Have you ever seen a turtle that looks like it’s wearing an oversized helmet? That’s the Madagascar Big-headed Turtle (Erymnochelys madagascariensis), one of the most fascinating freshwater species you’ve probably never heard of. As one of Madagascar’s only two native turtle species, this turtle is key to its ecosystem, with interesting eating habits and defense mechanisms.
The Madagascar Big-headed Turtle belongs to the Podocnemididae family, an ancient group of side-necked turtles. What makes them special? Unlike most turtles, they don’t pull their heads straight back into their shells – they tuck them sideways instead!
Called “Rere” by local Malagasy people.

The Madagascar Big-headed Turtle is more than just another species. It’s a key part of Madagascar’s ecological balance. While they don’t have venom or special defenses, they’re essential for healthy water environments. Their survival is at risk, but with increased awareness and conservation efforts, we can change this by spreading the word and working to protect them. Every species is important, and losing one can harm the whole ecosystem.
