The Mozambique ridged frog (Ptychadena mossambica, also known as the broad-banded grass frog, Mozambique grass frog, Mozambique grassland frog, or single-striped grass frog) is a species of frog in the family Ptychadenidae. These frogs can swim fairly well, jump far and can crawl with ease through dense plants. Their strong hindlegs can launch them up to three metres into the air in a single bound.
Named after Mozambique where the species was first identified. Not threatened. Length: 45–50 mm, maximum 53 mm Body Internarial distance greater than snout-nostril distance. Above Dark grey-brown to chocolate brown or green. A broad creamy to orange-brown vertebral band from snout to vent, bordered by elongated blackish spots. Snout without prominent pale triangle, not paler than rest of body. 6 or more dorsolateral skin ridges prominent, continuous only as far as the hump of the back and creamy-white. Dark brown blotches, smaller than eye, between vertebral bands and dorsolateral ridges.

With luck
About 10% of wildlife watchers report a Mozambique ridged frog sighting in Kruger National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 28 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Mozambique ridged frog in Kruger National Park on a given day, against under 5% in July–August and October, the lowest months. That is one of Kruger National Park's driest months, with about 20 mm of rain against 110 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Mozambique ridged frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Mozambique ridged frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mozambique ridged frog is recorded against all the amphibians logged in Kruger National Park (42 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
