Corsican painted frog, Discoglossus montalentii
The Corsican painted frog is found only on the French island of Corsica in the central mountainous areas from 980 to 6,200 feet in elevation. This species lives both in still and flowing waters and is very agile leaping from rock to rock. The Corsican painted frog is a nocturnal species that will sit in shallow water with only the head above the surface.
The Corsican painted frog’s slender body is smooth, shiny, and covered with small warts. This species has two distinct color patterns — one being a solid dark brown, grey, or a reddish brown, while the other has dark brown spots. The belly is yellowish-white. The male of this species has a musical call described as a rolling harmonious laugh. The average length of this species is 2.6 inches.
The tadpole of the Corsican painted frog has a tail longer than the body with a rounded tip. The color is dark brown or black.
The diet of the Corsican painted frog consists mainly of aquatic insects, crustaceans, worms, and spiders.
Breeding occurs in shallow water with the male grabbing the female around the waist. The female will lay 500 to 1,000 eggs in the water under rocks and stones. The male will then fertilize the eggs. The eggs are dark in color with a diameter of 0.039 to 0.059 inches and covered with a thick gelatinous casing. The tadpole will develop in the water for three to eight weeks before metamorphosis begins.
The population of the Corsican painted frog is in slow decline mainly from the introduction of other predatory species into the region. This species is near threatened on the Endangered Species list.
