Sea Otters are my favourite animal. I like them cause they remind me of river otters. Otters help our ecosystem majorly. They eat Kelp, Sea urchins, small fish and other things. Without these creatures there would be mass emounts of Kelp and fish. Sadly Sea Otters are endangered of becoming exstinct due to oil spills and pollution. They used to be very endangered and only around 500 sea otters left. Lots of people wanted Sea otters soft fur. Thanks to lots of shoreline clean ups and less oil spills Sea otters population is getting higher but its still very low.
