Very exciting new arrivals - not yet labelled but I believe these two young sharks to be Scalloped Hammerheads Sphryna lewini. They're in the main tank with the Green Sea Turtles and Blacktip Reef Sharks.
I'm pretty sure they'd be the only ones in Europe (and the only Sphryna other than Bonnetheads as far as I'm aware).
Once Crabzilla moves on these are the big 2010 attraction but they don't seem to have done the press release yet so I can't confirm the species - I'll be emailing the centre to confirm. They're advertised here as 'the first hammerheads in Europe': http://www.groupfundays.co.uk/news_offers/default.asp?cat=6&type=3 (puts Bonnetheads in their place!).
