The longest-lived vertebrate animals ranked by maximum verified lifespan — from the Greenland shark to the bowhead whale.
Quick answer: 1. Greenland Shark (Somniosus microcephalus), 2. Bowhead Whale (Balaena mysticetus), 3. Rougheye Rockfish (Sebastes aleutianus), 4. Lake Sturgeon (Acipenser fulvescens), 5. Aldabra Giant Tortoise (Aldabrachelys gigantea), 6. Shortraker Rockfish (Sebastes borealis), 7. Galápagos Giant Tortoise (Chelonoidis niger), 8. Koi Fish (Cyprinus rubrofuscus), 9. Longfin Eel (Anguilla dieffenbachii), 10. African Elephant (Loxodonta africana).
Vertebrates — animals with backbones — include some of the longest-lived creatures on Earth. This list focuses exclusively on vertebrates (fish, amphibians, reptiles, birds, mammals), setting aside the truly immortal invertebrates like hydra and certain jellyfish that belong on a separate list. The ages here are maximum verified lifespans from scientific studies, not typical life expectancies. Some figures were determined through radiocarbon dating of eye lenses or growth rings, especially in deep-sea fish and cold-water species that age far slower than their warm-water counterparts.
The Greenland shark is the longest-living vertebrate on Earth. Radiocarbon dating of eye lens proteins has yielded estimated ages of 250–500 years, with one specimen estimated at 392 ± 120 years.
Bowhead whales are the longest-living mammals. Evidence includes recovered stone harpoon tips embedded in blubber and eye lens aging studies suggesting lifespans over 200 years.
The rougheye rockfish inhabits deep North Pacific waters and grows very slowly. Its age is determined by counting growth rings in otoliths (ear bones), with the oldest recorded at 205 years.
Lake sturgeon are among the longest-living freshwater fish. The oldest recorded specimen was estimated at 152 years old.
The Aldabra giant tortoise is one of the longest-living reptiles. The most famous individual, Jonathan, lives on Saint Helena and was born around 1832, making him over 190 years old.
The shortraker rockfish is another deep-dwelling Alaskan rockfish with remarkable longevity. The oldest recorded specimen was 157 years old, though ages over 120 are more commonly observed.
Galápagos giant tortoises regularly live past 100 years. The oldest known individual, Harriet, died in 2006 at an estimated age of 175 in captivity.
Koi, a domesticated variety of the Amur carp, have been known to live for over a century. The oldest verified koi, Hanako, died in 1977 at an estimated age of 226 (though this is debated; verified centenarian koi are well-documented).
The New Zealand longfin eel is one of the longest-living freshwater eels. Females can live to 100 years or more in remote New Zealand waterways before migrating to the ocean to spawn.
African elephants are the longest-living land mammals, with maximum lifespans of 60–70 years in the wild. The oldest known elephant lived to 86 in captivity.
| # | Name | Class | Habitat | Method of age estimation | Typical adult size |
|---|---|---|---|---|---|
| 1 | Greenland Shark (Somniosus microcephalus) | Fish | North Atlantic / Arctic | Radiocarbon dating of eye lens | 4–6 m |
| 2 | Bowhead Whale (Balaena mysticetus) | Mammal | Arctic | Harpoon artifact analysis, aspartic acid racemization | 14–18 m |
| 3 | Rougheye Rockfish (Sebastes aleutianus) | Fish | North Pacific | Otolith growth ring count | 40–60 cm |
| 4 | Lake Sturgeon (Acipenser fulvescens) | Fish | North American freshwater | Fin ray and otolith analysis | 1–2.5 m |
| 5 | Aldabra Giant Tortoise (Aldabrachelys gigantea) | Reptile | Aldabra Atoll, Seychelles (sub-Saharan Africa) | Direct observation (birth record) | 100–120 cm shell length |
| 6 | Shortraker Rockfish (Sebastes borealis) | Fish | North Pacific | Otolith growth ring count | 50–80 cm |
| 7 | Galápagos Giant Tortoise (Chelonoidis niger) | Reptile | Galápagos Islands | Direct observation + historical records | 120–150 cm shell length |
| 8 | Koi Fish (Cyprinus rubrofuscus) | Fish | Freshwater ponds (Japan) | Scale growth ring analysis | 60–90 cm |
| 9 | Longfin Eel (Anguilla dieffenbachii) | Fish | New Zealand freshwaters | Otolith growth ring analysis | 1–2 m |
| 10 | African Elephant (Loxodonta africana) | Mammal | Sub-Saharan Africa | Direct observation | 3–4 m shoulder height |
Vertebrates are ranked by maximum verified lifespan in years, drawn from peer-reviewed scientific literature and authoritative databases. Ages marked with an asterisk (*) were determined via radiocarbon dating or other indirect methods, as direct observation over the full lifespan was impossible. Where multiple sources disagree, the most conservative widely accepted figure is used.
The Greenland shark is the longest-living vertebrate, with radiocarbon-dated ages of up to 392 years (±120 years).
Scientists use radiocarbon dating of proteins in the shark's eye lens, which forms before birth and remains metabolically inert throughout life.
The Aldabra giant tortoise holds the record for land vertebrates, with the oldest known individual (Jonathan) living to over 190 years.
