What distinctive reproductive characteristic do slugs possess?

Slugs exhibit a distinctive reproductive characteristic where they possess both male and female reproductive organs. This hermaphroditic trait allows them to mate with any other slug they encounter, increasing their reproductive opportunities. During mating, two slugs can exchange sperm, and because they both have capable reproductive organs, they can each produce fertilized eggs. This adaptation is significant for their survival and colonization, especially in environments where finding a mate may be challenging.

While some creatures may reproduce asexually or give live birth, slugs primarily rely on their hermaphroditic nature to enhance their reproductive success. Additionally, the practice of laying eggs is common, but slugs typically deposit their eggs in moist environments, which does not necessarily limit them to laying eggs in water. Thus, the characteristic of having both male and female reproductive organs is a defining feature of slugs.
