Jellyfish make awful pets. Thankfully the resourceful Japanese have come up with a way round that - silicon rubber jellyfish floating around in a gentle stream illuminated by colour changing LEDs. picked by pocksucket 2 years ago

The oldest known fossils of jellyfish have been found in rocks in Utah that are more than 500 million years old. The fossils are an unusual discovery because soft-bodied creatures, such as jellyfish, rarely survive in the fossil record, unlike animals with hard shells or bones. picked by AutumnLotus 2 years ago

Hundreds of years ago the lake had an outlet to the ocean but when the sea level dropped the jellyfish population were isolated in the algae-rich lake and began to thrive. With no risk of being eaten, the jellies multiplied in the lake on the Pacific island of Palau. Over time their stings weakened and visitors can now swim alongside them with no fear of being stung. picked by AutumnLotus 9 months ago
