Sauceback

Saucebacks are bipedal fauna that descended from Worms.

Breathing & Blood
Saucebacks breathe using microlungs along the flank of the tail that are designed to take in oxygen. The ancestor of the saucebacks had pores all over the body. Saucebacks have an iron based blood which makes it red.

Diet & Energy
Saucebacks eat using a toothy radial mouth. Ones on Wright have tusks to stab or grab their prey with, while ones on Glicker have four jaws to bite with. Saucebacks commonly hunt large game, which they are adapted for.

Senses
Saucebacks' primary sense is echolocation. They have bat-like ears. Saucebacks lack eyes, but they can still "see" sound. One species of sauceback evolved an infared-receptor on the forehead, but it can only sense it at a close range. All saucebacks have a very strong sense of smell. They typically use this to seek out prey from long distances. To smell, they have moist olfactory patches around the mouth.
