The biggest shark in that study was estimated to be about 392 years old, and the researchers suggested that the sharks could have been up to 512 years old, Live Science previously reported. Lawrence Shark Observatory in Canada.Ī 2016 study of Greenland shark eye tissue, published in the journal Science, estimated that these sharks can have a maximum life span of at least 272 years. They can grow to be 24 feet (7.3 meters) long and have a diet that includes a variety of other animals, including fish and marine mammals such as seals, according to the St. Greenland sharks ( Somniosus microcephalus) live deep in the Arctic and North Atlantic oceans.

A longer life span allows the rockfish to grow larger and produce more young. They grow up to 38 inches (97 centimeters) long and eat other animals, such as shrimp and smaller fish, according to the Committee on the Status of Endangered Wildlife in Canada, an independent advisory panel that assesses the statuses of species threatened with extinction in Canada.Ī 2021 study published in the journal Science looked at the genomes of 88 rockfish species, including rougheye rockfish, and found genetic calling cards for longevity, including DNA repair pathways that may help ward off cancers.
These pink or brownish fish live in the Pacific Ocean from California to Japan. The rougheye rockfish ( Sebastes aleutianus) is one of the longest-living fish, with a maximum life span of at least 205 years, according to the Washington Department of Fish and Wildlife.

"My own view is that different long-lived species use different tricks to evolve long life spans, and there aren't many genes in common," João Pedro de Magalhães, an expert in aging science at the University of Birmingham in the U.K., previously told Live Science.

Studying these long-lived whales could provide hints about how to prolong human life. This gene is involved in cell growth and repair, and the duplication could slow aging, Live Science previously reported. Furthermore, another gene, called PCNA, has a section that has been duplicated. The whales have mutations in a gene called ERCC1, which is involved with repairing damaged DNA, that may help protect the whales from cancer, a potential cause of death. The Arctic and sub-Arctic whales' exact life span is unknown, but stone harpoon tips found in some harvested individuals prove that they comfortably live over 100 years and may live more than 200 years, according to the National Oceanic and Atmospheric Administration (NOAA).

The red sea urchins found off Washington and Alaska probably live more than 100 years, and the longest-living individuals in British Columbia, Canada, may be around 200 years old, according to a 2003 study published in the journal Fishery Bulletin. Researchers used to assume that red sea urchins grew quickly and had modest life spans of up to about 10 years, but as scientists studied the species in more detail, they realized these urchins continue to grow very slowly and, in some locations, will survive for centuries if they can avoid predators, disease and fishers. They live in shallow coastal waters off North America from California to Alaska, where they feed on marine plants, according to Oregon State University. Red sea urchins ( Strongylocentrotus franciscanus) are small, round invertebrates covered in spines.
