If you want to know exactly what creature I'm referring to, look at Feasibility of Carnivorous Flower-worm. Let's say I want people to be able to ritualistically implant these creatures to gain the benefits of increased energy (from their photosynthesis) and a monster alarm system (from their creature-sensing ability).
This requires a few abilities:
Ability to connect to nervous system/release chemical signals into the host for communication
Be able to share nutrients with the host
Be able to extend "roots" that it can regenerate from if it's cut off
Be able to sense and differentiate from organisms around it
How can this be made possible?
Please Note: I'm not asking you to explain how this creature can be implanted into a human being, but rather I'm asking you to explain how the four abilities above could work. In other words, I'm asking for adaptations that would allow it to function as an implant, not an explanation of how it could be implanted.
As for why: As an interesting feature I pictured a race of extremely nature-attuned people (Forestkin, they see themselves as an extension of the forest, one with nature) cutting themselves and then implanting an Anklebiter (AKA flower-worm) in their wounds. The Anklebiter would allow the Forestkin to gain energy from the sun and sense nearby living things, making hunting and evading monsters much easier. I picture these Anklebiters being implanted behind the ears, as these worms do look like flowers after implanting.
What, Exactly, Am I Asking?
- I'm asking for explanations for the abilities above. Magic is involved, but not much, so all I really need is a biological basis for each ability.
