Millerigobius macrocephalus was previously considered endemic to the Mediterranean Sea, but it has recently been reported from the Black Sea around the Crimean peninsula. Millerigobius macrocephalus appears to be widely distributed in northern parts of the Mediterranean, with new localities reported in recent years. There is no specific population information for M. macrocephalus, but the population trend is assumed stable. There are no known widespread threats. Therefore, M. macrocephalus is assessed as Least Concern.

Geographic Range [top]

Range Description:Millerigobius macrocephalus is known only from the Mediterranean and Black Sea. In the Mediterranean, M. macrocephalus is found in northern areas, from east of the Alboran Sea eastwards along the northern coast to the Levant, with a single record from Israel. Records are from the Mar Minor and Ibiza (Spain; Ramos Espla and Perez-Ruzafa 1987), the Lavezzi Islands (Bouchereau and Tomasini 1989), Tremiti isles (Italy, Dufour et al. 2007), off Malta and Crete (Kovačić et al. 2013) and the Aegean Sea (Bogorodsky et al. 2010). It was recently identified from a nearly land-locked brackish water lake in Greece (Vanhove et al. 2011). Previously considered to be restricted to the Mediterranean, M. macrocephalus has recently been recorded from the Crimean peninsula in the northern Black Sea (Boltačëv et al. 2010), however the origin of the species here requires confirmation. Millerigobius macrocephalus has been collected to 10 m depth (Patzner 1999).
Countries occurrence:
Bosnia and Herzegovina; Croatia; France (Corsica); Greece (East Aegean Is., Greece (mainland), Kriti); Israel; Italy (Italy (mainland), Sardegna); Lebanon; Malta; Montenegro; Spain (Baleares, Spain (mainland)); Turkey (Turkey-in-Asia); Ukraine (Krym)

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Millerigobius macrocephalus occurs in inshore sandy shallows and lagoons, among and under stones (Miller 1986). It has recently recorded from a nearly land-locked brackish water lake (Vanhove et al. 2011).
