Meller’s Chameleon
Trioceros melleri, with the common names Meller's Chameleon and giant one-horned chameleon, is the largest species of chameleon from the African mainland. John Gray, a biologist and taxon authority, mentions "Dr. Meller" in the section of his 1865 description concerning the habitat of the species, which gives the Meller's chameleon both its common and scientific names.
Huge male T. melleri, the largest chameleon from the continent of Africa, generally grows to a length of 24 inches (61 cm), but exceptionally large individuals have reportedly grown to a length of nearly 30 inches (76 cm) and weighed 21 oz (600 g). The chameleon's sides are covered in large horizontal bands and spots that might be brown, dark green, yellow, or even black. The creature has deep forest green and white stripes as its base color, but like many chameleons, it is capable of changing these colors in response to different environmental factors. When being handled or fed, they may exhibit black and white spots.
