The dangling limapin replaced its ancestor the limapin in Badger Limestone Caverns. After millions of years without sunlight it went blind and lost all its pigment. It is pinkish in color from its red blood. Now without its sight it had to develop a new strategy to catch prey. It hangs upside down from the ceiling and dangles its long arms. Its other 4 limbs have strong suction cups like its ancestor so they stay stuck to the ceiling. They need not move very much and thus conserve energy as they wait. Once something knocks against their 2 dangling arms they will grab it with their 3 fingered hands and quickly bring it up to their beak. They have a poisonous bite which causes its prey to become paralyzed quickly. This keep its prey from shaking it off the ceiling or even injuring it while it feeds.
The vocal sac has moved to the top of the head so it faces downward. This allows it to use primitive echolocation where it can detect anything below it. However it will only use this once an while since prey are scared off by the sounds. However it comes in handy if the prey is using echolocation and it can pin point the source of the sound. They also use this to call for a mate. Like their ancestors they have 2 sexes; a donor and a carrier. They also still have viviparous birth.
