Do blue whales migrate to Australia?
The migration of the Blue Whale unfolds every year and is centred around finding krill. During the summer months the Blue Whales gather to feast on krill swarms in the Bonney Upwelling located off the southern coastline of Australia.
How long does a blue whale migrate?
When it comes time to mate, they will travel thousands of miles to warmer tropical waters. It is estimated that blue whale migration can last for up to four months.
Do blue whales migrate or hibernate?
Blue whales are found in all oceans except the Arctic. They generally migrate seasonally between summer feeding grounds and winter breeding grounds, but some evidence suggests that individuals in certain areas might not migrate at all.
Are blue whales friendly?
As a species, whales are generally non-violent and do not display aggressive behaviors towards humans; however, in situations where a whale may feel threatened or frightened, it may defend itself by attacking what it thinks is a potential threat.
Do blue whales still exist?
Sadly, there are only about 10,000 to 25,000 blue whales left in the world today. Though it may sound like a large number, this is incredibly low. The populations of the blue whale have decreased exponentially since about 1911.
Do blue whales migrate to give birth?
However, despite their massive size and weight, blue whales and their travel patterns remain largely a mystery to scientists all over the world. Much like some of their smaller counterparts in the animal kingdom, blue whales migrate seasonally in search of food and possibly calving and nursing areas.
What would happen if the blue whale went extinct?
Humans selectively fish out the largest species from Earth’s oceans, causing their populations to dwindle. If that weren’t alarming enough, the extinction of those animals—think great white shark, bluefin tuna, and blue whale—could ripple down the food chain and spell extinction for entire ecosystems.
What whales are migrating right now?
Gray whales are migrating along California’s coast right now. Here’s where to see them. A baby gray whale swims with its mother off Dana Point. The gray whales are back, hugging the California coast while they make their 10,000-mile journey from Alaska to breed in the warm-water lagoons of Baja, Mexico, and back.
Which direction do whales migrate?
Southern Hemisphere humpback whales migrate north each winter from their Southern Ocean feeding grounds to warmer waters to mate and calve.
What months do blue whales migrate?
They like to spend the winters in temperate and subtropical regions, migrating to the polar regions in the spring and summer. The whales in the North Atlantic migrate to the Arctic during the summer and spring seasons.
Do blue whales mate for life?
Whales are an extremely social and caring species that protect each other and nurtures their young; however, when it comes to having a lifelong mating partner, the short answer is, “no whales do not mate for life”.
How rare is it to see a blue whale?
As blue whales are extremely rare, places where you are sure to spot them are just as rare. On the other hand, their annual migration routes are well known. Blue whales usually travel back and forth between tropic and polar waters, so in theory you could meet them in any sea all over the world.
Do blue whales live in pods?
Blue whales are generally loners, rarely if ever forming pods like other kinds of whales. At most a blue whale might pair up with one other blue whale as they search for food. They may come together with more blues in areas with high concentrations of food, but they don’t form any larger groups with the others.
How many babies can a blue whale have at once?
Baleen whales give birth to a single calf. In most species, a female may bear a calf every two to four years. If twins are conceived, they are unlikely to survive to full term. In rare cases where twins are born, they are not likely to survive due to the limited milk supply from the mother.
Is a blue whale’s heart?
To power their humongous bodies, blue whales are equipped with a huge heart as well. The whale’s heart is about 5 feet in length, 4 feet in width and 5 feet in height, and can weigh as much as 175 kilograms, which is the same as some cars.
How do whales get pregnant?
Whales fertilize internally so the male will deposit his sperm in the female fertilizing one egg. The females will carry the singleton baby for almost a full year with the gestation lasting 11 months. Whales are not monogamous and males and females do not form tight bonds after mating.
Can the human ear hear whales?
Sound frequencies are measured in units called Hertz. The range of frequencies that whales use are from 30 Hertz (Hz) to about 8,000 Hz, (8 kHZ). Humans can only hear part of the whales’ songs.
Is Megalodon bigger than the blue whale?
Some larger estimates do exist (placing megalodon up to 67 feet in length and well beyond 50 tons), but the fact of the matter is megalodon was smaller than a blue whale. In terms of size, a blue whale gets the advantage. Blue whales are larger and heavier than a megalodon.

Whales provide important nutrient recycling services in ocean ecosystems. When they poop, they recycle nutrients — including iron — back into the sea. These nutrients are then consumed by smaller ocean creatures like phytoplankton, which helps to keep oceans healthy.
How do whales sleep without drowning?
So how can they sleep and not drown? Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.
How can you tell a whale from a shore?

Threats. Like other large whales, blue whales are threatened by environmental change including habitat loss and toxics. Blue whales can also be harmed by ship strikes and by becoming entangled in fishing gear.
Do blue whales have predators?
