How do whales travel? Do they use a map? How about a compass? Or do they just follow their nose?

How do whales travel?
There are four main types of whale migration: Coastal, Transoceanic, Seasonal, and Structural. Each of these has a different purpose and happens in different ways.
Coastal migrations happen when whales follow food sources along the coastlines. This is the most common type of migration and happens throughout the year. Transoceanic migrations are much longer journeys that happen only once a year. Whales travel to mate or give birth in different areas of the ocean that have the right conditions for their young. Seasonal migrations are also common, and happen when whales follow food sources that move around in different parts of the ocean at different times of year. Finally, structural migrations are less common and happen when whales move to different areas to find new food sources or shelter from bad weather.
How do different types of whales travel?
Different types of whales travel differently. The sperm whale, for instance, is a toothed whale that feeds mainly on squid. To catch its prey, the sperm whale dives as deep as 3,000 feet (915 meters), using echolocation to navigate and find food. Orcas (killer whales) are also toothed whales; however, instead of eating squid, they eat marine mammals such as seals and dolphins. Gray whales are baleen whales, which means they have a comb-like structure in their mouth that they use to filter small organisms from the water for food.
How do baby whales travel?
As The Observer reported in February 2018, a baby whale was spotted swimming close to shore in Carcassonne, Southern France. The little mammal, no more than a few weeks old, was struggling to keep up with its mother as she headed out to deeper waters.
Sadly, this is not an uncommon sight. Every year, hundreds of calves are stranded on beaches around the world, from Massachusetts to Australia. In many cases, they are too weak or sick to return to sea and die on the shore.
So how do baby whales travel? According to marine biologist Nadine Bott, who spoke to National Geographic, young whales spend their first few months close to shore where there is an abundance of food. It is only when they are old enough and have enough body fat to survive long periods without eating that they venture out into the open ocean.
Bott added that calf survival rates are low even in the best of circumstances. Many end up as prey for killer whales or other large predators. And those that do make it to adulthood often fall victim to fishing nets or pollution. As a result, whale populations around the world are in decline.
How do whales travel long distances?
There are two ways in which whales can travel long distances: either by migrating or by making local movements.
Migration is a seasonal movement of animals between breeding and feeding grounds. Most whale species migrate annually, often covering huge distances – up to 25,000 miles (40,233 km) in a year in the case of the humpback whale. Migrating whales usually travel in groups (pods), sometimes numbering in the hundreds or even thousands.
Local movements, on the other hand, encompass all other movements that whales make that are not part of their annual migration. These include travelling to different areas to find food or mates, or simply moving from one place to another within their normal home range.
How do whales travel in groups?
Whales are often seen traveling in groups, or pods. Scientists believe that this behavior provides many benefits to the whales, including protection from predators, increased opportunities to find food, and a chance to socialize.
How do whales use echolocation to travel?
Whales use a special form of sonar called echolocation to help them travel. Echolocation is a way of using sound waves to map out an area. When a whale makes a sound, it will bounce off objects in the water and return to the whale. The whale can then use these sound waves to map out its surroundings and figure out where it is.
Echolocation is a very important tool for whales because it allows them to travel long distances without getting lost. It also helps them avoid obstacles in the water, such as rocks or other animals.
How do migrating whales travel?
There are two types of migrating whales- those that travel in pods and those that travel alone.
Migrating pods: pods are typically made up of close family members, such as a mother and her calf, or a group of adult females. Pods migrate together for protection and social reasons.
Solitary migrants: these include adult males, subadults, and juveniles. They often leave their families behind to find new territories or mates.
Whales use different techniques to travel depending on their size, body type, and the distance they are moving.
Smaller whales, like belugas and dolphins, often ride currents to save energy. Larger whales, like blue whales and humpback whales, use a technique called “fluking” to swim. Fluking involves using their tails to push themselves forward in short bursts. This is an energy-intensive method but it is very effective for long-distance travel.
There is still much we do not know about how whales migrate. Many populations have not been studied in depth and we have only recently begun to use technology like satellite tags to track whale movements. However, we do know that migrating whales face many challenges, including pollution, ship strikes, and entanglement in fishing gear.
How do whales travel to breed?
Whales travel to breed in warm waters near the equator. The journey is long and arduous, but it is necessary for the survival of the species.
How do beached whales travel?
Beached whales often travel in groups, moving slowly along the coastline. They may stop to rest in sheltered bays or estuaries. If the tide is high, they may swim out to sea. Beached whales occasionally strand themselves on sandbars or mudflats far from shore.
How do dead whales travel?
Whales are very large animals and can weigh up to 200 tons. When they die, their bodies typically sink to the bottom of the ocean. However, sometimes whales can become stranded on beaches or in shallow water. In these cases, humans may want to move the whale to a deeper location so that it does not create a nuisance or attract predators.
There are several ways to move a dead whale. One method is to attach it to a large ship and tow it out to sea. This can be difficult, however, because the ship must be big enough to support the weight of the whale and the water must be deep enough so that the ship does not run aground.
Another method is to use explosives to blast the whale into pieces that can be more easily transported. This method is controversial because it can be dangerous for people and animals nearby, and it may also cause pollution if the explosives contaminate the water with chemicals.
A third method is to bury the whale on land. This can be done on a beach or in another area where there is enough sand or soil to cover the entire body of the whale. Once buried, the whale will decompose over time and eventually become part of the land itself.
