Designed for my Exploring Scifi class with Sophia Brueckner:
Red Back Sloth, is a slow moving predator that spends its life in the canopy above, it creates snare traps from its abdomen similar to the "Red Back Spider". It's prey consists of larger meals like tigers or bears, but will general eat whatever gets caught. It is not a strong predator, so it will wait out its meal's strength using its extraordinary slow metabolism.
Gulper Bat, it's echolocation is used for both sight and as a weapon, paralyzing its prey with ultrasonic sound waves. Using its tail to scoop up prey, it never lands on the ground.
