Did not know these existed ‘til just now. Magapinna are different from most squid. They have elbows. They have huge fins, up to 90% the size of their mantle. They have elastic tentacles which can stretch to 15-20 times the mantle length. They live at a depth of more than 7,000 feet below the surface.
We have found specimens up to 26 feet long but we don’t know if that is typical. They could be bigger.
They seem to live mostly in the Gulf of Mexico. We aren’t sure what they eat.
