otters

 there are otters that live in ponds, rivers,lakes and in the Pacific ocean .river otters are not as big as sea otters .sea otters eat a lot of sea urchins  in fact if there were no sea otters in the ocean the urchins population would grow and grow they and other sea animals would eat all the plants and then there would not be anymore plants  then the sea animals would all die . so sea otters are important . river otters eat fish and live in kelp forest. here is a fun fact i know about otters i know that group of otters is called a ( raft ) otters are very fast swimmers     they have predators but humans are there greatest threat so pleas try too help otters  they are one of my favorite animals.
