some unknown species that is the result of convergent evolution between the Scyphozoa
(jellyfish and octopus)
I don't even...
All I know is that it draws food in through the "neck-mouth" which has the ability to quadruple its diameter for consumption of larger prey and the the "tentacles" pick up chemical and electrical signatures in the water which allows this creature to locate and hunt prey.
I did this in Biology class when we were learning about convergent and divergent evolution...
