Hi Jen.  You were right to question the identification.  The fish on the Austmus Deep Oceans Discoveries site are not Blue Grenadiers, but rather a species of Blobfish (family Psychrolutidae).  The most famous of which is the much-loved Mr Blobby.

Question Dr Mark, any help with an ID of these fish?? The original blog post said Grenadier Fish.... Would like an expert opinion though.
