The life cycle of a snail starts with the young hatching, then progresses to the adolescent snail feeding and resting until it reach the age of reproduction, at which time the snail mates and lays eggs. Eggs are deposited in a nest below the soil.
The first part of the life cycle of a snail takes place in the wintertime, when it hatches from an egg located an inch below the surface of the ground. The young snail eats its shell and other snail eggs. The snail continues to feed and grow through the rest of the winter and the spring. As it grows, the shell does too, coiling outward.
During the summer, the snail rests above ground by climbing onto roads, fences and vegetation. The purpose is to lose as little water as possible during the hottest, driest times of the year. The snail continues in this feeding and resting pattern until it matures after a few years.
The snail's reproductive organs mature in the spring, but it does not start mating until the autumn rains. Because snails contain both male and female reproductive organs, they are hermaphrodites. Each snail fertilizes another snail's eggs and lays a clutch of eggs itself. The snail digs a shallow hole in the soil using its foot and lays up to 400 eggs a year in the winter. After two weeks the eggs hatch.Learn More
A female millipede lays eggs inside a nest underground where they undergo an incomplete metamorphosis. Once the eggs hatch, the baby millipedes remain in the nest until they molt at least once. The millipedes gain new body segments each time they molt until reaching adulthood in 2 to 5 years.Full Answer >
Scorpions can live from 3 to 8 years in the wild. Scorpions grow by shedding their hard outer shells. The moulting process occurs five to seven times until they reach maturity. At that time, their final exoskeleton forms. The average size of an adult scorpion is 2.5 inches long.Full Answer >
Aphids have a short life cycle and can produce a large number of generations each year. It takes roughly eight days for an aphid to reach adulthood.Full Answer >
In ideal environmental conditions, a slug may live up to six years; however, most slugs live two years. Most slugs start off as eggs, hatch into immature adults and develop into adults in just under a year, though there are a few species of slugs that have live births.Full Answer >
