For species lacking significant blubber, such as the sea otter, the solution lies in their fur. The once distinct neck vertebrae of cetaceans have fused, giving them a sleek, torpedo-shaped body that moves effortlessly through the water.
Three Major Groups Scientists generally divide marine mammals into three distinct groups based on their evolutionary origins. True marine mammals are those that depend on the ocean for their primary habitat and food source.
