Abstract

We hereby provide the first documented occurrence of the yellow tang Zebrasoma flavescens and the clown triggerfish Balistoides conspicillum in the Mediterranean Sea. These tropical fishes were photographed in October 2008 off Sitges (Costa Daurada, Spain: 41°13'27.09" N; 1°47'22.35" E) and in July 2012 in front of Palamós (Costa Brava, Spain: 41°50'56.19" N; 3°8'26.29" E), respectively.
