I had to terminate this invasive juvenile black slug. It's in an area that's part of an ongoing rewilding community, environmental project. We remove them from areas where we're trying to protect native slugs & native habitat. Taildropper slugs are a native slug species at threat here on Vancouver Island & it's important to do our best to protect their habitats.
Even though these are called black slugs, they have a wide colour range & most found here exhibit this brown colour, when young.
Black slugs can lay up to 150 eggs at a time. They reproduce very quickly, which causes their population to grow beyond manageable in a short time period, if left to breed.
By comparison, native slugs lay only 20-30 eggs & are slower to reproduce.
