How long do mollusks live?

The lifespan of mollusks varies greatly depending on the species. Some species, such as squid and cuttlefish, have a lifespan of only one to three years, while others, such as clams and mussels, can live for up to 100 years. The lifespan of a mollusk is influenced by factors such as predation, disease, and environmental conditions. Additionally, some mollusks, such as the Giant Pacific octopus, exhibit semelparity, meaning that they reproduce only once before they die.
