Leiosaurus: big heads, bold patterns

I like iguanian lizards – who doesn’t? Among the enormous number of taxa that you hardly ever hear anything about is the endemic Argentinean taxon Leiosaurus, type species of Leiosauridae.

THE AMAZING WORLD OF SALAMANDERS

THE AMAZING WORLD OF SALAMANDERS

Tet Zoo loves amphibians* (that’s anurans, salamanders, caecilians and their close relatives), and since 2008 I’ve been making a concerted effort to get through all the amphibian groups of the world.

The troubling lack of Platyhystrix images online: the Tet Zoo Solution
