Morphological analysis uncovers the lance-shaped rostral appendage in male Calumma pinocchio, indicating distinct evolutionary divergence from sister species.
Deep in the lush rainforests of central eastern Madagascar, where waterfalls whisper secrets and ferns dance in the mist, lives achameleon so flamboyant it could moonlight as a carnival performer. Calumma pinocchio Glaw & al., 2025, the so-called Pinocchio chameleon, is a small but spectacular species whose males sport a lance-shaped rostral appendage — long, flexible, and often dazzlingly decorated in hues of green, blue, and red. It is as if evolution handed them a paintbrush and said, ‘Go wild.’ It is a recently described sister species of the already 150 years known Calumma gallus (Günther, 1877).But why such a nose? To answer that, we must turn to fiction.
