It's #WorldOctopusDay 🎉 Known for their alien-like appearance, with eight arms, bulbous heads and large eyes, octopus are the camouflage champions of the seas 🐙 Their amazing ability to hide in plain sight comes from a network of pigment cells and specialised muscles in its skin, allowing it to instantaneously match the colours, patterns and even textures of its surroundings! Considered the most intelligent of all invertebrates, they are found in tropical and temperate waters across the world
