A list of sea slugs (i.e. Heterobranchia but mostly 'Opistobranchia') that are know to occur in Colombian coasts (both Caribbean and Pacific).

Most species records come from literature and some from observations on iNat or other platforms. This is not intended as an extensive or rigorous list, but as a guide to ID future observations.
