You know my methods, Watson. There is an amusing twist on this theme. While it is certainly true that larger species tend to live longer, on average, it is also true that within a species, smaller individuals often live longer than bigger individuals.
Perhaps it comes down once again to metabolic rate: larger individuals need a higher metabolism to keep up their energy levels, so perhaps they tend to clock through their allotted times a bit quicker??
The longest living mammal is the bowhead whale, which can live up to years. Also known as the Arctic whale, this animal is big, and lives in cold waters so its metabolism is slow. The record age for a bowhead is years. Want to keep learning? See other articles from this course. This article is from the online course:. Join Now. News categories.

According to a study utilizing eye lens radiocarbon testing, the minimum life span of a Greenland shark is years, with a maximum reported age of years. The authors of the study concluded that the Greenland shark is the longest-living vertebrae known to man. The Greenland shark lives in the Arctic and North Atlantic waters at depths averaging from 4, to over 7, feet.
This shark grows slowly to a length of 8 to 14 feet at maturity. It scavenges for its food and eats a variety of fish and birds. These oversized saltwater clams have been known to live for more than years. Geoducks experience rapid growth during their first years of life, growing an average of over 1 inch per year in the first four years.
Characterized by their long "necks," or siphons, the body of a geoduck can grow to more than 3 feet in length, while the shell is typically no longer than 8 inches. Geoducks are native to the Pacific Northwest from California to Alaska. Tuatara are the only surviving members of an order that flourished about million years ago, the Sphenodontia. Considered living fossils , tuatara are among the longest-lived vertebrates on Earth, with some individuals living over years.
Found only in New Zealand, tuataras reach sexual maturity after 10 to 20 years and continue growing until they are 35 to 40 years old. These colorful deep sea creatures are tube worms Lamellibrachia luymesi that have been known to live between and years. These vestimentiferan tube worms live along hydrocarbon cold seep vents on the ocean floor. The Lamellibrachia is unique among vent creatures because it grows slowly throughout the duration of its life to a length of over 6 feet.
This creature is found in the Atlantic Ocean, especially in shallow portions of the Gulf of Mexico basin. The red sea urchin Strongylocentrotus franciscanus has a life expectancy from to over years.
Found only in the Pacific Ocean, primarily along the West Coast of North America and the northern coast of Japan, the red sea urchin lives in shallow, sometimes rocky waters. The red sea urchin avoids extremely wavy areas and stays primarily from the low-tide line down to feet. A European brown bear in the Carparthian Mountains, Romania.
Lowland tapirs can live for up to 30 years. This baby gorilla has a lifespan of around 35 years. This would make him the world's oldest living land animal, but there are no records to prove his age so the Guinness Book of World Recordsawards that distinction to an year-old tortoise in the Seychelles Islands named Jonathan.
Fish aren't known for their long lifespans, but Japanese Koi Fish can live up to 40 years or longer if they are kept in the right conditions. Koi fish are descended from the common carp and modern Japanese koi are believed to date back to early 19th-century Japan where wild, colorful carp were caught and bred by rice farmers.
Bowhead whales, found in the Arctic, are believed to be among the longest-lived animals on earth. According to the World Wildlife Fund, the analysis of eye tissue and stone harpoon tips found in their blubber, bowhead whales can live for more than years.
The Greenland shark has the longest known life span of all vertebrates, estimated to be between and years. Found in the North Atlantic and Arctic Oceans, the species can reach an astonishing 21 feet in length and mostly eats fish, but has been spotted hunting seals. In the wild, gorillas live for 30 or 40 years and in some cases can reach There are two species of gorilla—the eastern and western.
Each of these is divided into two subspecies: the eastern lowland gorilla and the mountain gorilla, and the western lowland gorilla and the cross river gorilla. According to WWF, humans share
