i liked the idea of the space mermaid I did so I decided to expand upon it.
Tractus homopiscus or commonly called space mermaids (gender neutral) are a highly elusive race found throughout space. Semi nomadic, they live communally within asteroid belts. Their queen, sometimes king, living within the largest asteroid.
Much like their earthly cousins they are enchantresses. They can manipulate their victims and machinery through “song”. Yet it is not the flesh of humans they are after, but their supplies and most importantly their oxygen. Though highly specialized to live in the emptiness of space they still rely on oxygen to breath. They need and use far less than humans, but are constantly on the look out to replenish their supply.
They can be incredibly dangerous. A large enough swarm is capable of taking down small embargo ships and entire crews. It is not uncommon for small ships to give oxygen tank offerings in hopes of appeasing them.
For larger, well-protected fleets they are nothing more than pests. With a specialized tube they can penetrate the strong ship walls and suck out oxygen.
Despite their human faces, it isn’t entirely known weather or not the face is their own, a projection or a mask. Some speculate that they have no form, and are gaseous entities encased.
This speculation comes from the sightings of “nebulous maids.” Thought to be the hallucinations of weary space traveller, these stardust phantoms have never been recorded so the consensus of their validity is non conclusive
