Marty’s photo of the day #5147: I shot this photo while snorkeling in a tiny lake filled with stingless jellyfish. In the ocean, stings from this species of jellyfish pack a wallop, but in the lake, where they are cut off from predators, they’ve lost their ability to sting. Swimming with them was so much fun! They’d bounce off our masks and each other and simply change directions. Lakes with stingless jellyfish like this are extremely rare.
