Dumbo Octopus Flaps Ears
The dumbo octopus (Grimpoteuthis) lives at 7000m depths, 'flying' by flapping ear-like fins resembling Dumbo's. It lacks an ink sac and eats worms directly. Largest eyes of any animal aid abyssal vision.
💡 Fun detail:
It hovers upside down, pulsing fins for jet-free propulsion in crushing pressures.
