We aren't the tropical equator down here, but the slugs I see are much smaller than the big honkers I grew up around in western Washington state.

I've been seeing a few of a pest called land planaria that apparently eat earthworms. I've seen them stuck to the undersides of bags of mulch. Best to bundle the whole thing up and throw it in the trash. If you squash it it comes back from all of the segments.
