Phrynus operculatus, commonly known as the tailless whip scorpion, is an arachnid belonging to the order Amblypygi. It is characterized by its elongated body, which can reach up to 8 centimeters in length, and its whip-like front legs that are used for sensory purposes. Despite its intimidating appearance, Phrynus operculatus is harmless to humans and primarily feeds on small insects. It is commonly found in tropical and subtropical regions, often inhabiting dark and humid environments such as caves or leaf litter.
