A banana slug feeding on Amanita. Many terrestrial gastropod mollusks are known to feed on fungi. It is the case in several species of slugs from distinct families.Among them are the Philomycidae (e. g. Philomycus carolinianus and Phylomicus flexuolaris) and Ariolimacidae (Ariolimax californianus), which respectively feed on slime molds (myxomycetes) and mushrooms (basidiomycetes). [5]
There have been hybridizations of snail species; although these do not occur commonly in the wild, in captivity they can be coaxed into doing so. Parthenogenesis has been reported only in one species of slug, [21] but many species can self-fertilise. [22] C. obtusus is a prominent endemic snail species of the Eastern Alps.

[1] It is the second-largest species of terrestrial slug in the world, growing up to 25 centimeters (9.8 in) long. [1] As of 2021, it is the most commonly observed species in the genus Ariolimax on the citizen science website ...
Yellow slugs, like the majority of other land slugs, use two pairs of tentacles on their heads to sense their environment. The upper pair, called optical tentacles, is used to sense light. The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident ...
