Octopus is a soft-bodied, eight-armed mollusc of the order Octopoda. Around 300 species are recognized and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the arms (which are sometimes mistakenly called “tentacles”). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight arms behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviorally diverse of all invertebrates. — Wikipedia

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 […]

Shape and color changing are key survival traits for many animals. Chameleons can change their body to hide from predators, to reflect their moods, or even to defend their territory, while some soft-bodied animal-like octopuses, squids, and cuttlefish can change both their color and shape to signal or camouflage.
