The Sluggish Secret of Slime
See a slug? Don’t rush off for that bottle of salt or bowl of beer (two favorite methods of execution for this shell-less mollusk.) Instead, check out this KQED Deep Look video.
According to Deep Look, slime is a slug’s greatest defense. The article accompanying the video states, “Banana slug slime contains nasty chemicals that numb the tongue of any animal that attempts to nibble it, discouraging predators like raccoons, who have to go to the trouble of removing the slime if they want to eat the slug. But this is just one of many ways slugs depend on slime, and they use it for everything from locomotion to nutrition.”
