This could be Cthulhu - a fictional cosmic entity created by writer H. P. Lovecraft and first introduced in the short story "The Call of Cthulhu".

What Cthulhu looks like? From H.P. Lovecraft himself:
If I say that my somewhat extravagant imagination yielded simultaneous pictures of an octopus, a dragon, and a human caricature, I shall not be unfaithful to the spirit of the thing. A pulpy, tentacled head surmounted a grotesque and scaly body with rudimentary wings; but it was the general outline of the whole which made it most shockingly frightful.
In 2013, the University of British Columbia (UBC) discovered two new octopus-like mircoorganisms which they named them after H.P. Lovecraft’s immortal creation.
The microorganisms, now officially named Cthulhu macrofasciculumque and Cthylla microfasciculumque, were discovered to have an octopus-like movement when observed under a microscope.
The appearance and unique movement of the two microorganisms reminded UBC researcher Erick James — familiar with Lovecraftian lore — of Cthulhu and his daughter, so he graced them with the two monikers. See more at Geek.com.
