Insights Into Spatial Orientation and Cognition in Tarantulas (Araneae: Theraphosidae) Under Natural Conditions, With Notes on Possible Ontogenetic Niche Shifts

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Cognitive studies on spiders have largely ignored mygalomorphs, such as tarantulas, and almost completely lack field‐based observations. We present nine observations of arboreal and fossorial New World tarantulas, including a blind cave‐dwelling species, providing evidence for possible experience‐based navigation and spatial learning during foraging ...
