Sclerophrys garmani, also known as Garman's toad or eastern olive toad (among others), is a species of toad in the family Bufonidae. It is widely distributed in East and Southern Africa. However, populations north and south of Tanzania might represent distinct species. If so, the name Sclerophrys garmani would apply to populations from northeastern Africa. Furthermore, its southern boundary towards the range of Sclerophrys poweri in South Africa is also unclear.
The specific name garmani honors Samuel Garman, an American ichthyologist and herpetologist. Males grow to 106 mm (4.2 in) and females to 115 mm (4.5 in) in snout–vent length. The tympanum is almost as big as the eye diameter. The parotoid glands are large. The back is tan to olive-brown and bears large paired markings edged with black. A thin vertebral stripe may be present. Dorsal skin has distinct warts that bear small, black spines. The ventrum is off-white.
The male advertisement call is a loud, low-pitched "kwaak", lasting for about a second. The range extends from Ethiopia and Somalia southward through Kenya, Tanzania, Mozambique, Zambia, Zimbabwe, Botswana, to South Africa... Wikipedia →

With luck
About 10% of wildlife watchers report a Garman's Toad sighting in iSimangaliso Wetland Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 22 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 and November
In those months about 20% of wildlife watchers report a Garman's Toad in iSimangaliso Wetland Park on a given day, against under 5% in February, May, July and September–October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Garman's Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
3rd of 3
Of the 3 parks where we can rate Garman's Toad sightings, iSimangaliso Wetland Park ranks 3rd at about 10%. The best odds are in Gonarezhou National Park (Zimbabwe, about 30%) and Kruger National Park (South Africa, about 20%).
GBIF citizen-science records
It is estimated from how often the Garman's Toad is recorded against all the amphibians logged in iSimangaliso Wetland Park (12 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.
