Demographic studies hope im right
<span>Marine mammals can be classified as animal that lives
partially or wholly on coastal waters or oceans from survival while fish can be
classified as a cold blooded gill bearing, egg producing species. However,
whales survive by the development of echolacation, modified lungs, thick layers
of blubber and lager arteries among
other things to ensure their prosperity and survival.</span>
C just trust me with this.
