How Sea Otters Could SAVE the Ocean | A Deeper Dive

#seaotter #otter #kpassionate Sea otters are something known as a keystone species. Which are species that play a critical role in maintaining the stability and health of their environment. It’s just like a keystone in an arch. While the keystone is under the least pressure of any of the other stones, without it the entire arch would collapse. This is exactly what happened between the years 1741 and 1911, Sea otters were hunted extensively for their fur, and their population fell from hundreds of thousands to just one to two thousand individuals living in a fraction of their historic range. In fact, so few otters remained that most scientists believed the species would become extinct. This had a devastating effect on the marine ecosystem. And it had everything to do with a sea otter’s impressive metabolism. They need to eat a quarter of their body weight every single day. One of their favorite things to eat are sea urchins. Sea urchins are voracious eaters. In fact, they are often the dominant herbivore in their environment. And their favorite food… is kelp. So when the population of sea otters plunged the population of sea urchins soared. Left unchecked, these prickly echinoderms decimated the kelp forests. Turning the once vibrant ecosystems into underwater wastelands. Something called an urchin barren. Some of these urchin barren stretch for thousands of kilometers. But there is good news. Thanks to conservation efforts, reintroduction programs, and an international ban on hunting, sea otter numbers have rebounded in about two-thirds of their historic range. This recovery is widely considered one of the greatest successes in marine conservation. This also means that the kelp forests are returning, providing protection and nutrition to the countless animals that call them home. --------------------------------------------------------------------------------------------------------------------------- If you want to support the channel check out my Patreon!
