White rhinoceros
The white rhinoceros or square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that still exist. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhino consists of two subspecies: the southern white rhino, with an estimated 17,460 wild-living animals at the end of 2007 (IUCN 2008), and the much rarer northern white rhino. The northern species has very few remaining, all in captivity.
Naming
A popular theory of the origins of the name "white rhinoceros" is a mistranslation from Dutch to English. The English word "white" is said to have been derived by mistranslation of the Dutch word "wijd", which means "wide" in English. The word "wide" refers to the width of the rhinoceros' mouth. So early English-speaking settlers in South Africa misinterpreted the "wijd" for "white" and the rhino with the wide mouth ended up being called the white rhino and the other one, with the narrow pointed mouth, was called the Black Rhinoceros. Ironically, Dutch (and Afrikaans) later used a calque of the English word, and now also call it a white rhino. This suggests the origin of the word was before codification by Dutch writers. A review of Dutch and Afrikaans literature about the rhinoceros has failed to produce any evidence that the word wijd was ever used to describe the rhino outside of oral use.[4] Other popular theories suggest the name comes from its wide appearance throughout Africa, its color due to wallowing in calcareous soil or bird droppings or because of the lighter colour of its horn. An alternative name for the white rhinoceros, more accurate but rarely used, is the square-lipped rhinoceros. The white rhinoceros' generic name, Ceratotherium, given by the zoologist John Edward Gray in 1868,[5] is derived from the Greek terms keras (κερας) "horn" and therion (θηριον) "beast". Simum, is derived from the Greek term simus (σιμος), meaning "flat nosed".

Cottontop tamarin
The cotton-top tamarin (Saguinus oedipus), also known as the Pinché tamarin, is a small New World monkey weighing less than 1 lb (0.5 kg). It is found in tropical forest edges and secondary forests where it is arboreal and diurnal.
Etymology
In German-speaking areas, the cottontop tamarin is commonly known as "Lisztaffe" (literally "Liszt monkey") most likely due to the resemblance of its hairstyle with that of Hungarian composer and piano virtuoso Franz Liszt.
Physical characteristics
This tamarin species has a long sagittal crest, white hairs from forehead to nape flowing over the shoulders ("Cottontop"). The back is brown, and the underparts, arms and legs are whitish-yellow. The rump and inner thighs are reddish-orange.
It is considered one of the bare-faced tamarins because of the lack of facial hair. Its lower canine teeth are longer than its incisors, so it seems as if it has small tusks. It is about the size of a squirrel and weighs 10-18 ounces.[citation needed] The males are only slightly larger than females. A medium cottontop tamarin weighs 432 g.[5] Tamarins are among the smallest of the primates. Head body length of this species is 17 cm and tail length is 25 cm.[6] Forelimbs are shorter than the hind limbs. The thumb is not opposable and the tail is not prehensile. All the finger and toe nails are like claws except for the big toe which has a flat nail.
Communication
The cottontop tamarin vocalizes with birdlike whistles, soft chirping sounds, high-pitched trilling, and staccato calls. Researchers say its repertoire of 38 distinct sounds is unusually sophisticated, conforming to grammatical rules and able to express curiosity, fear, dismay, playfulness, warnings, joy, and calls to young.[6] It has loud territorial songs as well as songs when it is excited. It moves its tongue across the lips. This may be a recognition signal, or could be used to communicate anger or curiosity. A "threat face" consists of lowering the forehead until it forms a bulge which almost covers the eyes; the lips are pushed forward and the head and neck crests are erected. This apparently is sufficient since no other body language is used.
