The species is [[Endemism|endemic]] to [[Sicily]].<ref name="Rhodin105"/> ==Etymology== The [[Specific name (zoology)|specific name]], ''trinacris'', is from the Greek word ''[[Triskelion|Trinacria]]'', meaning "three-pointed", the earliest known name for the island of Sicily.<ref name=RDB/> ==Subspecies== There are no subspecies of ''E. trinacris'' that are recognized as being valid.<ref name=RDB/> ==Description== ''E. trinacris'' is a small turtle. Maximum straight [[carapace]] length is {{convert|14.5|cm|in|abbr=on}}. The features of the turtle can vary depending on the location of the turtle, for example '''“Moreover, coloration of Lago Preola turtles is rather uniform, whereas turtles from Torre Salsa exhibit considerable coloration polymorphism.” (Fritz et al., 2006).''' The reason for this is because of a disruption in the gene flow caused by anthropogenic activities like industrialization. Since there are obstacles in the way like roads and buildings migrating to different groups is more difficult for the turtles. ''E. trinacris'' differs from ''E. orbicularis'' by its distinct mitochondrial DNA.<ref name=RDB>{{EMBL species|genus=Emys|species=trinacris}}. www.reptile-database.org.</ref> ==Habitat== The preferred [[habitat]] of ''E. trinacris'' is freshwater in ponds, lakes, rivers, and swamps.<ref name=RDB/> ==References== {{Reflist}} ;Bibliography *{{cite web |url=http://www.iucn-tftsg.org/wp-content/uploads/file/Accounts/crm_5_000_checklist_v3_2010.pdf |title=Turtles of the World 2010 Update: Annotated Checklist of Taxonomy, Synonymy, Distribution and Conservation Status |date=2010-12-14 |accessdate=2010-12-15 |last1=Rhodin |first1=Anders G.J. |last2=van Dijk |first2=Peter Paul |last3=Iverson |first3=John B. |last4=Shaffer |first4=H.
