Observations of previously unrecorded non-native species in the Gulf of Cadiz (Spain), situated between the Atlantic Ocean and the Mediterranean Sea, have accelerated since 1980, and increased rapidly in the past 5 years. Four new records of decapod crustaceans have been detected in this region: the African snapping shrimp Alpheus sp., the West African cleaner shrimp Lysmata uncicornis, the Indo-West Pacific giant tiger prawn, Penaeus monodon, and the Atlantic blue crab Callinectes sapidus. The introduction and establishment of these species into the coastal waters of this region, the southernmost Atlantic coast of Spain may have been influenced by recent anthropogenic alteration of habitat, particularly estuaries and salt marshes, and by climate change facilitating the spread of warm water biota.

自1980年以来，对位于大西洋和地中海之间的加的斯湾（西班牙）先前未记录的非本地物种的观察速度加快，并且在过去5年中迅速增加。在该地区发现了十足纲甲壳类动物的四个新记录：非洲鲷鱼虾Alpheus sp。，西非清洁虾对虾Lysmata uncicornis，印度洋-西太平洋巨虎虾，斑节对虾和大西洋蓝蟹Callinectes sapidus。这些物种在西班牙最南端的大西洋沿岸地区的沿海水域中的传入和建立，可能受到最近人类活动的栖息地变化（尤其是河口和盐沼）的影响，以及气候变化促进了温水生物群传播的影响。
