Marine Mammal Noise Exposure Criteria: Initial Scientific Recommendations. If a cetaceans health becomes compromised, normally innocuous populations of whale lice (pictured) and barnacles living on the animals skin can become unmanageable. They do not have gills, so they cannot get oxygen from water. When marine mammals sleep and swim at once, they are in a state similar to napping. Must Sharks Keep Swimming to Stay Alive - Live Science If unable to reach the surface, or if in a panic, the animal may dive deeper, where it will be unable to breathe and suffocate.

The longest lived cetacean is thought to be the bowhead whale, with researchers estimating they can live over 100 years. Lots of swimming will tire an infant, producing a weak animal susceptible to infection or attack. The diving response has two main effects on the body: 1) reduced blood flow to muscles (peripheral vasoconstriction), and 2) reduced heart rate (bradycardia). Beaching is not limited to sick or dead animals; sometimes perfectly healthy whales end up finding themselves stuck on the beach. In British Columbia, if you find a sick, distressed, injured, or dead cetacean or sea turtle it is important to report it to Fisheries and Oceans Canada (DFO) via the Marine Mammal Incident Reporting Hotline by calling 1.800.465.4336.

They also can maintain speeds of 20-25mph . Their invasion of the sea was progressive, and therefore we are left to ponder whether in difficult times, individuals might still instinctively react as if land confers an element of safety.
