How do whales protect themselves from sharks?

How do whales defend themselves against these predators? The largest species possess a formidable weapon: their tail. A humpback whale or a sperm whale can injure or frighten off a predator with a violent thump of its tail. The larger dolphins can also frighten, injure or even kill a shark with a violent head butt.

Why don t sharks take bites out of whales?

Oh, they will try to bite chunks out of blue whales, but a small shark won’t leave large marks on the whale’s skin and there’s a thick layer of blubber below the skin that protects the whales against the more serious bites. A small shark can bite into a whale without leaving a large mark.

How do whales protect themselves from the cold?

Whales are warm blooded marine mammals that can tolerate cold water temperatures. Whales use blubber as an insulation layer to help maintain the energy and warmth when they dive to cool depths or travel to cold waters such as in Alaska. The blubber layer is a thick (6 inches) layer of fat that is found under the skin.

How deep can a whale dive?

The deepest recorded dive was 2,992 metres, breaking the record for diving mammals. Experts have suggested that this dive was unusually deep for this species. A more normal depth would be 2,000 metres. Sperm whales also regularly dive 1,000 to 2,000 metres deep.

Can cold blooded animals freeze to death?

While invertebrates like the Antarctic midge, and cold-blooded animals like the wood frog, have evolved to tolerate some freezing inside their bodies, this just isn’t a possibility for mammals.

What animals can live in freezing conditions?

Can fish freeze and come back to life?

The surprising answer is yes, sometimes. It is true that some fish can spend the winter frozen in ice and come out swimming once the ice melts. Moreover, some fish contain a kind of antifreeze substance that allows them to survive very cold conditions.

Can you freeze a bee and bring it back to life?

No, they can’t. Most insects can survive below subzero temperature, many can abide the freezing of their body fluids while some go through adaptations that helps to avoid freezing.

What to give a dying bee?

The RSPB suggests getting a small container or spoon and offering two tablespoons of granulated white sugar to one tablespoon of water. If you have your Bee Revival Keyring, this is an easy step for your spontaneous encounter with a tired bee.

Do crabs die in the freezer?

You should never freeze live crabs. Live crabs stored in temperatures below 32° Fahrenheit will quickly perish. Any bacteria or undigested food within the crab’s insides will cause its meat to rot-even in freezing temperatures.

Is boiling live crab cruel?

Crabs and lobsters have a tough time at the hands of humans. In most countries, they are excluded from the scope of animal welfare legislation, so nothing you do to them is illegal. The result is that they are treated in ways that would clearly be cruel if inflicted on a vertebrate.
