Explanation / Answer

Hermaphrodite - This means the single organism contains both male and female sexual organs.

Most of the worms are good example for Hermaphrodites. Earthworm is also a hermaphrodite and contains both male and female sexual organs which produce sperms and eggs respectively in each earthworm. The sexual organs are present in 9-15 segments in Earthworm.

These earthworms mostly undergo Cross-Fertilization. This tends to share their DNA, and thus have a chance to develop an offspring with the characters of both the parents. A great benefit for hermaphrodite organism is that in conditions of scarcity in finding a mate, it can fertilize its own eggs and reproduce.
