![]() These snails range in size from approximately 5-12 mm and are both arboreal and ground dwelling and lay large gelatinous egg masses. ![]() ![]() Hawaiʻi has 42 endemic species in the globally distributed family Succineidae. Interestingly, the shells of the Euconulids are translucent, so the colors you see on the shell are actually the snails organs and body showing through. The Hawaiian Islands have 60 described species, but the family is distributed globally. These flat round snails with a shell diameter of 3-10 mm resemble cinnamon buns, and can be found on the ground and in the vegetation. The following pages describe SEPP priority species in the family Achatinellidae: While the large tree snails give live birth, other smaller species such as those in the genus Auriculella lay eggs. The family is diverse with both arboreal and ground dwelling species. This is perhaps the most well-known family because Achatinelinae, a sub-family within the Achatinellidae, contain all three genera of large arboreal tree-snails of which 44 species are listed on the U.S. In general all species are cone-shaped and range in size from some of Hawaii’s smallest land snails at 2mm, to some of our largest at over 22 mm. The following pages describe SEPP priority species in the family Amastridae:Īll 209 described species in the family Achatinellidae are endemic to the Hawaiian Islands, however other species in this family occur throughout Oceania. today less than 20 species remain, and all are on the verge of extinction. Unfortunately this entire family has experienced catastrophic levels of extinction. In general, Amastrids are considered to be ground dwelling or semi arboreal, and they are detritivores, feeding on dead and decaying leaves of native plants. Even more special is the fact that the entire family is endemic to the Hawaiian Islands. The family Amastridae is the most speciose family in the islands with 325 described species. Below is a brief introduction to the 10 land snail families present in the Hawaiian Islands, listed from most speciose to least.
