What are 3 unique features of the humpback whale that enables them to survive in the ocean?
Humpback whales are well-adapted to move through the ocean. Their bodies are streamlined with only a few bristles for hair on top of the head, no external ear flaps, and internal genitalia.
How are whales adapted to the ocean?
To help them adapt to the ocean, whales developed echolocation, thick layers of blubber, modified lungs, better hearing, and larger arteries, among other things, to ensure their survival and prosperity.
How do humpback whales survive in the ocean?
When these marine mammals are not migrating, they prefer shallow waters and can be seen living in surface waters both in the open ocean and along the coast. There are three separate populations of humpback whales that do not interact with one another. Instead, the adult whales live off their layer of blubber.
What happens to a dead beached whale?
If a whale is beached near an inhabited locality, the rotting carcass can pose a nuisance as well as a health risk. The whales are often towed back out to sea away from shipping lanes, allowing them to decompose naturally, or they are towed out to sea and blown up with explosives.
Can whale crush itself?
Some species, such as the blue whale – the largest mammal on earth – are so heavy that their body weight would crush their own organs after a very short spell out of water. The majority of whales that beach, however, don’t make it back out to sea.
Who owns a beached whale?
Under the law of the United Kingdom, whales and sturgeons are royal fish, and when taken become the personal property of the monarch of the United Kingdom as part of his or her royal prerogative.
Where do whales die?
Stranded. Not all whales sink to the bottom of the ocean when they die, however. Some instead become stranded on coasts around the world. Although efforts are often made to save them, without water to maintain their buoyancy, the weight of the whale’s own body soon begins to crush the internal organs.
How long does it take a whale carcass to decompose?
Decomposition of a whale fall occurs in three distinct stages, each of which benefits different marine species. The first stage allows animals like hagfish and sleeper sharks to pull soft tissue (including the abundant fat stores) from the whale’s carcass; this stage can last a few months or as long as 18 months.
