That was an interesting last one... Hmm? 40 years I would say, for the Sea Otter. Sea otters are a common animal that most people hear about, but not many actually know about. It's about the story of sea otters, an ecosystem, and why they are in fact endangered. Sea otters, however, have made a comeback and are for the most part no longer at risk and are not expected to be at risk anytime soon. Sea otters are a very common but diverse animal. They are the only aquatic member of the weasel family. Since the 1970s sea otters have become much more popular among researchers and in entertaining people. There are 3 recognized types of sea otters, including the Russian northern sea otter, the northern sea otter, and the southern sea otter. Sea otters spend most of their time in the ocean but sometimes come ashore to rest. They have water-repellent fur to keep their feet warm and webbed, ears and nostrils that close when in water. Their thick fur makes their body appear much thicker on land, than it appears in water. It also prevents them from getting hypothermia from the temperature of the water. They have 600,000-700,000 hairs per square inch to make up for the lack of fat. There are 3 recognized types of sea otters, including the Russian northern sea otter, the northern sea otter, and the southern sea otter. Sea otters are in fact mammals. Adult (southern) sea otters can weigh between 45 and 65 pounds and are some of the smallest marine mammals, considering they only grow to 4 feet. They spend much of their time grooming, grooming, squeezing water and even blowing their fur. They do much of their work and foraging at dawn and are usually resting by midday. They are a menace... half of paper... w after the fur trade it took about 200 years to slowly repopulate. One of the most diverse and fortunate species for seagrass and kelp habitats, sea otters have made a great comeback. Cambria California has and will continue to help sea otters. Furthermore, the SMCA of Canbria will continue like this. And the biggest help of all is the Endangered Species Act. They and the Sea Otter Fund continue to support research and get tax dollars for TheSea Otters. And they continue to not allow the killing of sea otters and continue to try to restore their health. Sea otters will continue to live happy lives as they repopulate and recover. If you contribute to the sea otter fund and help maintain their continued protection, believe it or not, you too can make a difference for these happy sea creatures, the amount of fish, seaweed and
