Shmengian Jellyfish

The Shmengian jellyfish is a large floating species of jellyfish from planet Shmengy.

Biology
They are large translucent cnidarian creatures that have a reproduction method similar to the Xenomorphs, only ending with the baby being shot out of the host's posterior true a lightning bolt, rather than bursting out of their chest.

Trivia

 * Their official name has never been mentioned, but it can be assumed that "Shmengian" is part of it, given the name of their planet, Shmengy.
