The African helmeted turtle (Pelomedusa subrufa), also commonly known as the marsh terrapin, the crocodile turtle, or in the pet trade as the African side-necked turtle, is a species of omnivorous side-necked terrapin in the family Pelomedusidae. The species naturally occurs in fresh and stagnant water bodies throughout much of Sub-Saharan Africa, and in southern Yemen.
The marsh terrapin is typically a rather small turtle, with most individuals being less than 20 cm (7.9 in) ranging from 15 to 21 centimeters in straight carapace length, but one has been recorded with a length of 32.5 cm (12.8 in). It has a black or brown carapace. The top of the tail and feet are a grayish brown, while the underside (plastron) is yellowish.
The male turtle is distinguished by its long, thick tail. A female tends to have a shorter tail and a broader carapace. A hatchling has a shell size of about 3 cm (1.2 in) in length, and is olive to black in color. It also has two small tubercles under the chin and musk glands in the sides of the carapace.
Uniquely, the genus Pelomedusa does not have a hinged plastron (lower shell). All the other species in the family Pelomedusidae, however, do... Wikipedia →

No species of the same family or order lives in Serengeti National Park, so these are its closest relatives here: other reptiles.
With luck
About 10% of wildlife watchers report a Helmeted Turtle sighting in Serengeti National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 11 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Helmeted Turtle in Serengeti National Park on a given day, against under 5% in May–July and December, the lowest months. That is one of Serengeti National Park's wettest months, with about 140 mm of rain against 5 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Helmeted Turtle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 parks where we can rate Helmeted Turtle sightings, Serengeti National Park ranks 2nd at about 10%. The best odds are in Etosha National Park (Namibia, about 40%).
GBIF citizen-science records
It is estimated from how often the Helmeted Turtle is recorded against all the reptiles logged in Serengeti National 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.
