This week we feature the incredible Glasshead Barreleye along with underwater images of the famous Smalltooth Cookiecutter Shark. We show divers descending through clear water at the Kermadec Islands and watch a Pacific Leaping Blenny go through its paces. Thank you very much to everyone who contributed.
This has to be one of the strangest fishes you will ever see! Adrian Flynn sent images of the this amazing fish collected from a depth of about 1000 m. The Glasshead Barreleye has not only true eyes that look upwards but also 'secondary eyes' that collect light from the sides and below. Thank you Adrian for the images and supplementary information.
