Other West African Reptiles

Geckos are just one of the many desert crawlers in Senegal. Lizards are common, often sunning themselves on the sides of buildings, or scampering out of your way on the sidewalk. Most are non-descript grays and browns, but at least one species is striking in it’s coloration: it has a school bus yellow head, steel blue body, and a gray and yellow tail.

Once while birdwatching, I came across what appeared to me to be a salamander, small and quick with soft-scaled green skin on the back, with a white underside. There were two: one had nearly fluorescent orange sides. The other—its mate?—had white sides.

Our students’ favorite species (probably because they can catch them), is chameleons. These are quite different from the lizard-like color-changers that frequented my grandmother’s yard in Alabama during our summer visits decades ago. I would be hard pressed to accurately describe the Senegalese versions, except to mention that their tails can curl tightly up over their backs, or around a small tree branch for stability, that they have three-toes on their feet, and that they change colors from green to brown.

Finally, there are a few snakes, but they are not common. In fact, I don’t think I’ve ever seen a wild snake here. The school has a 6-foot boa named Spot, but he’s an émigré. He was donated to the school by his former owner, a woman who brought him to Senegal when she was evacuated to Dakar during the Ivory Coast’s civil war a few years ago. She snuck him in by hiding him under her sweater and pretending she was pregnant! Yes, really!

Oops. Almost left out crocodiles and monitor lizards, both of which I've seen in zoo-like parks and in the wild.

This ends part two of your ____________* lesson for today.

*Does anyone know the scientific Latin term goes in that blank?
