In the animal kingdom, specifically among dolphins and chimpanzees, individuals have been observed using tools. Dolphins in certain regions use sponges as tools to protect their snouts while foraging for food on the ocean floor. They wear the sponges like a protective "mask" to prevent abrasions. Similarly, chimpanzees have been observed using sticks as tools to extract insects from trees or as weapons for hunting. This showcases the fascinating intelligence and adaptability of animals in utilizing objects as tools to aid them in various tasks.
