Humpback whales, a species of baleen whale, are a favorite among whale-watchers because of their frequent aerial displays. You can often see them bouncing out of the water or hitting the surface of the water with their pectoral fins, tail, or head.
Whales are mostly gray in color and can weigh between 50,000 to 80,000 pounds (22,000 to 36,000 kg). Humpback whales can grow up to 60 feet (18 m) long, with females safely being slightly larger than males.
Why do Humpback Whales Breach or Jump out of the Water?
I got a variety of answers, all of which were promising. Let us know some such reasons.
Why do Humpback Whales Breach, Do Humpback Whales Need some Air?
Whales are mammals and they need air to breathe. Adult humpbacks typically surface every 7–15 minutes. The child has to swim to the surface every 3-5 minutes.
Humpback Whales Breach Because For Fun?
Looks like the whales are having a lot of fun. Breaching occurs when the whale’s body bulges either completely or completely out of the water. Humpback whales can leap out of the water using their powerful fluke (or very tail). And while many other whale species can also breach, humpback whales tend to do it more frequently.
Humpback Whales Teach Their Children to Jump?
We know that a baby is completely dependent on its mother—for food, shelter, and in the case of humpback whales—for breathing!
Mother humpback whales take their babies to the surface soon after birth so they can take their first breath. Humpback mothers are the definition of “attachment parenting”, they never leave their baby. This is a baby, one year or so when the time comes when he feels it is time to move away from the mother.
Humpback Whales Breach to Communicate With Other Humpback Whales?
Yes! Scientists suspect that humpback whales use this as a way of communicating by hitting their tails and flukes at the surface. All the killing is believed to produce sounds to send messages to other whales, and large splashes are thought to send distant messages.
Sound travels farther and faster in water than on land, and this makes it possible for it to convey messages to other whales.
How Long can Humpback Whales Hold their Breath?
Humpback whales have the size of a full car in their fully extended position when they are fully grown. Because of such large calyces, they have the ability to saturate their blood with oxygen, and can do so in a shorter period of time than some other marine breathing organisms.
The average breathing time of a humpback whale is 5-10 minutes, the calmer a humpback whale is, the longer it holds its breath. The longest recorded time in animals was 48 minutes in Western Australia, which is equivalent to almost an hour.
How do Humpback Whales Sleep?
Humpback whales are not like us when they sleep, due to ‘unihemispheric sleep’. This simulation allows them to keep half their brain on while sleeping, allowing them to keep breathing and remain conscious.
You can see these whales swimming on the surface of the sea. But don’t take it as deep sleep. They are simply hitting the sleep button, managing to fall asleep within 30 minutes to maintain their body temperature. This state is called ‘logging’, allowing their half-active brain to do the work of breathing and monitoring.
In terms of sleeping positions, humpbacks are versatile. They can rest peacefully in the water, float on top or even sleep while floating with support. This is an interesting aspect of their marine life.
Humpback whales only sleep for half an hour? This helps them maintain their body temperature. Factors like age, health, and time of year also play a role in their sleep schedule.
Despite these facts, the complex sleep behavior of cetaceans remains difficult to understand due to the difficulty of observing them in the wild. All we can do is ensure that when humpbacks sleep, it is a fast sleep, not a big sleep.
What do Humpback Whales Eat?
The humpback whale is one of the largest marine mammals. Their diet includes many small prey such as squid, krill, herring, pollock, haddock, mackerel, capelin, salmon, and various other fish.
Baby humpback whales begin their journey by suckling milk, a thick, paste-like milk they receive from their mother that is full of fat and various nutrients. Which they suck from their mother’s nipples until they are able to hunt food and survive on their own.
Because the humpback whale has no teeth, it has to catch its food using a variety of different hunting techniques. These whales are known to use a technique known as ‘bubble netting’.
Bubble netting is a group activity that may involve up to several dozen humpback whales. One group will swim beneath the widespread fish and form a circle, which they will use to manipulate the fish together.
The group then begins to blow bubbles to stack the circle of fish and press the fish into a tight herd. Some whales may go deeper and push upward to trap the fish in the bubble net.
Once they have collected the fish, they can eat the fish by gutting them, as much as possible using a filter-feeding method. Filter feeding involves a baleen whale swimming with its mouth open towards a group of fish or krill.
The baleen teeth in their mouth act as a filter to trap prey in the baleen, keeping the prey trapped in the teeth while allowing the water to escape.
When a large group is collected in its mouth, the whale pushes the excess water out of the mouth with its tongue while trapping the prey in the baleen teeth.
Although humpback whales can consume large amounts of food, they are known to fast for large periods of time during fall/winter and survive primarily on fat stored from the food they eat.
In winter, these whales can manage to keep hunting, but this is often rare and only at selected times. When winter arrives, these whales spend a short period of time primarily mating and foraging for food.
I hope that after reading this article you will get information about Humpback Whales like why they jump or swim in water, how long they can survive under water without breathing or how they breathe. You must have come to know very well about how they sleep and their eating habits and style too.
