Cuttlefish in a hurry

Common cuttlefish, Sepia officinalis.

I took a similar photo of a cuttlefish at Bristol around 25 years ago.

Great photo! Are the cuttlefish in the aquarium? I don't remember seeing them.

@Daubentoniidae There's only one on show (I doubt if the tank is large enough for 2 adults). It is in the tank after the seahorses, which was completely refitted in the summer and will have needed time for the filtration system to mature, so I believe it has only been there for a few weeks.

Ok I went there early summer so probably missed it.
