Origin of the species name:<\/h4>\n

The Belgian zoologist George Alber Boulenger, at that time working at the Natural History Museum in London (Great Britain), named this chameleon species after its nose. It was thought at the time that the species belonged to Brookesia<\/em> – and for them, appearance and nose were very unusual.<\/p>\n

Distribution:<\/h4>\n

This species is found in Ranomafana and Andohahela national parks and in the Andringitra Mountains. So far, the sites are mainly located in rainforests in southeastern Madagascar. In the National Park Ranomafana the animals occur at about 1000 m a.s.l. and higher, in the National Park Andringitra at altitudes between 1580 and 1640 m. It is difficult to find Palleon nasus<\/em>, however, and even at night, you need some luck to discover a sleeping animal of this species in the bushes. If one finds, it usually concerns pairs, with which both animals are to be found within maximally one square meter. They like to sleep headfirst on extremely thin grasses or branches, both vertically with the head down hanging or with the belly up hanging horizontally. The sleeping places are partly up to two meters above the ground.<\/p>\n

Appearance & size:<\/h4>\n

With a total length of only 9 cm, these chameleons are rather small. Females reach maximally 6,5 cm. Like almost all leaf chameleons, Palleon nasus<\/em> is beige to brownish colored with few variations. From time to time, you can find specimens with a dark lateral stripe. The dorsal crest of the male is wavy in shape, while that of the female is fairly smooth. In accordance with the name, the snout of these chameleons is elongated and pointed and ends in two small, adjacent conical scales on the nose. Incidentally, these two elongated conical scales on the nose are the easiest way to distinguish them from Palleon lolontany<\/em>. The males of Palleon nasus<\/em> have a double row of tubercles on the dorsal crest, the females only a single one.Males wear a double row of tubercles along the dorsal ridge, females only a single row.<\/p>\n

Good to know:<\/h4>\n

In 2013, the species was placed in genus Palleon<\/em> by Glaw, Hawlitschek, and Ruthensteiner taxonomically. Until then, it was thought to be a Brookesia<\/em>. The examinations suggest that it might be a sister genus of Brookesia<\/em>, that might have developed far earlier than thought. It is possibly one of the most “original” species. Palleon nasus<\/em> can be split into two subspecies, Palleon nasus nasus<\/em> (pictures) and Palleon nasus pauliani<\/em>. The latter subspecies might be restricted to Andringitra mountains, has more heterogenous scalation and lacks double row tubercles on the dorsal ridge. Up to date, it is unclear whether the subspecies pauliani<\/em> is really a subspecies of Palleon nasus<\/em>.<\/p>\n\t\t\t\t\t\t
