How long do dolphins live? This question has been asked and answered many times over the years, but no comprehensive answer has ever been offered. Dolphins are a unique creature that remain unchanged for thousands of years from their prehistoric origins to their modern day lives. This article intends to address the question how long do dolphins live.


The bottlenose dolphin is the most popular name of marine mammal within the sub-family Cetacea. The word dolphin refers to the extinct platanist sub-family Delphinidae, also called Iniidae, Phocidae, and Lipotidae. There are only 40 presently recognized living species in this sub-family. These bottlenose dolphins live all throughout the year in different parts of the world including the southern Pacific, the northern Pacific, the Gulf of Mexico, the West Indies, Central America, the Caribbean, Hawaii, south Pacific and the Shark Bay.

The reproductive cycle of these bottlenose dolphins is unique among mammals. They have a gestation period of two months up to one year. The female bottlenose dolphin, as with human females, goes through a maturation period of one year. During this period they give birth to single offspring. The length of these dolphin’s lives is quite variable and is largely determined by the abundance of prey they can feed on in their natural environment.

This short life span leads scientists to believe that the reasons why these animals live so long is due to their slow rate of aging, their highly developed sense of smell, their ability to navigate the sea, their superior swim bladder, their broad range of movement, their placid personality and adaptability to various conditions and their resistance to attacks from predators. It is very difficult to study the marine creatures because of their great size, rarity in terms of sightings and their elusive nature. They are seldom seen in the wild and are far more likely to be kept in captivity where they can be studied in their laboratories. In most cases they can only be researched from samples taken from the coastal areas of the Pacific. In spite of this great effort to understand these animals the exact life expectancy is unknown.

Although most dolphins have been successfully studied in captivity, it is still very difficult to study these animals in their natural habitats. The main difficulty is that it is difficult to determine how old a dolphin is when it has just given birth or otherwise when it is no longer in the wild. There is a good chance that the mother might be carrying a low mature baby inside her, this makes it even more difficult to determine the age. Since the body of the marine mammal tends to deteriorate quickly, it is believed that the life expectancy of a calf could be less than 24 months. It is even possible that after a few years the calves start to become stronger and have a longer life span than their mothers.

How long do Dolphins live is extremely difficult to determine due to their slow growth rate and incomplete development. It is believed that there is a close relationship between the length of a dolphin’s life and the length of its lifespan. Life expectancy is affected by a number of factors such as the diet provided by the mother, the general health of the dolphins during their early life and their social and environmental conditions.

There are some marine mammals that grow rapidly, such as the humpback whale, the blue whale and the pilot whale. There are others that remain small and remain at a stable size through their entire lives. Bottlenose dolphins and the Australian pink dolphin for example, grow very slowly and remain small for most of their lives. It is believed that these dolphins have a very long lifespan.

As with all animals it is difficult to determine how long do dolphins live due to a variety of factors. Many people wonder how they are able to observe these creatures living in the wild and answer the question on how long do dolphins live? The best way to learn more about these animals is to consult a zoological facilities. These facilities will be able to provide you with accurate and current information on the life expectancy of different marine mammals. They may also be able to give you the chance to observe a dolphin in its natural habitat to better understand its behaviors.
