1, lighthouse jellyfish
This jellyfish may be the only one found in the world that can live forever in theory, because lighthouse jellyfish can reproduce asexually from hydra, and ordinary jellyfish will die after sexual reproduction, but lighthouse jellyfish can return to hydra again and circulate indefinitely.
2. coral
There are many kinds of corals, more than 7000 kinds. Coral is shaped like a branch and rich in color, so it is often used as an ornament. At present, the maximum life span of corals found in the world is about 4,200 years old, and they live in the sea floor 1246 meters deep.
3.anemones
Anemone is a very simple animal and doesn't even have a brain. It looks like a flower, but it is actually a carnivore living in the sea, and its tentacles can also release toxic substances. Scientists have determined that its age can reach 1500 to 2 100 years old.
4. Antarctic sponge
Perhaps it is because of the extremely low temperature in the Antarctic ocean that this motionless creature grows very slowly. It can be motionless for decades, and the life span of the oldest specimen owned by human beings reaches 1 550 years. Longer than turtles and corals. It is one of the top ten marine life with the longest life.
5.clam
Round clam is one of the most important edible clams along the Atlantic coast. Researchers regard the black on the shell as a ring mark, just like the ring in the heart of a tree, representing its life. The oldest known clam in the world is over 500 years old. It is one of the longest-lived marine life in the ten oceans.
6. Greenland sharks
This kind of shark lives in Arctic waters, and its average length can reach 65,438+06 feet. It usually lives in the deep sea. Scientists have conducted radiocarbon tests on the eyeballs of 28 female sharks, and determined that their life span is at least 272 years. It is speculated that their longest life span may exceed 400 years. Greenland sharks are the longest-lived vertebrates known to man.
7. Tube worms
Tube worms are colorful deep-sea creatures. Their tops are red and their bottoms are straight white tubes, so the famous tube worms look like flowers with white stems and red flowers. They usually live in hydrocarbon vents on the seabed. According to scientists' research, the tube worm may have lived to be 250 years old.
8, giant ball purple sea urchin
This giant purple sea urchin likes marine life living in shallow water, especially staying on sheltered rocks or beaches. Generally, they are relatively small, and their bodies grow up slowly with age. Scientists have studied that some giant purple sea urchins have a life span of more than 200 years.
9.bowhead whale
The bowhead whale, also known as the Arctic whale, is by far the longest-lived mammal on earth. It has been found that some bowhead whales have traces of ivory spear points left after a failed whaling 200 years ago. The oldest known whale is at least 2 1 1 year old.
10, tortoise
Turtles generally live in the Atlantic Ocean, the Pacific Ocean and the Indian Ocean, and only in the breeding season will they go ashore and lay eggs on land. Turtles evolved into fins to adapt to life in the sea. The longest turtle can grow to more than 1 m, and the longest life span is generally around 150.
