Classification
The Serrated Hinged Terrapin belongs to the suborder Pleurodira (side-neck turtles) and the family Pelomedusidae. It is a family of African side-neck turtles that, like other pleurodires, fold the neck to the side instead of pulling it straight in. Its scientific name is Pelusios sinuatus.
Appearance & Distinguishing Features

Habitat & Distribution
They are found across sub-Saharan Africa in rivers, lakes, pans, and seasonal pools, often in still or slow water.
Diet & Feeding
They are omnivorous, eating insects, molluscs, fish, carrion, and plant material, and will aestivate in mud through dry spells.
Behavior & Conservation
They can survive long dry periods by burying in mud and lowering metabolism. Some species are kept as hardy, readily available pet turtles.
Popularity & Recognition
