Videos of great white sharks voraciously devouring pitiful ocean creatures often delight animal lovers. However, the scientific community has discovered that despite being greedy, they have a very standard “body”.
Indeed, despite being called “fat” and “big”, the assassins who say no to this vegetarian movement do not harbor any individuals who are classified as “obese”.
According to research revealed, a great white shark can “eat” up to more than 30kg of whale fat at a time before getting too tired, providing enough energy to splash around in the ocean and spread terror for a month and a half. afterward.
In addition to fatty whale meat, they also have another favorite food of immature walrus babies – an abundant source of energy. Even a scientist saw that the killer had worked hard to remove 3 “babies” of walruses in a week. It is important to know that a great white shark weighs 1-2 tons, while a young walrus can weigh several pounds.
In the study, the scientists attached satellite tracking equipment to the shark’s body and then observed their buoyancy for long periods of time. This data will help estimate body weight and fat stores.
Accordingly, the liver is the largest organ in the body of sharp-toothed killers and can account for up to 28% of an adult’s weight. This is also the top place to store fat. The remaining fat is evenly distributed in the muscle. Thanks to an extremely active lifestyle, especially water sports such as speed swimming with prey, “sharks” cannot be overweight even though they eat a lot.
It can be said that they love to swim so much that an individual has the ability to swim more than 4,000km/trip. Scientists are not sure what is the great motivation that makes them work so hard, but surmise it could be the call of love (for the mating season) or foraging. Another possible reason is going “on vacation” to warmer waters when cold ocean currents enter the habitat.
A place in the Northeast Pacific Ocean is also affectionately known as the “big white cafe” because of the unusually large gathering of assassins there. They come to this place to dine, date and next create many more future “swimmers”.
In terms of survival, sharks need enough energy but not too much because of their swimming style. Because they have to constantly swim to breathe and tend to glide with the current, they don’t need too much fat to float as that would disrupt their movement habits.
Finally, these hungry assassins also have their favorite dishes and “reputable addresses” without the need for a food reviewer. A shark has returned to the same population of walruses for 26 consecutive years to eat.
They eventually live to be more than 70 years old, immune to blood fats, cancer and possibly heart attacks. That’s how we see the effects of regular swimming for health.
