Eyes That Mark the Forests

Male Calumma parsonii show population‑specific eye‑turret coloration across their fragmented humid‑forest range. Each forest block produces its own stable chromatic signature in adult males: 

Calumma p. cristifer carry bright or dull green eyes.

Coastal northeast animals carry the classic orange‑eye phenotype. 

Vohimana and Anosibe an'Ala males show the yellow‑giant palette with warm yellow tones 

Ranomafana males express the yellow‑lip pattern with green turrets and yellow lips. 

Masoala males are the green‑giant form with saturated green turrets. 

These color systems are consistent within each locality and reflect long‑term isolation of lineages.
