This week in fish: Warty Anglerfish

It was a 'four day week' this week so we are down an image or two from normal.  Despite that, there are still some great additions.  The Warty Anglerfish is an amazing looking fish and the Red Indian Fish has always been one of my favourites.  This week's blog post, 'Grey Carpetshark senses' is certainly worth a look.  Thank you as always to our contributors.
