This process accounts for only a few seconds to hours.Ī sudden fluctuation in the density of pigment-containing granules causes this rapid change. It is initiated by the stimulation of several intrinsic body factors or extrinsic environmental factors. It mainly takes place at the onset of the first mating season. This morphological change stays for either one mating season or a lifetime. In this outer layer, a notable change takes place in the density of pigment-containing cells. The outer layer of the skin is called Chromatophore. The process can take several days to several months. During a phase in a tree frog’s life cycle, it changes its color permanently. The Permanent color change occurs morphologically. So the color change mainly ranges from Green to brown. These outlines may vary from species to species, but features two main patches, green or brown. The upper shell of their coat has a marked outline that resembles lichen. These layers allow the transformation of colors in their skin. Their color changing is stimulated by various extrinsic factors, but initiated and controlled by the three layers of pigment present in the frog’s epidermis. The epidermis of the frog’s skin plays the most vital role here. Pigmented Skin Plays The Main Role In Changing Tree Frog’s Color There are almost 39 species of Dichromatic Tree frogs. The Rhacoporus is a genus of Rhacophoridae, which comprises two genera Leptomantis and Zhangixalus. The name Hyla is derived from Latin, which means ‘Variable color’. The red-eyed tree frog mainly belong to the Family Rhacophoridae and Hylidae. Most of their physiologic and behavioral instincts are firmly associated with color changing. This change can be either temporary or permanent. They cannot change the color of their skin under different situations even if it’s essential.ĭichromatic frogs have the ability to change color at least once in their entire life cycle. Monochromatic frogs do not possess the ability to change colors. Frogs can be classified into two classes based on color change.
