Semi-slugs, also spelled semislugs, are land gastropods whose shells are too small for them to retract into, but the shell is not quite vestigial. The shell of some semi-slugs may not be easily visible on casual inspection, because the shell may be covered over with the mantle.
This is a type of gastropod that is intermediate between a slug (without an external shell) and a land snail (with a large enough shell to retract completely into).
There exist a number of gastropod families that have semi-slugs species. There exist about 1000 species of semi-slugs in comparison to about only 500 species of slugs.
Semi-slugs from the Neotropics:
Jaz sem z'ivc'na egocentric'na svinja
te zajebem na vsakem koraku
jaz sem z'ivc'na egocentric'na svinja
po svetlem in po mraku
in ni me sram priznat
da sem pretepel bogo starko
in ji ukradel 200 mark
Jaz sem z'ivc'na egocentric'na svinja
sem zloben da je grdo videt
c'e pos'teno ocenim zadevo
bi me moral kdo zapret
imam rad samo svojo mamo
in se pos'c'ijem na ostali svet
