While pools are typically restricted to humans only, the ocean is home to nearly 250,000 species of animals, with scientists estimating there could be a million – or more – yet to be discovered. It pays to remember you are sharing with the ocean with others, and while it’s usually not a reason to stay out of the water (unless you’re in Far North Queensland in stinger season or at a beach frequented by saltwater crocodiles), it’s prudent not to pick up a blue ringed octopus, attempt to pat a seal, or remain in the water if you see the Westpac chopper signalling a shark sighting!
