Ichthyosaurs appeared about 250 million years ago. They are marine reptiles dinosaurus. They are also fish. They are an excellent example of evolution, as there is evidence of similar structure between them and sharks. Ichthyosaur species were sorted by size. Their bodies were slender and muscular. Pectoral fins evolved from the limbs of their four-legged predecessors, such as the shark. They had a triangular dorsal fin that stabilized them in the water. Remains of ichthyosaurs with embias have been found, proving that they gave birth to live cubs. Thanks to its large eyes, the ichthyosaur species was excellent, even in muddy water. Their skulls were elongated and triangular. They had several rows of tiny teeth. Ichthyosaurs were probably carnivores that ate fish.

Meadow viper is a snake that loves to sunbathe and always does&nbsp; so that it curls up in a circle on some hot rock or grass.&nbsp; &nbsp;It is considered the smallest European snake because it most often does not grow more than 50cm which is quite short for a snake specimen. These snakes&nbsp; &nbsp;are shorter than other snakes. The meadow viper is a snake that inhabits grasslands, and the largest number of specimens can be found at&nbsp; grasslands of mountainous areas. Although it is able to hunt small mammals, but lizards are mostly satisfied with locusts and smaller ones&nbsp; Animals. The poison it stores in its glands is not strong so this is one of the milder types of poison. The bite is not dangerous to humans and in general&nbsp; causes mild inflammation at the site of the bite, but can be very painful. Sometimes&nbsp;vomiting and nausea may also occur, but this is quite rare&nbsp; complication, mostly present in more sensitive people.&nbsp;

This animal is black and white, there are only between 500 and 1890 adult specimens left in the wild, but there are already many more young individuals and there are even more in captivity, under the care of specialists who have dedicated themselves to their recovery. The panda, with its distinctive black and white coat, is adored by the world and considered a national treasure in China. This bear also has a special significance for WWF because it has been our logo since our founding in 1961. Pandas live mainly in temperate forests high in the mountains of southwest China, where they subsist almost entirely on bamboo. They must eat around 26 to 84 pounds of it every day, depending on what part of the bamboo they are eating. They use their enlarged wrist bones that function as opposable thumbs.

Black rhinos are the smaller of the two African rhino species. The most notable difference between white and black rhinos are their hooked upper lip. This distinguishes them from the white rhino, which has a square lip. Black rhinos are browsers rather than grazers, and their pointed lip helps them feed on leaves from bushes and trees. They have two horns, and occasionally a third, small posterior horn.

The white tigers are distinctive due to the color of their fur. The white fur caused by a lack of the pigment&nbsp;melanin, which is found in Bengal tigers with orange color fur. When compared to Bengal tigers, the white Bengal tigers tend to grow faster and heavier than the orange Bengal tiger. They also tend to be somewhat bigger at birth, and as fully grown adults. White Bengal tigers are fully grown when they are 2–3 years of age. White male tigers reach weights of 200 to 230 kilograms and can grow up to 3 meters in length. As with all tigers, the white Bengal tiger’s stripes are like fingerprints, with no two tigers having the same pattern. The stripes of the tiger are a pigmentation of the skin; if an individual were to be shaved, its distinctive coat pattern would still be visible.

Lions are the only large cats that live in a group called a pack and there can be up to 30 of them. The big male protects the territories of his pack. He also defends his females from all other males. Lions and other large cats have short, firm skulls with strong jaws. Their teeth, like spears, pierce and tear the flesh of the victim. By opening and closing the jaws, large molars tear and grind the meat. Lions and other big cats are real carnivores. Lions usually attack large prey such as antelopes or zebras. One giraffe is enough to feed an entire pack. When a cat falls on a victim or climbs a tree, it stretches out its sharp claws. The muscles in the paw push out their claws and pull back their pillow protectors. Most of the time cats are claws protected in muscle pads. This keeps the claws sharp and prevents them from breaking. When the cat cleans its paws, its claws are outstretched.
