Ten Living Fossils of Animals and Plants

gabrin Shark

It is a very special and fierce man-eating shark fish, which often moves in the deep sea. The gray fish skin is shiny with metal, and it looks very ugly and fierce. Its lips and kisses are longer than those of fierce and cruel tiger sharks, and its sharp teeth are just like an upright triangular knife, with cold light flashing, which makes people shudder.

The shark in gabrin has an unyielding backbone. It doesn't want to be captured alive, but would rather be smashed to pieces. When it is trapped in a fishing net, it will expand through the change of the body pressure of its own swim bladder, and finally explode into large and small pieces by itself, so until now, no country in the world has caught a complete gabrin shark. Therefore, it is impossible to make a breakthrough in the study of sharks in gabrin. What people usually see is just fragments of devil sharks, and the fractures are uneven, much like the broken bricks or porcelain. Their thick skin has little toughness and elasticity, especially fish skin is as hard as ceramic products. After the explosion, the devil shark piece is like a piece of porcelain that we usually break, and the fractures can be spliced together exactly.

lizard

lizard is the only reptile known to have survived the dinosaur era on earth, and its number is already very rare. However, due to global warming, this big lizard, known as the living fossil of New Zealand, is facing the danger of extinction. Studies have shown that the increase in temperature has greatly increased the male proportion of large lizards, and may eventually become extinct because of the lack of females.

sea lilies

Sea lilies are echinoderms that began in the Carboniferous. They live in the sea, have many brachiopods, have a flower-shaped body and a calcareous shell on the surface. Because they look like plants, people give them the name of sea lilies. The body of sea lilies has a stalk like a plant stem, and the pinnate thing at the upper end of the stalk is their tentacles, also called wrists. These tentacles confuse people into thinking that they are plants just like fern leaves. Sea lily is an ancient invertebrate. Hundreds of millions of years ago, they were everywhere in the ocean.

monkey fan tree

monkey fan tree, also known as "Chilean pine", is an ancient coniferous tree. This tree has strange scaly branches (actually leaves) and its bark is very different, similar to the skin of reptiles. This kind of tree has weird scaly branches (actually leaves) and its bark is very different, similar to the skin of reptiles. The monkey fan tree is hard, with a height of 13 feet (about 4 meters) and a diameter of 6 feet (about 1.8 meters).

coelacanth

coelacanth is one of the oldest fishes in the world, and is usually regarded as a living fossil. It was once thought to have been extinct as early as 65 million years ago, but it was discovered by humans in 1938. Since then, coelacanth has been called "the living fossil of the dinosaur era".

ponytail

ponytail, a equisetum plant, is a unique plant that breeds the next generation through spores instead of seeds.

Horseshoe Crab

Horseshoe crab is actually not a real crab, but a primitive arthropod. They have broad disc-shaped bodies and slender needle-shaped tails. Their ancestors can be traced back to the CAMBRIAN period, but it was not until the Jurassic period that the appearance of horseshoes was exhibited. Although there are still five species of horseshoe crabs, they have been less common since the late Cretaceous.

platypus

platypus is a world-famous rare animal, which is produced in southern Australia and Tasmania and is one of the most primitive mammals in existence. Its tail is flat and wide, and its front and rear limbs are webbed and clawed, which is suitable for swimming and digging. The platypus burrows near the water and feeds on worms, aquatic insects and snails. When breeding, the female platypus lays two eggs at a time, and the cubs lick the milk from the wet hair on the mother's abdomen.

Nautilus

Nautilus, Latin name: Nautilus Pompiplius, English name: Ammonite, family and genus classification: Cephalopoda, Tetrabranchia, Nautilus, belonging to mollusks and shellfish. Nautilus is basically a benthic animal, which usually crawls slowly with its wrists at the bottom of 1 meters deep water. You can also use the secretion of the wrist to attach to rocks or coral reefs. They can swim in the water by means of inflatable shells, or "rush back" by spraying water from funnels. After the storm, on a calm night at sea, Nautilus floats comfortably on the sea surface, with its shell up, its mouth down and its head and wrist fully extended. These animals are nocturnal, and their main food is benthic crustaceans, especially small crabs.

musk pheasant

musk pheasant, which lives in tropical South America, has a crest. Adult birds are about 22 inches (56 cm) long. The upper body feathers are brown with white spots. The lower body and feather crest are reddish brown. The naked skin on the face is blue. Musk pheasant was born with two claws on each wing for climbing. After three weeks, these two claws disappeared. Musk pheasant crop is huge and divided into two parts, which is used to store and digest the elastic leaves of Alocasia, which is its main food source. Musk pheasant is called a stinkbird because it has a strong musty smell in its body. Open classification:
