🌊🐙 Have you seen an octopus swimming?

Check out this incredible creature we found on the reef! Did you know that octopuses use jet propulsion to move through the water? 💨 They can even swim backward by pushing water out in reverse! 🌀

With no bones, they can squeeze into the tightest spaces and swim effortlessly! 🦑✨ And when they do swim, they’re masters of stealth, changing colour and texture to blend in with their surroundings. 🎨👀

Such an amazing creature to spot on the reef!
