TETRAODONTID COLONIZERS IN THE AEGEAN SEA; SECOND RECORD OF THE SPINY BLAASOP, TYLERIUS SPINOSISSIMUS (ACTINOPTERYGII: TETRAODONTIFORMES: TETRAODONTIDAE)

A second record of the small Indo-Pacific fish Tylerius spinosissimus (Tetraodontidae) (known as spiny blaasop) was documented at the beginning of 2009 in the waters of Rhodes Island (south-eastern Aegean Sea, Greece). The finding shows the putative establishment of a population of this alien fish in the Mediterranean with a centre the Dodecanese plateau.
