Four-Eyed Stumpworm

The four-eyed stumpworm has some major developments to its anatomy compared to its immediate ancestor, the sheilded stumpworm. To remain safe from predators, its body has shortened to the point that it is permanently in a "collapsed" state without having to expend energy, and its arms are almost always covering its soft head. The latter detail may be the reason for its most bizarre development—that is, it has evolved two pairs of primitive eyes on its arms, rather than on the actual head which they are guarding. This allows it to sense light, dark, and movement without leaving any part of its body vulnerable to attack. It dwells in the leaf litter of Sagan's forests. It has also evolved articulated claw-like extensions of its arms serving as mandibles, which it uses to puncture the bark at the bases of purple bubble trees so that it can feed on the fluids within.
