A behavioral adaptation for which the camel is famous is their reaction to the approach of a threat - they spit! By breaking up the airflow, spines create a layer of air or what could be called a microclimate that serves as insulation against changes in temperature as well as accelerated evaporation brought on by hot air or wind. Cacti have numerous anatomical and behavioral adaptations for absorbing and storing water, preventing water loss, protecting themselves from predators, limiting damage from the hot sun, saving their energy, requiring few resources, and attracting pollinators.
