於南非和 納米比亞,主要自然棲息地為 亞熱帶或 熱帶的乾旱灌木叢和沙灘,它們的物種延續正受到棲息地消失的威脅。

特徵

納馬雨蛙有著矮胖的身軀,短小精悍的頭部,頭上長著大得不成比例的眼睛,扁平的臉和窄小的嘴。四肢短小,腳趾上沒有蹼和吸盤。身體上半部的表面主要為深棕色夾雜著淺棕色和奶油色斑塊,斑塊匯集在脊柱附近,腹部為白色、平滑。但它的皮膚是半透明的,沿著下顎的喉部區域復蓋著黑色斑點。成年納馬雨蛙可以長到46mm。

生活習性

這種雨蛙就像台挖掘機,一生中的多數時間都躲在地下,也不棲息於水中。主要集中在乾旱、半乾旱的灌叢植被沙地中——但在壤質和岩石基質的丘陵地帶也有發現。當被驚擾時,它們的身體就會像那位要”成為海賊王的男人“一樣鼓脹成一個氣球,以防禦捕食者。在春、夏、冬都有它們的繁殖活動紀錄。大部分時間它們都呆在地下休息,在雨後會到地面捕食昆蟲。

The Namaqua Rain Frog has a squat, round body with a short, narrow head which has relatively large eyes, a flat face and narrow mouth. The limbs are short and stumpy and the fingers and toes lack webbing and adhesive discs. The upper body surface is brown with lighter brown to cream patches on the back and sides. These patches are occasionally fused together and may include irregular pairs of paravertebral patches. The underside is mainly smooth and white, but the skin is translucent in parts, and the throat area may be granular with dark markings around the jaw line.

This frog is a burrowing species that spends most of its time underground and does not inhabit water. It occurs generally in dry, low-lying areas that are predominantly sandy and well covered with scrub vegetation - but has also been recorded in hilly areas with more loamy and rocky substrates. When disturbed, these frogs have the ability to inflate their bodies dramatically as a defence mechanism to deter predators. Breeding activity has been recorded in winter, spring and summer. They spend most of their time underground, surfacing after the rains to feed on insects.
