Ghost frog
Ghost frogs are a unique amphibian species native to South Africa, known for their elusive nature and distinctive appearance. Their name is thought to derive from their rarity and the almost translucent quality of their skin, which can give them a ghostly appearance. Ghost frogs inhabit fast-moving mountain streams, where they are primarily aquatic but may occasionally venture onto land or climb nearby vegetation. They possess mottled green or brown skin with reddish markings, along with a characteristic flat body, large eyes, and long limbs that aid in their jumping ability.
These frogs typically grow to about 2.5 inches (six centimeters) in length and are carnivorous, primarily feeding on a variety of insects, including aquatic species. Reproduction occurs when females lay 100 to 200 eggs in damp areas near streams; the hatchlings emerge as free-swimming tadpoles, equipped with suckers to cling to surfaces in the current. Ghost frogs undergo metamorphosis, developing into adults as their tails are absorbed and legs formed. Unfortunately, they are classified as critically endangered, facing threats from habitat loss and human encroachment.

Ghost frog
Ghost frogs are native to South Africa. It is not known for sure why they are called ghost frogs. Ghost frogs may have been given their unusual name from the fact that they are rarely seen. Since they live in such fast-moving waters, they are only seen occasionally when the currents slow, and even then, they remind people of the way ghosts are said to appear and then vanish. Another possible reason they are called ghost frogs is that they have such thin skin on their bellies that they are almost clear, like ghostly images.

There are two genera and up to seven species of ghost frogs all found in South Africa. They are an aquatic, or water-living, family which usually remain within fast-flowing, mountain streams. Sometimes they do venture out of the water and may even be found climbing in trees and bushes near the water's edge.
Ghost frogs have mottled green or brown skin with reddish markings. They have flat bodies with long limbs, large eyes, and long fingers and toes. Like other frogs, they have long hind legs and short front legs. Their long hind legs are folded under their bodies and help them to leap and jump from place to place. The bellies of ghost frogs are almost transparent, or clear, so much so that their muscles and organs are visible through their thin skin. Ghost frogs generally grow to be about 2 1/2 inches (six centimeters) long.
Like other frogs, ghost frogs are carnivorous. This means they eat only meat. Their diet includes a variety of insects, especially aquatic insects. Sometimes ghost frogs even come out of the water to catch flying insects with their tongues.
Female ghost frogs lay their 100 to 200 eggs along the sides of the streams in damp ground or puddles. When the young hatch free from their eggs, they move into the water as free-swimming tadpoles. These tadpoles have tails which help them swim and large, rounded suckers under their heads which help them stick to rocks and stones, so that they are not washed down the stream with the current. During their first few weeks in the water, the tadpoles experience a change, or metamorphosis, in which they transform into adult ghost frogs. Their tails are absorbed into their bodies, and they grow four legs.
The life span of ghost frogs is unknown. Ghost frogs are a critically endangered species due to habitat loss and human development.
