Spike Berry plants grow in the mid range of the exposed caves. The main part of the plant consists of a stiff yellowish stalk. The stalk is rigid in order to prevent animals from getting at its delicious berries, which grow near the base of the stalk. The plant grows in small cracks or ledges, sending its roots into the cracks for support. When the berries are ripe enough, they turn hard and dry out. Once they reach a certain level of hardness, they pop, releasing many tiny seeds, which have small hairs on them to carry them in the wind. When the seed lands somewhere, it will start to grow, but only if it comes in contact with water.
The sap hammer is a small climber of trees, about 20 centimeters long. They spend their whole lives on the surface of the cliff trees. In order to reach the sap, which they eat, they hammer their mouth repeatedly in the same spot. They reproduce in the same three-gendered way as most vertebrates. They lay their eggs in nests made mostly of soft leaves in places where the trees are semi-level. They lay one or two eggs each in the nest and they share care of the eggs until they hatch. Once hatched, the parents will feed it sap by carrying it in a small pouch in its throat, spitting it back out into the young mouths. The young have to lay on their backs to be fed, because of their down-turned beaks.
Skullface are carnivorous animals with a large bony beak meant for tearing into the flesh of its prey. About 40 centimeters long, and just as tall, the skullface are gliders. They have sharp claws, which are used for clinging to bark, not for killing prey. They eat mostly small animals, gliding in at high speeds to crush their prey with their strong beaks. They have excellent eye sight, using their forward eyes to pick out prey, and their side-facing eyes as peripherals. Reproducing in the same three gendered way, they lay their eggs on top of ledges. When the eggs hatch, they young stay in the nest, the parents feeding scraps from recent meals. The bright color of the beak is uses as a way to impress mates, and also to warn other creatures.
