Deep sea creature team, from the Universite Pierre et Marie Curie, has developed a capture device known as the PERISCOP, which maintains water pressure as it surfaces, thus keeping the samples in a pressurized environment during the ascent. This permits close study on the surface without any pressure disturbances affecting the sample. The BBC's Blue Planet has featured deep sea creatures, highlighting their peculiar attributes. Deep sea creature The term deep sea creature refers to organisms that live below the photic zone of the ocean.
