Creatures in the water live long lives! List of top animals

Bowhead whales: 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 head on its neck that had been manufactured between 1879 and 1885, which led to an estimate of its age at death of between Between 115 and 130 years old

Aleutian flatfish: over 200 years old

Aleutian flatfish are one of the longest-lived fish, with the longest-lived living up to 205 years old. These pink or brown fish live in the Pacific Ocean from California to Japan. The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assesses that they grow to 38 inches (97 centimeters) long and feed on other animals such as shrimp and small fish

Freshwater pearl mussels: 250 years old or older

Freshwater pearl mussels are a type of bivalve that live mainly 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, and these invertebrates are long-lived due to their slow metabolisms

Greenland sharks: 272 years old or older

Greenland sharks, which live in the Arctic and deep in the North Atlantic Ocean, are one of the largest surviving shark species. According to Canada's St. Lawrence Shark Observatory, they can grow up to 7.3 meters in length and feed on marine mammals such as fish and seals

Deep-sea tubeworms: more than 300 years old

The frigid depths of the oceans are a magical world, home to a host of creatures that are not easy for people to see, and some of which have amazing life features. A tubular worm called Escarpia laminata is one of them

Arctic clams: over 500 years old

Arctic clams inhabit the North Atlantic, and in 2006, scientists caught one off the coast of Iceland, but it died during a follow-up study. on November 13, 2013, scientists released an analysis showing that the real age of the clam was as high as 507 years old. This means that it was born around the age of 507 years. That means it was born around 1499 A.D. In light of this, scientists named the clam after the Chinese dynasty Ming

Blackhorn coral: 4,000 years old or older

Corals may look like colorful underwater rocks and plants, but they're actually made up of the exoskeletons of invertebrate coral polyps. assembled. These coral polyps reproduce and create a genetically identical copy to replace themselves. Over time, the coral exoskeleton structures become larger and larger

Glass sponge: 10,000 years old or older

Similar to coral, the glass sponge consists of a community of animals that can survive for thousands of years. It is one of the longest-lived sponges on Earth. They live mainly in the deep sea and are named for their glass-like skeletons, according to the National Oceanic and Atmospheric Administration (NOAA).A 2012 study published in the journal Chemical Geology estimated that a glass sponge had lived for 11,000 years

Lighthouse Jellyfish: may or may not be immortal

Lighthouse jellies are also known as immortal jellyfish because of their potential to live forever. live. Jellyfish begin life as larvae, then settle on the seafloor and transform into polyps, which then give birth to free-swimming jellyfish. The American Museum of Natural History says mature lighthouse jellyfish are special because if they are physically injured or starving, they can turn back into polyps and become jellyfish again

Hydrozoans: may live forever

Hydrozoans are creatures that live in freshwater somewhere between jellies and corals. These invertebrates are mainly composed of stem cells, which can be constantly regenerated through replication or cloning, giving hydroids superb regenerative capabilities. All it takes is a small section of the body, and within a few days it can regrow its entire body
