Neomorph

"An Endoparasitoid species of organism encountered by the crew of the USCSS Covenant.  While it shares some characteristics with the organism Xenomorph XX121, most notably it's process of gestating inside a living host organism and it's elongated skull, it it otherwise quite different".  

Yes, I saw Alien: Covenant, and while I won't throw out any spoilers, I WILL say I thoroughly enjoyed it!  A delightfully disturbing movie.

The "Alien" franchise is owned by Scott Ridley.
