Description ( 英語 )

由AmphibiaWeb articles提供
A Hyperolius from coastal KwaZulu-Natal; males are small (to 22 mm), females to 29 mm. Phase J: light to dark brown with a dark-edged silverish canthal and dorsolateral stripe, sometimes brown with dark spots and with a light spot on the heel, thus almost indistinguishable from H. mitchelli from further north. Phase F: dorsum brilliant green separated from the light yellow to white ventrum by a distinctive irregular margin. Sometimes with a light lateral line. Ventrum off-white and smooth, concealed surfaces of limbs, feet and digits pale or colourless. Pupil horizontal.Tooth formula of tadpole 1/1+1,2.This species shows developmental changes in patterning, with two phases, J (juveniles and many mature males) and F (mature females and some mature males). All newly metamorphosed individuals are phase J, which is normally brownish to green with paired light dorsolateral lines, or an hourglass pattern. All females, and some males, develop into phase F before the first breeding season. Phase F is often colorful and variable, showing the diagnostic color characteristics for the species or subspecies. Either well-defined morphs may be present, or graded variation.

由AmphibiaWeb articles提供
Males call from elevated positions in dense vegetation, often Cyperus, and remain well-concealed. The voice is a very soft cricket-like chirp repeated at irregular intervals with a frequency-intensity maximum at 3000 cps.The eggs are apparently placed above water. The jelly is clear and the eggs have a brown and white pole.

Pickersgill's reed frog ( 英語 )

由wikipedia EN提供

Pickersgill's reed frog (Hyperolius pickersgilli), also known as Avoca reed frog, is a species of frog in the family Hyperoliidae. It is endemic to South Africa.[1][3][4] It occurs in the coastal lowlands of KwaZulu-Natal between Sezela and St Lucia.[1]

Description

Adult males grow to usually no more than 22 mm (0.9 in) whereas adult female can approach 30 mm (1.2 in) in snout–vent length. The snout is acutely pointed. The tympanum is hidden. The toes are webbed. There are two colour phases. Juveniles and males are dorsally light to dark brown. There is a dark-edged, white to silver canthal stripe that passes round the snout, over the eyes, and then continues dorso-laterally to the groin. The feet and concealed parts of the limbs are yellow, while the throat and the ventrum are yellowish to white. Females change to the female colour phase at length of 20–22 mm (0.8–0.9 in). The dorsum becomes green, eventually light to yellowish green, whereas the dorso-lateral stripes become indistinct and eventually disappear. The light yellow to white ventral colouration is separated from the dorsal colouration with a distinct irregular margin.[2]

Males have a gular vocal sac that has a well-developed protective flap over it. The male advertisement call is a quiet slow creak that could be mistaken for an insect call.[2]

Hyperolius pickersgilli female green form

Habitat and conservation

Pickersgill's reed frog is a habitat specialist that mainly occurs in Indian Ocean Coastal Belt "Vegetation Group 2", at elevations up to 380 m (1,250 ft) above sea level. It requires perennial wetlands that have very dense reed beds. This habitat type is highly endangered and poorly protected. The species occurs in the iSimangaliso Wetland Park, Umlalazi Nature Reserve, Ongoye Forest Reserve, and Twinstreams-Mtunzini Natural Heritage Site.[1]
