This substance, hipposudoric acid, is believed to have antiseptic and sunscreening properties. The skin of hippos dries out quickly and cracks, which is why both species spend so much time in water. The skeleton of "C. liberiensis" is more gracile than that of the common hippopotamus, meaning their bones are proportionally thinner. The common hippo's spine is parallel with the ground; the pygmy hippo's back slopes forward, a likely adaptation to pass
Cloud-forest pygmy owl prone to natural fragmentation. Thus, like other species that are tied to cloud forest, it is known only from a very small range. It is found in low densities in the canopy and middle stratum of forest. Nevertheless, it can descend into the understory for feeding. In common with other species of pygmy owls, this species is quite diurnal, and consumes both invertebrates and small vertebrates. Nevertheless, owing to its small size and retiring habits -generally being perched in dense evergreen trees- it is not often noticed. The cloud-forest pygmy owl breeds principally between February and June. This fact allows
