Octopuses live anywhere from 6 months (pygmy) to 3-5 years (Giant Pacific Octopus) to possibly a few years longer in colder waters. At the end of her life, the octopus mother lays eggs, which she guards and cares for in her den. She begins to waste away and eventually dies, usually soon after the eggs hatch. There are two types of octopus eggs - some octopuses produce very small eggs, and the hatchlings are tiny and exist as a type of plankton until they eventually grow larger and sink to the ocean bottom to begin their life as octopuses. The larger eggs produce larger hatchlings that look like tiny octopuses.
Octopuses are sometimes kept as pets and are the most successfully kept cephalopod. They need to be kept in a "species tank", a salt-water aquarium devoted to one octopus. Although most of these octopuses are "wild caught", there are people trying (with some success) to breed octopuses to sell as pets. The most popular species seems to be O. bimaculoides, a small California octopus that lives near the shore and is active during the day. Other types of octopuses found in peoples' homes are O. vulgaris, various pygmy species, and the "Bali octopus". Often the pet dealers do not know what species they're selling and may offer them as "brown octopuses", "tropical octopuses," or "transparent octopuses."
