Description
Nudibranchs are hermaphrodites. They contain both male and female reproductive systems. During copulation, they line up their genitals which are on the right side of their body. Each nudibranch receives sperm from the other. When the nudibranchs have finished mating, it takes quite an effort to pull the genitals apart.
