the deep sea is fascinating

Bigfin squids are a group of rarely seen cephalopods with a distinctive morphology. They are placed in the genus Magnapinna and family Magnapinnidae.[2] Although the family was described only from larval, paralarval, and juvenile specimens, numerous video observations of much larger squid with similar morphology are assumed to be adult specimens of the same family.[3]
Estimates based on video evidence put the total length of the largest specimens at 8 m (25 ft) or more, with some estimates up to 12 m (40 ft)

Magnapinna is thought to be the deepest-occurring squid genus, with sightings as deep as 6,212 metres (20,381 ft) below the surface, making it the only squid known to inhabit the hadal zone.

For the longest time after I first saw this video I thought the squid was moving at super fast speeds, I didn't register that it was the camera moving and it made me so terrified
