The extinction of the scorpion is inferred from the lack of live or recently dead specimens.[1][2] In December 2015, more scorpions remains were found in the nearby Levana Cave.[3] References1. ^1 2 Levy, 2007 "The first troglobite scorpion from Israel and a new chactoid family (Arachnida: Scorpiones)" [https://dx.doi.org/10.1080/09397140.2007.10638209] 2. ^1 Victor Fet, Michael E.
