Do whales attract sharks?
There is little doubt that both white and tiger sharks will be readily attracted to a floating, dead whale, and it is reasonable to assume that both species would stay within limited distance of migrating whales, probably via olfactory cues, not just from dead whales, but from the presence of bodily fluids and solids.
What happens to a dead whale on the beach?
Such very large carcasses are difficult to move. 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.

While they do have 300 rows of teeth in their giant mouths, whale sharks don’t use them for eating. Each of their 3,000 teeth is tiny—less than half the size of an aspirin—and marine biologists aren’t even sure of their purpose. Whale sharks are filter feeders, like baleen whales.
Do sharks eat live whales?

Can a shark smell period blood?
Any bodily fluid released into the water is likely detectable by sharks. A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids.
Why is it illegal to touch a whale shark?
Touching whale sharks can disturb the protective mucous layer on their skin – and it can also have unpleasant consequences for you or me. The tiny, tooth-like scales (known as dermal denticles) that cover the skin of most shark species can cause a painful graze known as “shark burn”.

What do you do if you see a dead whale?
If you see a sick, injured, stranded, or dead marine mammal or sea turtle, immediately contact your local stranding network (phone numbers provided below). You can also use our Dolphin and Whale 911 app to report a stranded marine mammal. The app is available for Apple devices.
Do dead whales float or sink?
Once a whale dies, it may float at or near the ocean’s surface for a few days due to gas buildup, but eventually the carcass sinks, carried by ocean currents and often landing in the deep sea. These whale falls are rare but are most often seen along the migratory routes of living whales.

Can you survive in a whale’s stomach?
While the veracity of the story is in question, it is physically possible for a sperm whale to swallow a human whole, as they are known to swallow giant squid whole. However, such a person would be crushed, drowned or suffocated in the whale’s stomach. Like ruminants, the sperm whale has a four-chambered stomach.
What fish could swallow a man whole?

How do whales defend against sharks?
Again, by traveling in numbers, whales make it harder for sharks or orcas to target a specific member. If they feel threatened, though, whales will form a circle with their head facing inward, tail facing out. This allows them to protect the young in the middle while attacking with their tail from behind.
