How do humpback whales catch prey?
While other baleen whales feed by swimming rapidly forward, humpbacks are adapted for fine-scale movement to create bubble nets. These whales create bubble nets to corral and contain planktonic prey into a small area so that they can more efficiently scoop them up in their large filter-feeding mouths.
Are humpbacks endangered?
Least Concern (Population increasing)
What do whales use to navigate?
Toothed whales, like orcas and dolphins (which are in the whale family), use a form of sonar called echolocation, making clicks and pops that reflect back to them, telling them the locations of things around them.
Do whales know where they are?
For scientists, the only way to work out what a toothed whale eats is to either observe it hunting and eating, or look at the stomach contents of dead whales. The deep ocean is so dark that it is difficult for whales to locate prey by sight, so toothed whales use echolocation to find their prey.
How do whales die?
Natural Causes Cetaceans can simply die from old age. Their lifespan ranges from a few decades for harbour porpoises to over 200 years in case of bowhead whales. Moreover, whales can die from diseases, parasites and even difficulties during birth, just like us.
Do whales explode?
Most scientists agree that whale explosions are unlikely. That’s because a dead whale’s skin will gradually form small tears, which will release some of the built-up gas. Whale explosions are more likely to happen if humans interfere with the corpse.
What are the 2 major types of whales?
There are two types of whale; baleen and toothed. The key difference between them is the way they feed and what they have inside their mouth. Baleen whales have baleen plates, or sheets, which sieve prey from seawater.
What animal can swim the deepest?
A new study of elusive Cuvier’s beaked whales shows they can dive to nearly 10,000 feet (3,000 meters). A new long-term study looking at the elusive Cuvier’s beaked whale reveals the deepest and longest dives ever seen among mammals.
Which whale can stay underwater the longest?
Curved Beak Whale
Why do whales die when they beach?
When a whale beaches, it’s a race against time. Usually supported by the water, a whale’s body weight will crush it on land. Out of the water, a whale’s thick blubber can also cause it to overheat. Like other mammals, whales breathe air, so they can drown when stranded if water enters their blowhole at high tide.
Why do whales explode?
Exploding whale describes a number of actual real-world occurrences of carcasses of beached whales detonating due to an accumulation of gases internally to the whale corpse during the decomposition process.
