Dumbo Octopus

• GeneralIt swims by flapping two fins like an elephant's ears; it is the deepest-living octopus known.
• anatomíaIt lives at great depth and moves by flapping a pair of fins on its mantle that recall an elephant's ears, which is where its common name comes from.
• It swallows its prey whole, without tearing it up, which is exceptional among cephalopods.
• The females carry eggs at different stages of development at the same time: on the abyssal floor, where there are no seasons, they can breed at any time of year.
• It is a dumbo octopus: its two lateral fins, reminiscent of elephant ears, are its main means of propulsion, something exceptional among octopuses, which usually swim by jet.
• It is among the deepest-living cephalopods known: its genus has been recorded at more than 7,000 metres.
• It has no ink sac. At that depth the darkness is total and a cloud of ink would serve no purpose, so the organ has been lost.
• Its arms are joined by a broad web that it spreads like an umbrella, and it swallows its prey whole instead of tearing it apart.
• Almost everything known about the group comes from specimens taken in research trawls and from a few videos shot by underwater vehicles.
• The female carries eggs at different stages of development at the same time and lays them one by one on the seabed or on corals, without caring for them afterwards.
