Figure 2 - Geographic distribution of the genus Onchidium and its three valid species. The colored dots correspond to the known records for each species. Colored areas correspond to hypothetical ranges proposed based on those known records. Naturally, details about the distribution of each species remain uncertain. For instance, Onchidium typhae may or may not be found on the western coasts of Thailand by the Andaman Sea.
