The '''fat Guam partula''' or '''humped tree snail''', scientific name '''''Partula gibba''''', is an endangered species of air-breathing land snail, a terrestrial gastropod mollusk in the family Partulidae.
==Distribution== This species occurs throughout the Mariana Archipelago, and has been reported in the greatest densities and population sizes on the isle of Sarigan.<ref name=":0">{{Cite journal|last=Berry|first=Lainie|date=January 2016|title=Partula gibba feeding on Mariana fruit bat ejecta of Pandanus sp. fruit on Sarigan, Northern Mariana Islands|url=https://micronesica.org/sites/default/files/berry2016finalproofv3.pdf|journal=Micronesica|volume=1|pages=1–4}}</ref>
== Ecology == On Sarigan, the species has been recorded most frequently in high-elevation native forests on the trunks of large ''Erythrina variegata'' specimens, often resting at the base of branches. On 19 May 2015 specimens were found consuming the Pandanus-fruit ejecta of the Mariana fruit bat on the leaves of a ''Pandanus tectorius'' tree. Mariana partulids have been noted to consume plant material, both living and decaying.<ref name=":0" /><ref>{{Cite journal|last=Perez|first=Kathryn E.|date=February 2010|title=Current Research on Land Snails and Land Snail Conservation: Leslie Hubricht Memorial Symposium on Terrestrial Gastropods|journal=American Malacological Bulletin|volume=28|issue=1–2|pages=13–14|doi=10.4003/006.028.0206|bibcode=2010AMalB..28...13P |s2cid=85018835|issn=0740-2783}}</ref>
