Type locality of Lepadichthys erythraeus, Governorate, Hurghada (Al-Ghardaqa). Known from the Gulf of Aqaba and Gulf of Suez. In 2008 a specimen was collected from the base of a coral block (about 1.5 m in diameter) on a reef flat with mixed sand and flat rock with patches of dead corals; it was collected from within this live coral head in a depth of about 1 m in the sheltered Mangrove Bay (El Quseir). Later, in 2011, another specimen was collected from Sharm el Moya area (Sharm el Sheikh) from a fringing reef at a depth of 1-3 m and three specimens at the entrance of Sharm el Moya Bay from an isolated coral block. All collected specimens were in close association with sea urchins of the genus Diadema, utilizing the long spines for shelter (Ref. 103877).
