Dear Bob, wonderful photos. I'm contacting you 'cause our research group is looking for divers that have observations and eventually photos of invasive fish species. This is a collaboration project between scientist and divers called Seawatchers (Observadores del Mar in Spanish) which includes an action dedicated to 'fish invaders'. Our only aim is to track the advance of these invaders and your observations can be really important for us and for Mediterranean science. We look for records of the worst invasive fishes like the siganids you have already photographed But if you have a photo of an unidentified fish and you think it might be an invader, you can post it to us and we will identify the species. Let me know if you can be interested in collaborating with us the only we ask you is your observations I hope to hear from you soon Ernesto Azzurro Seawatcher scientific team editor1seawatcher@gmail.com
