Interesting topic on a facebook group recently about stripeless tree frogs in the Canary islands. (Lanzarote) They seem to be smaller and brown like this….
This is interesting because if on mainland Spain has two species why aren’t the ones on the Canary islands at least considered to be subspecies? is it just that they haven’t been studied further?
Researchgate has a project published about the color differences but for a different island (Alegranza) not Lanzarote. Its really about stripeless tree frogs having stripes though 🙂
