The largest big animals on the planet (Part 1)

Below is a picture of 7 of the largest animals in the earth from prehistoric times. An extinct species long ago, some other species are struggling to survive.

Architeuthis Squid: A team of experts from Japan's National Science Museum captured the image of a squid about 8 meters long at a depth of nearly 1,000 meters in Japan's Bonin Islands. It was previously thought that this was a mythical animal.

Polar bear: The largest species of bear family and also the largest predator on land. Males have a mass of 400-600 kg. Many animals can reach 800 kg. The female is only half the size of a male and has an average weight of 200-300 kg. Global warming causes the polar bear habitat to shrink and scientists warn that they can become extinct by the end of the century.

Mammoths: This prehistoric animal elephant is extinct about 10 thousand years ago.

Giant white shark: The biggest predatory fish on the planet is at risk of extinction. Scientists do not know exactly how many sharks are alive, but they are studying their migratory habits to serve conservation.

Rhinoceros: It has been discovered that a white rhino weighs 2,270 kg. Rhino horns make them the target of poachers. Rhino habitats are also being narrowed by deforestation.

Hippo: The second largest mammal on Earth. The hippopotamus appears most in the Congo, but their numbers here are less than 900. Scientists predict they will become extinct by the end of the century.

Sea turtles: A sea turtle can weigh up to 90 kg or more. Their lifespan can reach 200 years. Sea turtles are ancient creatures, have lived through millions of years, long before humans began to form and live on the planet.
