Life cycles/ Alien Fertilization

After seeing all the new footage, i cant help but think that the Cobra is very similar to a Sperm. The albino skin color and the fact its swimming in the black liquid support this too. The way it seems to target beings' heads/helmets leads me think its looking for an "egg". When a sperm reaches an egg, it releases different compounds that actually eat/melt a hole into the outer layer of the egg in order to get inside. This could be what is happening when the guys helmet melts all over his face. In another shot we see the "cobra" bursting out of the same crew member's face, probably because it realizes its not an egg. Another possibility is the Cobra "fertilizes" his head which mutates into an "egg" and a new creature (hybrid) bursts out of his face. It also resembles a Stamen from a plant. What we see unfurl is the Anther and it spread spores which infect (pollinate) the crew. Any thoughts?
