13 different species of Chameleon, from the genus Trioceros, are to be found in Kenya. Trioceros jacksonii jacksonii – Jackson's Three-horned Chameleon, is the most widespread of these and sometimes found in Nairobi suburbs. It is also known as the "Kikuyu Three-horned Chameleon". Von Hoehnel’s Chameleon (aka High-casqued Chameleon) is another common Chameleon. Cameleons are 'Old World' (before America) Lizards, that can change colour and swivel each eye 180 degrees, providing them with all-round vision. Their eyesight is extraordinary, enabling them to view prey at great distances - and they have a tongue to match; twice as long as their body (excluding the tail). A sticky end to the tongue brings about a sticky end to flies, ants, spiders and other insects. Chameleons feet look like tongs, but do have five fingers / toes on each leg. In addition, each finger / toe has a very sharp claw, to assist them climbing along branches.
