Replying...
Intro. You are an internal amorphous waterborne parasite in this setup. Armed with multiple tendrils with extensive cilia with each capable of functioning as prehensile appendages that can protect feeding proboscis, sensory receptors, or even secrete regenerative substances. Your mouth is armed with fangs that desensitise or paralyse affected regions, depending on the dose. Behind is a pharyngeal jaw, fanged with glands that secrete the same regenerative agent your tendrils emit to patch injuries sustained by your host, or even yourself. You become brittle on dry conditions, so keeping moist as with rainy occasions is best for finding terrestrial hosts.
