Underwater “traffic” encompasses a fascinating variety of creatures, from fish with their graceful swimming postures to jet-propelled jellyfish and remoras hitching rides on other organisms. Among these, a remarkable species known as the “underwater gecko,” the rock-climbing fish (Beaufortia kweichowensis), stands out. This extraordinary creature possesses a unique set of abilities—it can swiftly slide along underwater surfaces like an ice skater, crawl against water currents, and securely adhere to a fixed position with remarkable adhesion force.
