The capture of larvae of Palaemon macrodactylus off Mallorca (Balearic Islands) has been recently reported as evidence of a potential presence of a population of this species in the Mediterranean Sea. Photos of this species, taken during dives in the Sacca di Goro (northern Adriatic) were published in the same year, but no specimen could be collected at that time. Herein we report the capture in 2013 of numerous individuals of...

The alien hippolytid shrimp Lysmatakempi Chace, 1997 (= Hippolysmatadentata Kemp, 1914) , never recorded after its original description fromthe Eastern Indian Ocean, is reported for the first time in the easternMediterranean Sea (Gulf of Antalya), with remarks on its taxonomy.

The state-of-art on alien species in the Mediterranean Sea is presented, making distinctions among the four subregions defined in the EU Marine Strategy Framework Directive: (i) the Western Mediterranean Sea (WMED); (ii) the Central Mediterranean Sea (CMED); (iii) the Adriatic Sea (ADRIA); and (iv) the Eastern Mediterranean Sea (EMED). The updated checklist (December 2010) of marine alien species within each subregion, along w...

The burrows of Squilla mantis are described from polyester resin casts taken at two Adriatic sites near Ancona. Typically, burrows had two openings, one of which was larger than the other, and were basically U‐shaped. An interesting association with the little‐known caridean shrimp Athanas amazone was observed. The sediments occupied by S. mantis were silty sands and sandy muds. Field observations of S. mantis and other specie...
