REPRODUCTION OF ISOPODA Anthony Rich Lila Boudrie

Mating ■ Most cases females can only mate after moulting ■ Before molting females release pheromones to attract males ■ Male will attach and wait for female to molt, also guard her after mating ■ Usually able to identify gender by external extremities http: //sunny. moorparkcollege. edu/~econnolly/crustacean_files/image 010. png

Mating cont. ■ Males have a pair of penisis – Fused together in some species ■ Sperm transferred as a fluid or inside packets directly into the female reproductive organs or into storage sack ■ Fertilization does not take place until the eggs are shed after a moult https: //www. google. com/url? sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0 ah.

Isopoda life cycle ■ The eggs hatch as mancae, a post larval stage that resembles closely to an adult. – Only missing the back legs ■ They will molt multiple times as maturing. – Molt in two stages. – Biphasic moulting https: //www. google. com/url? sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0 ah.

Types of reproduction ■ Little sexual dimorphism amongst the species ■ Some species are hermaphroditic ■ Others are protandrous hermaphroditic – Start as males change sex to female later in life ■ Sexual reproduction
