There is no definite lifespan for lobsters. In their habitat, they can live for more than 100 years easily. Due to their biological immortality (Not immortal, but they do not experience senescence), they can survive more than 1,000 years.
However, it does not mean that no lobsters have a less lifespan. Some lobsters live for 30-80 years, also. It actually depends on the region and the species of the lobsters.
This article will describe all details of the lifespan of lobsters.
| Lobster Species (Common) | Lifespan (Average) |
| American Lobsters | More than 100 years |
| European Lobsters | 30-80 years |
| Norway Lobsters | 10-20 years |
| Cape Lobsters | 50-100 years |
| Nephropsis Rosea | 100 years (approx) |
| Thymops | 5-20 years |
| Tasmanian Gaint Freshwater Lobsters | 100 years (approx) |
How Long Do Lobsters Live?
Researchers have yet to confirm any exact number regarding how long lobsters live. But, they found that depending upon the habitat and types, the longevity of lobsters living may vary.
For example, European lobsters have a short lifespan compared to American lobsters. Where a European lobster lives for 30-80 years, an American lobster lives for more than 100 years easily.
One of the oldest lobsters (George) was found in Newfoundland, Canada, at 140 years old. It can easily live more than 100 years in its natural habitat and environment.
In captivity, lobsters live shorter than they do in the wild. In a tank or aquarium, they can survive for 10-15 years maximum. It happens because of several factors, including the quality of water and proper nutrition.
But in their natural habitat, lobsters have no natural predators and can easily avoid hazardous environmental conditions. These conditions increase their chance of survival and result in a longer lifespan.
How Long Do Lobsters Live in Aquariums?
Some researchers estimate that lobsters living in an aquarium can live for 10-15 years maximum. When they are in their natural habitat, they can reach 100 years easily.
The conditions in an aquarium are different from those in the sea, so a lobster’s lifespan will be shorter when kept in an aquarium. This is because lobsters only eat supplements instead of natural food sources.
Why Do Lobsters Live So Long?
Lobsters have a long life due to a never-ending supply of an enzyme called “Telomerase,” which works to keep regenerating telomeres.
Telomeres are structures at the end of each chromosome that protect our DNA as it replicates. Every time a cell divides, its telomeres get shorter. Eventually, they become too short to do their job properly, and the cell dies—this is what we know as aging.
Lobsters’ cells divide more slowly than ours do (about once every 14 days), but even so, their telomeres would eventually shorten enough to kill them if something didn’t prevent it from happening. And that something is an enzyme called Telomerase.
So, do lobsters die of old age? No, they don’t. Every time a lobster’s cells divide, this Tolemerase enzyme goes into action, rebuilding those critical bits of DNA so the chromosomes can function normally again—thus ensuring an extended lifespan for these interesting sea creatures.
Since they also replace their cells less often, their DNA stays intact for a longer time—and that gives them an advantage when it comes to aging. It is much more difficult for their telomeres to get shortened or broken, and the lobsters’ cells don’t become damaged as easily. That is why they can live so long and remain healthy until the end.
Are Lobsters Immortal?
There is a myth that lobsters are immortal because they continue to grow throughout their lifetime. However, this is partially true. While lobsters do continue to grow, they are still subject to injuries and diseases. Also, lobsters can be killed and eaten by humans and other predators.
While lobsters have a longer lifespan than other animals, they are not immortal. The average lifespan of lobsters depends on various factors, such as their species.
Moreover, in the case of lobsters’ lifespan, they can be called biologically immortal because of their telomerase enzyme.
Which Lobsters Live More: Male or Female?
Another factor affecting the lifespan of lobsters is their sex. From research, male European lobsters have an average lifespan of 31 and females of 54 years. While in American lobsters, males have an average lifespan of 50 and females 90 years.
Why is there a difference? Male lobsters often roam or migrate to find their mating partner, which increases their chance of being captured by fisheries and other predators. On the other hand, female lobsters are more likely to be cautious about potential dangers, resulting in a longer lifespan.
There is often a size difference between male and female lobsters of the same species. Males are usually taller, making them more vulnerable to predators; however, some males have longer lifespans than females.
This discrepancy occurs because females expend large amounts of energy on reproduction and incubating eggs, ultimately shortening their lifespan.
What Can Affect a Lobster’s Lifespan?
Besides the sex and type of lobsters, some factors can affect their lifespan. One of them is a disease. Lobsters can suffer from several diseases, including shell rot and tail rot. These diseases weaken their immune system and can ultimately result in death.
Other factors include environmental conditions, such as temperature and pollution. These can also affect their immune system and potentially shorten their lifespan. Water quality and proper nutrition in captivity can also affect a lobster’s lifespan.
Eaten by predators and caught by fishery can shorten a lobster’s lifespan. However, lobsters have the ability to regenerate lost limbs or claws, which increases their chance of survival in these situations.
Human actions, such as overfishing and the destruction of habitats, can also have a negative impact on the lifespan and population of lobsters. By practicing sustainable fishing methods and protecting their natural habitats, we can increase the chance of survival for lobsters and prolong their lifespan.
FAQs
Can lobsters live 200 years?
Yes, lobsters can live 200 years easily in their natural habitat. However, their longevity also depends on factors like their species and sex. Male lobsters have a shorter lifespan compared to female lobsters.
What is the standard water temperature for a lobster living?
Normally, water temperatures lower than 20° Celsius are ideal for lobsters, as research says. The “stress threshold” for lobsters is reached when water temperatures are over 20° Celsius.
They will have trouble reproducing since prolonged exposure to warm water will harm their respiratory and immunological systems and cause shell disease.
Furthermore, the variety of lobsters also makes a difference. For instance, American lobsters typically live in waters with temperatures ranging from 0 to 25° Celsius. In contrast, tropical lobsters typically thrive in water that is around 25 to 31° Celsius.
How can you tell the age of a lobster?
There are a few ways to tell the age of a lobster. One is to look at the lobster’s shell. As lobsters grow, they molt or shed their shells. A lobster’s shell will have growth rings that indicate its age, much like the rings on a tree trunk.
Another way to tell a lobster’s age is to look at its claws. Lobsters have two types of claws: larger crushing claws and smaller pincer claws. The size of the pincer claws is usually proportional to the lobster’s age.
Finally, another way to estimate a lobster’s age is to look at its tail length. In general, older lobsters will have longer tails than younger lobsters. Considering all of these factors makes it possible to get a good estimate of a lobster’s age.
How long do lobsters survive without food?
Lobsters can go without food for almost an entire year and still survive, though this varies depending on the species. Some types of lobsters can also lower their metabolic rate to further help them preserve energy. Even so, eating regularly is essential for both their health and longevity while in captivity—twice a day is ideal.
How long do lobsters live out of water?
Lobsters can survive out of water for a few hours if kept moist and cool. However, prolonged exposure to air can result in dehydration and, eventually, death.
In some cases, if the water temperature is too warm, lobsters may also leave their natural habitat to seek cooler waters, potentially leading to their death. It is necessary to release lobsters back into the water as soon as possible if fishermen catch them.
Can lobsters live in freshwater?
No, lobsters are marine animals that thrive in saltwater. They have specialized organs called branchiostegal lungs that allow them to extract oxygen from saltwater. In freshwater, they would not be able to breathe properly and ultimately die.
Can lobsters feel pain?
There is still debate among scientists about whether or not lobsters can feel pain. Some studies have shown that they have similar responses to painful stimuli as other animals. In contrast, others argue that their nervous system is not complex enough for them to experience pain.
Ultimately, the most humane way to kill a lobster for consumption would be to quickly and efficiently stun or kill it before cooking.
Conclusion
Lobsters can live for a long time, with some species potentially reaching over 100 years old. Their life span can be affected by things like their sex, diseases, the environment, and what people do. Practicing sustainable fishing methods and protecting their habitats to prolong their lifespans is essential.
