Virtually all fish have two sets of jaws - oral jaws and pharyngeal jaws, also known as the pharyngeal mill. The pharyngeal mill is normally used for crushing and grinding hard foods, such as crustaceans, but morays have evolved the ability to use them to grab prey held in the oral jaws and pull it into the oesaphagus. There's a good interview here: http://www.practicalfishkeeping.co.uk/pfk/pages/it em.php?news=1367
I don't think these are the first GM fish to go on sale. The Taikong Corporation, a Taiwanese company, marketed Gong's TK1 GM Zebra fish earlier in the year according to Practical Fishkeeping magazine. News story These fish are still (as far as I know) awaiting licensing in Singapore (one of the world's biggest producers of tropical fish) and one company has been prosecuted for importing them.
Illegal GM fish siezed
