I was thinking about bifurcator anatomy...
Soooo... Bifurcators are sort of simple looking critters with a variable amount of arms radiating out of a central chassis. The chassis is rigid and probably the only bone they have, and it contains their important internal organs. The arms, meanwhile, are entirely muscle. They can stiffen for gross motor functions like walking, or relax and split apart for fine motor functions like manipulating objects.
What's new is that they've now got little sensory pores all over their chassis which serve a variety of functions. I imagine that, like their arms, a bifurcator can have a variable amount of them. Pores can be eyes, ears, olfactory organs, airways, mouths or pit organs.
Not too dissimilar to earthling starfish, they have an eversible stomach they can throw up. I'm thinking their insides are hot pink. For funsies. (What makes it that color? I'm still working on that.) Unlike starfish, however, they don't have a through gut. They just absorb whatever nutrients they can get their Goofy Pink Feeding Appendages on and then spit out the excess later. Generally, a bifurcator will only have one of these, but it's not unheard of to have multiple. It's usually seen as rude to have your feeding appendage out for no reason, since those digestive enzymes can seriously burn...
Their visual acuity is generally poor, having very small eyes, and in recent times many have lenses fitted onto their pores for better focus. 360 vision is easy for a bifurcator to achieve, provided they have more than one eye.
As for their pit organs... bifurcators can see both visible and infrared. (Hence their translated morph names of "cold" colors) This helped them maintain spatial awareness in pre-industrial times when many bifurcators lived in sheltered (and thus dark) cities or caves to escape from the harsh radiation of their star.
Pit organs and eyes aren't always near each other. Oftentimes a bifurcator will have enough pits and eyepores to see in both visible and infrared all around them, but other times a bifurcator may only have eyes on one side and pit organs on the other, giving them rather strange vision.
Haven't thought too hard about how they breathe, but they might have another feathery eversible gill-like structure they can toss out whenever they need to breathe and then pull back in.
