The c rayfish starts its life as an egg. The female and male crayfish mate and the female lays hundreds of eggs. The eggs attach to the swimmerets/tail of the female and when the eggs hatch, they are fully formed, albeit tiny. They stay with the mother for 1-2 weeks. In 2 weeks, the crayfish is about 1 centimeter long. This is when the crayfish will venture out on their own. They reach full adult size at 3-4 months. The average lifespan out in the wild is 3-8 years. --third grade teacher
