What is the respiratory system of blue whale?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
What do whales use for respiration?
They breathe through “nostrils” on top of their heads called blowholes. When a whale surfaces to fill its lungs with fresh air, warm air escapes from its blowhole. This escaping air turns into misty water droplets, just like your breath on a cold day, and forms a tall spray called a blow.
How do blue whales reproduce?
Blue whales reproduce via sexual meiosis. The male and female each produce haploid gametes. Male gametes are sperm, and the female gametes are eggs. A single sperm and egg fertilize to form a diploid zygote.
How does a whale reproduce?
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.
How does respiration process differ in a whale and a human being?
Answer: A whale’s lungs work like ours do, but they make the most of each breath. In one breath, a humans body can absorb about 15 percent of the oxygen inhaled. The whale, on the other hand, absorbs as much as 90 percent of the oxygen it breathes in. …
Do whales inhale and exhale at the same time?
When the animal inhales, air passes through the blowhole, nasal duct, larynx, trachea, and lastly the lungs. Same thing when it exhales, only in reverse! In large rorquals, the inhale-exhale cycle takes just a second or two. Additionally, whales have the ability to renew 90% of the air in their lungs with each breath.
How do whales inseminate?
Artificial insemination (AI) occurs when semen that has been collected from a male is placed into a female’s reproductive tract. The first killer whale born as a result of artificial insemination was born at SeaWorld San Diego in September 2001. The male calf was named Nakai.

How do whales give birth in water?
Gestation Period & Birth Process How do whales give birth? Because whales are mammals, their calves grow inside their mothers and are born through live births. During the whale birth process, calves will emerge fins first.
What is the similarity between breathing in human and whales?
A whale’s lungs work like ours do, but they make the most of each breath. In one breath, a humans body can absorb about 15 percent of the oxygen inhaled. The whale, on the other hand, absorbs as much as 90 percent of the oxygen it breathes in.
How do whales sleep without breathing?
Scientists believe they sleep with one eye open and one half of their brain awake, not only to control their breathing but also to ensure they can avoid predators, maintain social contact or continue swimming.
How do whales sleep and breathe?
So whales can sleep literally with one eye open. (plus one brain hemisphere ‘awake’) to remember to breathe. Or if able to, they can hold there breaths for such long times that they can sleep between breaths.
How do whales take in carbon dioxide?
The carbon capture potential of whales is truly startling. Whales accumulate carbon in their bodies during their long lives. When they die, they sink to the bottom of the ocean; each great whale sequesters 33 tons of CO2 on average, taking that carbon out of the atmosphere for centuries.
How can whales breathe so fast?
This is possible because their lungs have a large surface area to rapidly exchange gases. This surface area comes from all of the small alveolar sacs in the lungs at the end of the larger airways that come in contact with the fresh oxygen.
How is whale sperm extracted?
Spermaceti processing After killing a sperm whale, the whalers would pull the carcass alongside the ship, cut off the head and pull it on deck. Then, they would cut a hole in it and bail out the matter inside with a bucket. The harvested matter, raw spermaceti, was stored in casks to be processed back on land.
How do killer whales breastfeed?
To be more hydrodynamic, the mother’s nipples are inverted at the mammary gland until the baby starts to nudge where they then start to point out. The mom then starts to shoot out milk. Whales don’t have lips, so they can’t really suckle the milk. Instead it’s almost injected into the baby’s mouth.
