Looks pretty amazing Carol Nistri! I'm no marine life expert, but this looks like a new species of squid, yet with flexible wraparound skin with suction cups instead of tentacles to capture and suffocate (small sea fish/mammal) prey. Seems very different from deep sea fish, sting rays or jelly fish.
A man of Trachis' warning:
"When the Barbarians discharge their arrows they obscure the light of the sun by the multitude of the arrows"
Dienekes of Sparta's reply:
"Good news, for if the Medes obscure the light of the sun, the battle against them will be in the shade"
~Dienekes, Battle of Thermopylae 480 BCE [Herodotus 7.226]
