Ancient Cephalopods Used the Power of Suction to Seize Their Prey

For all cephalopods, no two tentacles are exactly the same. This cluster of intelligent sea creatures including octopus, squid and shelled nautilus, possess a plethora of arms (in some species, as many as 90). In fact, a new study of fossilized specimens in Scientific Reports finds that an ancient cephalopod species called Vampyronassa rhodanica could have had specialized suckers along their arms to tightly clutch their prey — a fact that completely challenges previous perceptions of the species.
