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.

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.

With luck
About 10% of wildlife watchers report a Helmeted Turtle sighting in Ngorongoro Conservation Area on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 9 reptiles 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 30% of wildlife watchers report a Helmeted Turtle in Ngorongoro Conservation Area on a given day, against under 5% in May to January, the lowest months. That is one of Ngorongoro Conservation Area's wettest months, with about 190 mm of rain against almost none 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.
4th of 5
Of the 5 parks where we can rate Helmeted Turtle sightings, Ngorongoro Conservation Area ranks 4th at about 10%. The best odds are in Etosha National Park (Namibia, about 40%), Serengeti National Park (Tanzania, about 10%) and Masai Mara National Reserve (Kenya, about 10%).
GBIF citizen-science records
It is estimated from how often the Helmeted Turtle is recorded against all the reptiles logged in Ngorongoro Conservation Area (6 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.
