What is the life cycle of mollusk?

Answer 1

hatch-mate-die

Answer 2

The life cycle of mollusks is different for each creature and their species.

Most squid follows a similar pattern. Female squid spawn, leaving fertilized eggs in the water. Depending upon environmental conditions, the eggs hatch within about two weeks. Larvae, called rhynchoteuthion, emerge. During development, the larvae forms two tentacles and the eight arms grow in length. As an adult, the male squid will fertilize the females eggs and the spawning process will begin again.

The life cycle of the octopus also varies among species, but generally follows a similar pattern. The male octopus places his tentacle inside the female's cavity and inserts a sperm packet. He then dies. The female octopus will lay 50 to 100 eggs and carries them around in the area between her tentacles. While guarding her eggs, she doesn't eat and will die shortly after they hatch. A tiny octopus emerges from each egg and grows to an adult when it too will mate and begin the life cycle again.

The snail life cycle varies between species, with some requiring sexual reproduction and others reproducing through self-fertilization. In those where sexual reproduction is necessary, two adult snails--both of whom usually have both male and female reproductive organs--will mate and both will produce fertilized eggs. The eggs are deposited into the soil and will remain there for about four weeks before hatching. The larvae have a shell at birth, but must quickly consume calcium to make the shell grow hard. The snail will continue to mature and in most species doesn't reach sexual maturity for a couple of years.
