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
Northern pygmy salamander Northern pygmy salamander The northern pygmy salamander (or northern pigmy (sic), "Desmognathus organi") is a terrestrial species of salamander in the family Plethodontidae and genus "Desmognathus". Along with the southern pygmy ("D. wrighti") and the seepage salamander ("D. aeneus"), these are some of the smallest salamander species in North America and can be found in higher elevations in the southern Appalachians. "Desmognathus organi" can be identified by its small size, averaging only 40–60 mm total length, and its distinct herringbone pattern on the dorsal side and copper colored eyelids, which are traits only shared with "D. wrighti". Dorsal coloration can
