Osmoregulation

As marine mammals, oceanic dolphins have low access to fresh water and constant exposure to salt water. Marine mammals must obtain adaptations when living in an environment with seawater and little to no access to freshwater. It is important for these mammals, such as dolphins, to keep maintain internal water levels and filter out excess concentrations of salt within their bodies to avoid potential dehydration.
