  • 1st MEDITERRANEAN RECORD
    Algerian coast, 1958.


    DISTRIBUTION
    Worldwide : Eastern Atlantic, from Gibraltar to Angola. Mediterranean : recorded first on Algerian coast (Dieuzeide and Roland, 1958). Successive records in the Gulf of Lions, France (Escoubet et al., 1981), Malta Channel (Insacco and Zava, 1999), Tunisian coast (Bradai, 2000), Strait of Sicily (Ragonese and Giusto, 2000) and Tyrrhenian Sea (Serena, 2001). More recently recorded in Livorno and in Catania (Italy), and in Mugla (Turkey).

    ESTABLISHMENT SUCCESS
    Very rare.

    speculated reasons for success :


    MODE OF INTRODUCTION
    Via Gibraltar.


    IMPORTANCE TO HUMANS
    None.
