“Spookfishes are beautiful deep-sea fishes characterised by the presence of ‘tubular' eyes that see through its transparent head.” Aboard the research vessel the Seward Johnson, Mr Flynn went fishing in depths up to 1500m and made some fascinating findings, including a live specimen of the pint-sized but fierce-looking anglerfish, a barrel-eye fish, with its tubular upward-looking eye, several species of dragonfishes and loosejaws. Mr Flynn is using the data collected on this voyage as part of his study of mesopelagic fishes, which inhabit ocean depths between 100 and 1000m.
