Biology
Allolobophora chlorotica, green earthworm
Size
Roughly 3-8 cm long and 0.3-0.7 wide
Reproduction
Like all Earthworms Chlorotica is a Hermaphrodite. It however still finds sexual reproduction beneficial and mates below the surface of the soil in tunnels.
When worms mate they each pass each other sperm, which is then stored internally in special little sacs called spermathecae.
The worms then produce a wad of mucus over the clitellum which moves over the anterior of the worm. As it moves the worm releases its eggs and the stored sperm into the mucus. Once the mucus band detaches from the worm it seals up and forms a hard cocoon. The eggs are fertilised within.
Depending on environmental conditions in the soil the juvenile worms will emerge a few weeks to months later.
