Moon jellyfish Aurelia aurita These jellyfish can get up to more than a foot in diameter but most on Jetty Island are about the size of a soda bottle bottom and they look a bit like that too. Their threadlike tentacles fire away at prey like miniature harpoons when something touches them. They rarely sting people and, if they do, their sting isn’t serious. Spot along the beaches and floating off shore. (Annie Mulligan / For The Herald)
