Trioceros werneri
Trioceros werneri, the Wemer's chameleon or Wemer's three-horned chameleon, is a species of chameleon that is endemic to forests and nearby gardens at altitudes of in the Eastern Arc Mountains of Tanzania. The adult male has three distinct "horns", whereas the female has no or only a single short horn on the nose. Like many Trioceros species of highlands, the female T. werneri does not lay eggs, but instead gives birth to live young, typically 15–20 at a time.
Taxonomy
The three long annulated horns in the male T. werneri makes it superficially similar to T. jacksonii and T. johnstoni, and to extent also to the short-horned T. fuelleborni and the smooth-horned T. oweni, but they are not close relatives.Although currently recognized as a single relatively widespread species, it is considered likely that T. werneri is a species complex and a taxonomic review is necessary.
