The correct phrase should be "of their bodies" because "slugs and snails" are plural.
So the possessive pronoun should also be plural ("their" instead of "its").
The corrected sentence would be:
"Most slugs and snails breathe using a lung which opens through a small hole in the side of their bodies."
