coldest is on average 38.1°F / 3.4°C. To also help stay toasty sea otters have an extreme metabolism, they must eat one-fourth of their body weight a day. Hungry and hairy!
