Otters are some of the most adorable aquatic animals. Their mannerly features are unparalleled, from their expressions to their employ of tools.

Held every twelvemonth during the concluding week in September, Body of water Otter Sensation Week spotlights the important part of sea otters in nearshore ecosystems of the North Pacific Ocean. Go ready for some awesome otter facts and photos. Nosotros promise that y'all'll exist otterly entertained!

1. Forget everything you thought you knew well-nigh otter species. Thirteen different species be around the globe. The U.S. is home to ii species: the sea otter and the North American river otter. River otters are much smaller — averaging 10-thirty pounds — with a cylindrical trunk and small head. Sea otters counterbalance more — around 45-90 pounds — with big, furry faces.

3. Nearly sea otters call Alaska home. Approximately 90 per centum of the world'south ocean otters live in coastal Alaska. Many live in the waters surrounding public lands including Kodiak National Wild fauna Refuge, Kenai Fjords National Park, and Glacier Bay National Park. Southern sea otters range along the mainland coastline of California from San Mateo County to Santa Barbara County, and San Nicolas Island.

4. U.Southward. and international law protects threatened bounding main otters. Hunted to the border of extinction by fur traders in the 18th and 19th centuries, the few remaining sea otters (nearly ii,000 scattered in remnant colonies throughout the North Pacific rim) were starting time protected by the International Fur Seal Treaty in 1911. Sea otters in the U.s.a. received additional protections with the passage of the Marine Mammal Protection Act and the Endangered Species Human action in the 1970s.

v. Body of water otters eat 25 percent of their torso weight in nutrient every day. Sea otters' diets include sea urchins, crabs, mussels, and clams, which they're known to crack open with a rock and swallow while floating in the water. To find food, sea otters may occasionally swoop as deep as 250 feet and will use their sensitive whiskers to locate small-scale prey inside crevices or their strong forepaws to dig for clams.

6. Sea otters take the thickest fur of any animal. Their fur contains between 600,000 to 1,000,000 hair follicles per square inch. Dissimilar most other marine mammals, otters lack a blubber layer. Instead, they depend on their dumbo, water-resistant fur to provide insulation. To go along warm, sea otters spend a large portion of their days preparation and workout their fur. This traps air and heat adjacent to their skin.

7. Sea otters can have a pup any time of the year. Southern ocean otters brood and pup year-round, while northern sea otter pups in Alaska are usually born in the bound. A newborn pup needs constant attention and will stay with its mother for six months until it develops survival skills. Fun fact: An otter pup'southward fur is so dense that it tin't dive underwater until it gets its adult fur. This comes in handy when mothers exit their pups safely floating on the water's surface while they forage for food.

Don't claiming otters to a breath holding contest. An otter's lung chapters is 2.5 times greater than that of like-sized state mammals. Sea otters accept been known to stay submerged for more than than 5 minutes at a time. River otters, however, tin can agree their breath for up to 8 minutes. The increased time underwater improves otters' opportunity to sense prey and forage for food.

9. Otters are an essential keystone species. A "keystone species" is a species that is disquisitional to how an ecosystem functions because information technology has large-scale effects on the communities in which it lives. Along the Pacific declension, bounding main otters assistance command the sea urchin population. Fewer sea urchins in plough aid prevent kelp forests from being overgrazed. In California, enquiry has constitute that sea otters also enhance seagrass beds, and in Alaska'south Glacier Bay National Park, sea otters' expansion into the surface area marked a gradual return of a more various ecosystem and an exciting moment in colonization efforts.

x. The otter is one of the few mammals that utilize tools. A sea otter's tool of pick: typically a rock that tin can exist used as a hammer or anvil to break open hard-shelled prey. Ever wonder where otters actually store these tools for safe keeping? They have a loose patch of skin under their armpit to store both the food they've foraged and their rock to crack it open.

xi. A group of resting otters is chosen a raft. Otters love to rest in groups. Researchers accept seen concentrations of over 1,000 otters floating together. To keep from drifting abroad from each other, body of water otters volition wrap themselves upward in seaweed, forming something that resembles a raft.
