Dusky Arion Slugs (Mating) - Arion subfuscus Arion slugs are hermaphrodites, and they can reproduce either by self- or cross-fertilization, depending upon conditions.  When two slugs mate with each other, they exchange sperm with their protruding genitalia.  If their sex organs become entangled, the slugs will simply bite them off in order to free themselves.  From then onward, the emasculated slugs will only able to reproduce as females.<br />

  1. Wild! Posted 2 years ago
    1. Yep! They were very cozy. I've always wanted to see slugs mating, so this really made my day. Posted 2 years ago
      1. Yeah I uhm can totally imagine this to be high on the list :) Posted 2 years ago
        1. It was so high! You know how fascinated I am by mating and mating rituals in nature. Sadly, while this was interesting to see, it was also really boring. I sat and watched them for a few minutes, yet the did not move at all. It looked more like they were asleep. Posted 2 years ago
          1. I couldn't find a video of arion slugs mating, but I did find this one of leopard slugs! Check it out!

            1. Pretty action-packed, was not expecting that lol. Also amazing how violins can turn something seemingly disgusting into the most beautiful thing. Posted 2 years ago
              1. Lol, so true. Electric guitar would have cheapened it, but violin made it so beautiful and romantic. Posted 2 years ago
          2. Just wait until you see my slug video. It's like watching paint dry!

            1. That's about how exciting watching them mate was. Although, I think it would have been more interesting to see them at the beginning of their sex session, to see how it gets started and how that "penis crystal ball" thing gets formed between them.

Arion fuscus, also known as the "Dusky Arion", is a species of small air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.

Arion subfuscus (Draparnaud, 1805) is considered by some authors to be a partial synonym for Arion fuscus. Arion subfuscus (Draparnaud, 1805) and A. fuscus (Müller, 1774) have very similar morphology and have overlapping distributional ranges in northwestern Europe. Arion fuscus is widespread throughout Central,.. more
