Here’s this month’s Creature Feature, which begins with the electric blue tails of skinks and ends with limbless lizards. It’s based on these two papers about why skinks have blue tails (1, 2) by William Cooper and Laurie Vitt, as well as this paper on the evolution of limblessness in lizards by John Weins and colleagues.
And here is one of my favourite lizards, the almost-limbless grass lizard.
