Creatures that have lived for hundreds of millions of years, do you know where they live?

The first is the giant panda. Giant pandas live in China, followed by creatures that have lived for hundreds of millions of years at the bottom of the deep sea. The living environment there is very harsh, so they can survive undisturbed.

I know. They live in unknown places. Generally very precipitous and peculiar places, places that ordinary people cannot reach.

There is a creature that has been around since the Cambrian period, and until now, it is a horseshoe crab, and they usually live in the dirt.

Soxhlet Peach Jellyfish: The Soxhlet Peach Jellyfish is a small jellyfish that lives in freshwater areas (i.e., living in rivers, rivers and lakes), they are very small, about 15-25 mm in diameter, and 11 species have been recorded, and Soxhlet Peach Jellyfish is one of them.

Nautilus : Nautilus is basically benthic and usually crawls slowly on the bottom of 100 meters of deep water with its wrist.

Sponge: Sponge is the most primitive multicellular animal, which has lived in the ocean 600 million years ago and has developed to more than 10,000 species.

There is no such concept as eontible years ago, which is a unit a long time ago, and paleontologists tell us that about 3.6 billion years ago, the first living cells were created.

1. The Archean is the oldest period of geohistory, from the perspective of the biological world, this is the primary stage of primitive life and biological evolution, when there were only a small number of prokaryotes, and they only left a very small fossil record.

2. With the increasing prosperity of plants and the continuous strengthening of photosynthesis in the Proterozoic, the oxygen content of the atmosphere continued to increase, and the algae plants in the middle and late stages of the Yuanxingwang period were very prosperous, which was obviously different from the ancient Liang sock generation.

3. The most prominent feature of the Sinian biological world is that there are many kinds of non-hard-shelled metazoans in the later period, and a small number of small shells appear in the late stage.

1. Plants mainly include algae plants, bryophytes, ferns, gymnosperms such as pine, cypress, cedar, etc.;

2. Animals mainly include single-celled animals, porous animals such as sponges, nematodes such as nematodes and roundworms, flattened key-burning animals such as planarians and tapeworms, neomorphs such as carbs and neoworms, echinoderms such as starfish, coelenterates such as polyps and sea stingers, annelids such as earthworms, molluscs such as squid, snails, shellfish, snails, arthropods such as insects, shrimps and crabs, vertebrates such as fish, amphibians, reptiles, and the original mammals;

3. There are all kinds of microorganisms in existence, such as bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, and spirochetes.
