What morphological feature results in the Brown Anole's less impressive climbing on slick surfaces?

Possessing claws instead of specialized lamellae pads

Foot morphology is a critical differentiator between certain anole species, directly affecting their interaction with vertical surfaces. The Green Anole is highly adept at adhering to smooth materials like glass or painted walls because its toes are equipped with specialized adhesive structures known as lamellae pads. Conversely, the Brown Anole lacks these specialized pads and instead possesses claws. While claws are useful for gripping rougher textures like bark, they do not provide the same level of adhesion on slick, manufactured, or smooth natural surfaces, thereby limiting the Brown Anole's ability to scale vertical substrates with the same ease as its green cousin.
