Oh the strange yet beautiful world of biodiversity! Take a look at these unique underwater species. 🌊 These armored searobins (Triglidae) use modified fins to move across the seafloor and branched "whiskers" in front of their mouths to help them sense food. 🌊 This rare octopus is often called the blind octopod due to the lack of a lens and reduced retina in its eyes. 🌊 An Opisthoteuthis agassizii, observed during a dive of the NOAA 2019 Southeastern U.S. Deep-sea Exploration. The dots are clear windows in the skin. 🌊 A deep sea jellyfish, Atolla sp., collected with the ROV (Remotely Operated Vehicle), from a depth of at least 1,500 meters. The coloration is invisible in the perpetual darkness and at the same time masks any bioluminescence of prey in the medusa's gut. 🌊 A Frill shark swims in a tank on Jan. 21, 2007, in Numazu, Japan. It's body shape and the number of gill are similar to fossils of sharks that lived billions of years ago. 🌊 An adult bigfin squid, genus Magnapinna, are the deepest known squids and while sightings of them have been recorded globally, the total number of sightings is likely less than two dozen. 🌊 A gummy squirrel (“Psychropotes longicauda”) at 5100 m depth. This animal is ~60 cm long (including tail), with red feeding palps (or “lips”) visibly extended from its anterior end (right).
