ok so that is a sick looking slug tbf.
But i have a question!

Stunning as it is, what do slugs in general do for the eco system? our culture suggests they are enemies of the garden. Do they do anything besides provide food for predators? they are in more than an abundance so is it ok for gardeners to cull them? thanks!

Have to say though it is a really stunning specemin you captured. Nice one as usual :D

Thank you~ It's a leopard slug, which can be quite big :3
Only very few gastropods could actually be considered harmful to gardens, though personally I dislike the idea of killing animals merely for being a nuisance. Anyway, yeah they do serve a role as being prey, but they are also vital to the decomposition process of dead insects and plants, and that in combination with where they slither around makes them spread nutrients across the dirt, so you could say they are recycling stuff from waste in a way. And this may seem surprising, but they are also pollinators! :D Very... very slow pollinators, but nonetheless, the pollen of some plants stick to them, making them help with the reproduction of those plants. But even beyond the a snail's lifespan, they still prove to be valuable thanks to their shells, especially in environments where naturally available calcium is lacking, and several species make use of the shell for living and egg laying purposes. :3
I also think gastropods are immensely interesting because of how strange evolution went with them. For example, while gastropods living on land tend to have their eyes at the end of their eyestocks, many ones living in water have them at the bottom of those stocks instead. I can't think of any other group of animal species where something as significant as eye placement can differ so drastically. Also interestingly, snails and slugs aren't as cleanly separated taxonomically as you might think, it's not that one half evolved into slugs and the other into snails, in actuality it's all mixed together, like, one species of snail may be closer related to a slug than a different snail in some cases, just to show the strangeness of it. They are weeeeeird, and I love them for it. :3 Also just really underappreciated~
When you pick up one if you ever decide to want to do so, don't pull at the shell while they're outside of it, they stick to the floor, so this would really hurt them, veeery gently tap at the shell to get them to go inside of it to then pick them up instead. And for slugs, best pick them up with wet hands, dryness can hurt them too, there's a reason why they're all slimy, they need to remain wet to survive, covering the ground below them with it because of that too. Of course, probably needless to say, but if you do hold one, make sure to wash your hands afterwards. ;)
One of my sona forms is a demon snail actually (as if my appreciation of them wasn't already obvious from this wall of text, lol), never drawn that form myself though, at least not yet. xp
