The world's most fat animals

Whales, statues, moths are three of the world's largest fat ratios, determining their survival.

According to a 1968 study conducted on 49 mammal species in the United States and Brazil, scientists deduced that blue whales, the largest animal on Earth, have the highest fat ratio among animals. mammals - more than 35%. With a weight of up to 180 tons, the fat of a blue whale easily reaches 63 tons.

Fat tissue in marine mammals plays an important role in reducing swimming friction, helping them to float, protect, insulate and store energy. In the whale family, head whale (Eubalaena) has the thickest fat layer.

"They are slow and fat, when they are jolted, their bodies will float to the surface so it is easy to recover. While most other whales sink , " said Dr. Sam Ridgway, chairman of the organization. National mammal (NMMF), the US explained.

There are three types of bull whales in the North Atlantic, North Pacific and South Ocean, which are classified as the most endangered species in the world due to hunting in the 19th century in order to get fat for soap. room, fuel for lamps and even margarine.

Walrus, also known as a trailer, has a large amount of fat.(Photo: BBC).

In the class of zooplankton, seals and walruses can be considered candidates for the title of the world's fattest animal. Their bodies are 18% fat and 44% are muscle. Newly weaned babies can achieve a high fat ratio after drinking breastmilk.

The statue of the sea, the seal seal, the Greenland seal, and the bridge with the ring may contain 50% of the fat when weaned. But this fat does not last long.

Hippopotamus has thick skin and not fat.(Photo: BBC).

The hippopotamus is known for its massive appearance but 18% of the body weighs 1.5 tons as skin. Under the skin layer 5cm thick is a relatively thin layer of fat.

Camels have a lot of fat.(Photo: BBC).

Fat is not only to keep warm, when metabolized, it provides essential water for desert animals. Camels have bumps to store nutrients and fat. These bumps can weigh up to 35 kg.

In fact, camels are quite thin because most of the body fat is focused on the tumor. In theory, hump fat reduces the rest of the body's heat, helping them to withstand the hot sun.

Some insects are considered fat compared to their size. Moths and larvae are known as fat-rich snacks of Australian aborigines.

Cossid moth larvae (Endoxyla leucomochla) are also called 20% fat witchetty larvae, while adult bogong moths have 39% fat. In Yellowstone National Park, USA, the grizzly bear eats the night worm to accumulate fat before winter comes.

Insect species in the western United States appear much in the spring. Around June, they migrate to the alpine climate where they eat wild nectar.

If the blue whale is the only mammal with the highest fat percentage, the night worm is the fattest animal in the animal world, with a fat ratio of 72% of the body when the weather comes to collect, helping them survive. at the cold winter.

"Essentially fat is the way to store the energy of migratory insects. Some species can fly more than 100 kilometers a day without eating, so they need large reserves , " said entomologist Todd. Gilligan, Ohio State University, explained.
