M 29-30 mm, F 32-35 mm. Tibiotarsal articulation reaches at least the nostril and often beyond snout tip. Hand with some webbing, foot webbing 1(0), 2i(0.5), 2e(0), 3i(0.5), 3e(0), 4i/e(1), 5(0). Dorsal skin smooth. Dorsally usually greenish, sometimes with small or larger interspersed reddish dots. Especially subadults and at night, specimens can change colour to become more reddish brown. Outer iris area distinctly blue, iris periphery blue.

Similar species: The remaining species of the B. rappiodes-group are smaller and differ by iris colouration. Species of the B. luteus-group have white lateral fringes along the lower arm and tarsus.

Life History, Abundance, Activity, and Special Behaviors

Habits: Males call at night from perches in the vegetation 1-2 m above the ground, along relatively slow-moving streams and ditches. During dry weather, calling specimens have also been observed up to 5 m high. One amplecting pair laid 154 dark brown eggs.

Calls: Consist of two unharmonious and pulsed note types. The longer note type contains up to 40 pulses and is sometimes repeated in short series. The shorter note type consists of three, rarely four pulses, and is usually emitted in series of 2-3 notes.

Breeding takes place in streams (Nussbaum and Andreone 2008).

Green bright-eyed frog

The green bright-eyed frog,[2] Boophis viridis, is a species of frog in the Mantellidae family endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.


Contents

Characteristics[edit]

The average size of the males reaches 29 – 30 mm, while the females can grow to about 32–35 mm. The hands and feet are webbed. Their dorsal skin is known to be smooth and green in color, sometimes with reddish spots, as well. They also have the ability to change colors and become more reddish-brown. Their inner and outer irises are blue.[3]

Habits[edit]

Males use their call at night while in vegetation about 1–2 m above the ground, along streams, and also by ditches. When the weather is dry, a calling green bright-eyed frog has also been found up as high as 5 m. The calls are a combination of two inharmonious note types that include a long note repeated in short pulses and a shorter note consisting of three repeated notes.[3]

Breeding[edit]

Breeding takes place in streams. One pair of frogs can have as many as 154 dark-brown eggs.[3]

Population[edit]

The species is not currently threatened. The reasons for possible decrease in population include:

  • General habitat alteration and loss
  • Habitat modification from deforestation, or logging-related activities
  • Intensified agriculture or grazing
  • Urbanization
  • Habitat fragmentation[3]
