Bowhead whale: over 200 years old

Bowhead whales are the longest-lived mammals, living in the Arctic and sub-Arctic regions. In May 2007, researchers captured a sample of a bowhead whale off the coast of Alaska and found a harpoon made from 1879 to 1885 on its neck. Based on this, it is inferred that the age of death is between 1 15 and 130.

Aleutian islands: over 200 years old.

Aleutian flounder is one of the longest-lived fish, and the longest-lived fish can live to 205 years old. These pink or brown fish live in the Pacific Ocean from California to Japan. The Canadian Committee on Endangered Wildlife (COSEWIC) estimates that they will grow to 38 inches (97 cm) long and feed on other animals such as shrimp and small fish.

Freshwater pearl mussels: over 250 years old

Freshwater pearl mussel is a kind of bivalve, which mainly lives in rivers and streams in Europe and North America. According to the World Wildlife Fund (WWF), the oldest known freshwater pearl mussel is 280 years old. These invertebrates live a long life because of their slow metabolism.

Greenland sharks: over 272 years old

Greenland sharks live in the depths of the Arctic and the North Atlantic, and are one of the largest shark species in existence. According to the data from the Shark Observatory in St Lawrence, Canada, they can grow to 7.3 meters long and feed on marine mammals such as fish and seals.

Deep-sea tube worms: over 300 years old

Deep in the cold ocean is a very magical world. There are not only many creatures that are difficult for ordinary people to see, but also some of them have amazing life characteristics. A tubular worm called Escarpia laminata is the best one.

Arctic clam: over 500 years old

Arctic clams inhabit the North Atlantic. In 2006, scientists captured an Arctic clam off the coast of Iceland, but it died unexpectedly in the follow-up study. 20 13, 165438+ 10 month, 13, the analysis released by scientists shows that the real age of this arctic clam is as high as 507 years old. This means that it was born around 1499. In view of this, scientists named this Arctic clam after the Ming Dynasty in China.

Black horned coral: over 4000 years old.

Corals look like colorful underwater rocks and plants, but in fact they are composed of exoskeletons of invertebrate corals. These corals will continue to reproduce and create a genetically identical copy to replace themselves. With the passage of time, the structure of coral exoskeleton becomes larger and larger.

Glass sponge: over 10000 years old.

Similar to corals, glass sponges are composed of animal communities and can survive for thousands of years. It is one of the longest-lived sponges on earth. According to the National Oceanic and Atmospheric Administration (NOAA), they mainly live in the deep sea, hence the name, because their bones are similar to glass. A study published in Chemical Geology in 20 12 estimated that a glass sponge had existed for 1 1000 years.

Lighthouse jellyfish: Still immortal

Lighthouse jellyfish are also called immortal jellyfish because they may live forever. Jellyfish begin their life as larvae, then settle on the bottom of the sea and become corals, and then these corals will give birth to free-swimming jellyfish. According to the American Museum of Natural History, mature lighthouse jellyfish are special in that if they are physically injured or hungry, they can turn back into corals and then become jellyfish.

Hydra: Or eternal life.

Hydra is a creature that lives between jellyfish and coral in fresh water. These invertebrates are mainly composed of stem cells, which can be regenerated continuously through replication or cloning, which gives hydra super regenerative ability. It takes only a short part of the body to regenerate and grow the whole body in a few days.
