How long do cuttlefish live?
Two years
Cuttlefish have a short life span, but they grow quickly. They may only live one or two years, but some species can grow up to about 23 lbs (10.5 kg). Since they have such fast growth rates, cuttlefish are careful not to expend too much energy and usually spend about 95 percent of their time resting.
Cuttlefish have relatively short lifespans compared to some other marine creatures. On average, most cuttlefish species live for about one to two years. However, there can be variation in the lifespan of cuttlefish based on factors such as species, environmental conditions, and predation. Some larger species, like the Australian giant cuttlefish, tend to have longer lifespans compared to smaller species.
The shorter lifespan of cuttlefish is primarily due to their semelparous reproduction strategy, meaning they reproduce only once in their lifetime. After mating and laying their eggs, most adult cuttlefish die shortly thereafter. This is in contrast to iteroparous species, which can reproduce multiple times throughout their lives. Cuttlefish invest a significant amount of energy into reproduction and raising their young, and their relatively short lifespan is a trade-off for their reproductive strategy.
Despite their short lives, cuttlefish are known for their intelligence, remarkable color-changing abilities, and complex behaviors, making them captivating subjects for marine biology research and a fascinating part of the underwater world.
