What Is a Dolphin's Life Span? Lifespan Details. A dolphin's life span varies according to its environment and species. Although some bottlenose dolphins can reach 40 years of age, their average age is between 15 and 16 years. Forty is an old age for a dolphin -- one making it to 40 is comparable to a human living to be 100.

- 8 The Life Span of a Dolphin. The life span of a dolphin is believed to be about 20 years. Some people have proven that dolphins can live up to 48 years. Without a calculator or a degree in marine biology, that pretty much means the Miami Dolphins will win the Superbowl in destructive fashion this year.

They band together in social groups called pods, and hunt for food such as squid or schools of smaller fish.

- In most cases a dolphin will stay with the group it was born in, even after it reaches maturity. This is usually the mother’s group. As part of the dolphin life cycle it will reach sexual maturity at about 7 to 12 years of age for a female and 10 to 15 years of age for a male.

7 Animals With Incredibly Long Life Spans 7 Animals With Incredibly Long Life Spans. Human longevity is increasing all the time. But compared to some other animals, a human's average life span (about 78.5 years according to the CDC) is nothing to brag about. One bird just celebrated his 79th birthday, and a certain reptile became a father for the first time at age 111.

River dolphin Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae, Platanistidae, Iniidae, and Pontoporiidae, and the extinct Lipotidae. There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Cetaceans' closest living re

SeaWorld Tries to Convince You That Keeping Orcas is Ethical Claim #3: SeaWorld’s killer whales’ life spans are equivalent with those in the wild. SeaWorld argues that the life spans of its captive orcas are “comparable” to those in the wild, stating that five of its orcas are older than 30, with one being close to 50.

- Animals With Long Life Spans. Average Life Span: Over 200 Years One hundred may be old for humans -- and tortoises -- but it's nothing for the bowhead whale. In fact, he's only middle-aged at that point in his astoundingly long life. This species of whale can live for over 200 years.

Physical Characteristics A dolphin’s skin is smooth and feels rubbery. The skin has no hair or sweat glands. The outer skin layer (epidermis) is about 10 to 20 times thicker than the epidermis of terrestrial mammals. Just like human skin, dolphin skin constantly flakes and peels as new skin cells replace old cells. A bottlenose dolphin's outermost skin layer may be replaced every two hours. This sloughing rate is nine times faster than in humans. This turnover rate ensures a smooth body surface and probably helps increase swimming efficiency by reducing drag (resistance to movement).

Facts about dolphins For the dolphin population in Sarasota Bay, the ASR has been measured to be about 0.961. This yields a life expectancy of about 25 years. For the population in the Indian/Banana River area, the ASR is between 0.908 and 0.931. This yields a life expectance between 10.3 and 14 years.

Tursiops truncatus bottlenosed dolphin Gestation lasts about 12 months and each pregnancy produces one calf. Females nurse their young from nipples on each side of their genital slit until the calf is between 18 and 20 months. Bottlenosed dolphins reproduce every 3 to 6 years, with females usually becoming pregnant soon after their calf is weaned.

How Are Dolphins and Porpoises Different? While most porpoises only live 15 to 20 years, dolphins can live up to 50 years or more. Scientists believe this difference may be caused by the fact that porpoises reproduce faster than dolphins and it takes a toll on their bodies. One last difference to note is that dolphins produce sounds that humans can hear. Many people have seen firsthand how “talkative” dolphins can be. Porpoises, on the other hand, make sounds that humans cannot hear.
