In some animals, however, the shunt remains open after the animal is born, compromising its liver function, slowing growth, and eventually resulting in death of many affected animals.
Sea Otters favor confined areas, such as bays and inlets. They stay in areas where the water is less than 130 feet deep, but travel through much deeper water. Sea Otters do not live in deeper waters because then it is a longer dive for them to catch their food.Sea Otters hang in groups called rafts; they usually hang out by waters near shore or kelp beds and where shellfish are plentiful.

Food Habits: Sea otters mainly eat benthic invertebrates such as clams, mussels, urchins, crabs, and fish. They must dive to capture their food, sometimes up to 250 feet. Sea otters also use âtoolsâ such as a rock to open their hard-shelled prey.ur: Sea otter fur is the finest of any mammal, consisting of 850,000 to 1 million hairs per square inch. Sea otters depend on these hairs to keep them warm while in the water. If a sea otterâs fur becomes soiled with foreign substances such as oil, the sea otter will not be able to keep itself insulated.
