Deep Ocean Life Forms

Ever wondered what lives on the bottom of the ocean – or in the bottom waters? A catalogue of deep sea life forms can be seen at www.marlin.ac.uk/deep-sea-species-image-catalogue/ but there are of course lots more, estimated at around 230,000 marine animals that are currently known – but there is a total of well over 500,000 species yet to discover (see www.physorg.com/print219062315.html )
