Sea otter vs. Sea urchins The sea otters at the Oregon Coast Aquarium were given live red and purple sea urchins as enrichment. Oswald seems to have scooped up all of the urchins for himself 😂 You might say he has a taste for uni! This video is a great example of how sea otters utilize tools to open their prey. Here we witness Oswald utilizing the hard glass surface to crack open a purple sea urchin, which in the wild, he’d use a rock instead. As a keystone species in kelp forests, sea otters help control the sea urchin population so the urchins don’t overgraze on kelp. But here in Oregon, we’ve hadn’t had a population of sea otters for over a century due to being extirpated for their fur by hunters. The Elakha Alliance is working hard to restore this marine mammal to benefit our nearshore marine ecosystems and return a cultural significant species to coastal tribes. #seaotters #seaotter #otters #Oregon #oregoncoast #kelpforest #kelp #seaurchins
