@allofsaurus: Bigfin Squid The bigfin squid (Magnapinna) is an elusive deep-sea creature known for its eerie, alien-like appearance, bizarre "elbow" posture, and extreme habitat depth.Appearance and AnatomyThe "Elbow" Posture: They hold their arms and tentacles perpendicular to their body at a sharp 90-degree angle, creating strange jointed "elbows".Extreme Appendages: Their elastic arms and thin tentacles can stretch up to 15 to 20 times their mantle (head) length.Enormous Fins: They feature giant, rippling, translucent fins that make up a massive portion of their body length, resembling large larvae.Adhesive Filaments: Each tentacle ends in a long, thread-like filament covered in microscopic, sticky suckers used to passively snag prey.Habitat and DepthDeepest-Dwelling Squid: They live in the world's deepest oceans across the Atlantic, Pacific, and Indian oceans.Record Depths: They have been documented at depths exceeding 6,000 meters (20,380 feet) in trenches like the Philippine and Tonga trenches, making them the deepest known squid species.Behavior and MysterySeafloor "Walking": They are often spotted hovering near the bottom of the ocean, using their long filaments to trail along or "walk" across the seabed.Elusive Encounters: Fewer than 100 individual sightings or collections of Magnapinna have ever been recorded worldwide.No Adult Specimens Collected: Scientists have never successfully captured or collected a healthy adult specimen; our knowledge is based entirely on video footage and damaged juveniles.
