It’s National Sea Otter Awareness Week, and we’re excited to celebrate this otterly adorable marine mammal. Did you know: #Seaotters eat 25 percent of their body weight in food every day? Their diet includes sea urchins, crabs, mussels and clams, which otters are known to crack open with a rock and eat while floating in the water. Sea otters aren’t just cute, they’re an essential keystone species, keeping their ecosystem in check. They control the sea urchin population, which in turn prevents kelp forests from being overgrazed. Photo courtesy of Ron Eby. #usinterior #travel #cuteanimals #animals
