Calumma is a genus of chameleons . All species in this genus are endemic to Madagascar .
Appearance
The genus Calumma includes small to large chameleons. These animals have a distinctive coloration and the ability to change color significantly. In Calumma occurs sexual dimorphism on: males have clearly developed structures on the head, which are absent in the females or are at least less pronounced. These are, for example, nasal processes, helmet-like structures and occipital lobes. The latter are skin-like, splayable growths on the side of the skull. Male Calumma also grow larger than female conspecifics, and they have a longer tail than the female with a thickened base.
Outwardly, this genus is difficult to distinguish from Furcifer . In many Calumma occipital lobes are present, in Furcifer not. In Calumma there is also no pronounced crest on the ventral side (rudimentary in C. brevicorne ), but such a ridge often occurs in Furcifer .
Occurrence
The genus Calumma is endemic to Madagascar. The only exception was the species C. tigris , which occurs in the Seychelles , but was placed in the genus Archaius in 2010 . The genus Archaius , already described in 1865, was revived.
These are exclusively arboricolous species that have so far only been detected in humid areas. Calumma occurs up to over 1900 m altitude - another distinguishing feature to Furcifer ; of the species of this genus, only F. campani inhabits these heights. With a few exceptions, Calumma species show a preference for undisturbed forests.
Systematics
Since the generic name Calumma is no longer regarded as female but as a neuter, some name endings have changed.
