Pygmy hippopotamus unusual secretion as common hippos, that gives a pinkish tinge to their bodies, and is sometimes described as "blood sweat" though the secretion is neither sweat nor blood. 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
East Brazilian pygmy owl East Brazilian pygmy owl The East Brazilian pygmy owl ("Glaucidium minutissimum"), also known as least pygmy-owl or Sick's pygmy-owl, is a small owl in the typical owl family. It has been argued that the here used scientific name actually belongs to the Pernambuco pygmy owl, in which case the East Brazilian pygmy owl should be referred to "G. sicki" (König & Weick, 2005). This has not gained widespread recognition. Formerly, this species included the Colima pygmy owl, Tamaulipas pygmy owl, Central American pygmy owl, subtropical pygmy owl, and Baja pygmy owl as subspecies. This species has a very large range.
