giant dragonflies refer to dragonflies larger than common dragonflies. Some scientists have studied that giant dragonflies with a wingspan of 1m appeared on the earth 300 million years ago, and now the dragonflies with a wingspan of 15cm in Australia are also called giant dragonflies.
10. Ancient centipede
The ancient centipede lived in the Carboniferous period and became extinct in the Permian period 300 million years ago. The body length can reach 8.6 feet (about 2.59 meters). The shape is similar to the modern centipede. It looks terrible and has a huge body. Fortunately, this animal lived more than 300 million years ago, and now it will never suddenly appear around anyone. The ancient centipede lived in the Carboniferous period and became extinct in the Permian period 300 million years ago.
9. Giant clam
Introduction giant clam, also known as giant clam, belongs to curtain clam order and Mako clam family mollusk. It is about 1.2m long and weighs more than 227kg. Its service life in field environment can reach more than 100 years. It is a kind of mollusk that lives in the ocean and is the largest mollusk on earth.
8. Peruvian giant centipede
Introduction the giant centipede of Peru, with a maximum of 41-42cm. The first pair of feet of the centipede are hooked and sharp. The mouth of the toxic gland at the hook end is generally called palatal teeth, tooth claws or toxic limbs, which can discharge venom. It is mainly distributed in Trinidad island in the Caribbean and Amazon countries and regions such as Peru, Ecuador and Brazil in South America.
7. Angle stone
Cameroceras is an extinct cephalopod living in Devonian. The huge corner stone is about 30 feet (9 meters) long, but the accuracy of this estimate is still controversial. Even so, Hornets are still one of the greatest creatures of the Paleozoic. From its huge body, it is speculated that the hornstone is a top predator living in the deep sea (they may not be able to move their bodies in the shallow sea), and may feed on the wide winged Limulus (such as the giant feather winged Limulus).
6. Land killer scorpion
Introduction land killer scorpion is another ancient scorpion species. They live on land and can reach 60 cm in length. They lived in the Devonian period about 400 million years ago. It is likely that they feed on small arthropods and insects. Its sting is enough to kill some animals.
5. Giant sea scorpion
Paleontology was once a behemoth among arthropods on earth. It often lurks in shallow water, looking for fish, trilobites and other animals in the sediment, and sometimes even the same kind. In about 10 million years of marine life, this guy waving a pair of giant claws can be regarded as a overlord. Early marine vertebrates simply did not pose a threat to it!
4. Giant snail
Introduction African giant snail (scientific name: Achatina Fulica) is a medium and large terrestrial snail. The length of adult shell is generally 7 ~ 8 cm, and the maximum can be more than 20 cm. Nocturnal, omnivorous, mostly active in humid environment, like to haunt in rain and at night. Usually hide in a cool place, and make a layer of white film (false mouth cover) on the shell. There is only one small hole to breathe. Shrink the snail meat into the shell to prevent dehydration. Wait until the environment improves.
3. Giant Dragonfly
Introduction giant dragonflies refer to dragonflies with larger body size than common dragonflies. Some scientists have studied that giant dragonflies with a wingspan of 1 meter appeared on the earth 300 million years ago. Now the dragonflies with a wingspan of 15 cm in Australia are also called giant dragonflies.
2. Giant Limulus
It has strong protection - covered with ridges, claws and armor. They walk on six legs and have two flat paddle like legs behind them. Once they leave the water, they will be clumsy. If you are underwater, you can swim a distance. They are usually sea dwellers, but they can also live in fresh water and on land. Giant feather winged Limulus roams the seabed, looking for trilobites and other animals living in sand and mud. It also eats its own kind. Giant feather winged Limulus can only grow by molting. Just after molting, he and his companions gathered in shallow water to seek quantitative safety. During molting, it uses its temporary soft body and a large number of neighbors to mate.
It is found that the giant feather winged Limulus is similar to that of arthropleuria, except that the former lives in the ocean. This' Sea Scorpion '(just like a scorpion in shape) is more than 8 feet long and lived 390 million years ago.
1. Giant shrimp
Introduction giant shrimp is a very strange ancient creature. It has the characteristics of squid and shrimp. Its body length is up to 1m and its mouth is full of sharp teeth. The fossil of giant shrimp was found in China. It is an ancient underwater arthropod that lived about 500 million years ago.
