Green anole: what a study on a tropical cousin reveals about its cognitive abilities
The green anole (Anolis carolinensis) has long been seen as a lizard with largely stereotyped behaviour, rarely discussed in terms of cognitive enrichment. A study by Leal and Powell, published in 2012 in the journal Biology Letters, tested several cognitive abilities in a closely related tropical anole, Anolis evermanni from Puerto Rico, with results that invite a rethink of behavioural needs across the whole Anolis genus, which includes the green anole (research on Google Scholar).

A problem designed to test flexibility
Researchers presented six anoles with a two-well apparatus, only one containing food, with the rewarding well gradually covered by a moving blue disc until access was fully blocked. Solving it required working around the obstacle rather than pushing straight at it, a task few researchers expected a small lizard to master.
Results that rival some birds
On average, the anoles tested solved the problem in three fewer attempts than birds faced with comparable tasks in other studies, using several different strategies and showing rapid associative learning. This behavioural flexibility contradicts the assumption of a rigid repertoire in small diurnal lizards.
What this means for your green anole
While Anolis evermanni is not the green anole itself, the two species share a closely related cognitive and sensory setup within the same genus. Introducing variety into the enclosure — new perches, hides moved around regularly, live prey offered in changing ways — gives the animal a chance to exercise exploration and problem-solving abilities that its captive routine rarely calls on otherwise.
What this does not change about the basics
This cognitive enrichment remains a complement, not a substitute for the already well-documented physiological needs of the green anole: temperature, humidity and UVB still come first over behavioural stimulation whenever budget or space is limited.
- Apparatus tested: a food well gradually blocked by a moving disc.
- Notable result: solved on average faster than birds on comparable tasks.
- Relevance to the green anole: a closely related species, similar cognitive setup within the Anolis genus.
- Priority: basic physiological needs still come before cognitive enrichment.
This enrichment angle complements our guide to setting up a green anole terrarium, and connects with our notes on group cohabitation, another factor shaping its everyday behaviour.
FAQ
Can a green anole really learn to solve a problem like in the study?
The study covers a closely related species, not the green anole directly; it suggests a comparable ability within the genus without demonstrating it in this exact species.
Does stimulating a green anole cognitively require special gear?
No, varying the placement of items already in the terrarium is usually enough to create this stimulation.
Does this enrichment replace UVB and humidity needs?
No, those physiological parameters remain the priority; cognitive enrichment adds to them, never replaces them.
