{{RandomExtant|Lumenocula|a jewel-eyed sauceback}}'''Jewel-eyed saucebacks''' are a subgroup of [[sauceback]]s in the
==Anatomy==
Line 8:
Their namesake are their eyestrils. Derived from the scent pits found in all beastworms, they are used for both sight and smell. The pupil is open to allow air in, and as this constraint prevented them from evolving lenses, they instead focus light using mirrors at the back of the eye. In effect, the entire eye is a highly efficient tapetum lucidum which reflects and focuses light into a photoreceptive patch on the inside next to the pupil hole. This causes them to appear to have white pupils, and if you were to look into a jewel-eyed sauceback's eyes, you would see exactly what it sees reflected back at you. The eye itself is stretched and squashed to focus and to push out old air, and the external part of it is featherless and rubbery. As having an open eye makes it prone to particles and small fauna becoming trapped inside, jewel-eyed saucebacks produce tears which they then remove from their eyes using the centrifugal force generated by shaking their heads like wet dogs.
In basal jewel-eyed saucebacks, the spiracles and microlungs are partially supported by chitinous shells called ceres. These are inherited from their

====Flight====
Flight-capable species of the subclass Sceloptera have highly muscular legs and large keels derived from the front protrusion of their cephalopelvis, which supports their massive wing muscles. Like bats, they also have muscular backs for pulling their wings up. Their hips are also more flexible, as necessitated by the use of their legs as wings, though this comes at the cost that the protrusion which supports the pillar-erect posture of other species is tilted
The muscles on the chest and back for flapping their wings attach to the femur.
