#2166 - There is a lake in the country of Palau where jellyfish evolved without stingers after the lake's connection to the sea closed, leaving them isolated from their natural predators. These 'Golden' jellyfish are totally harmless to humans and you can swim with them
I didn't believe this, so I googled it ... it's true... well, kind of. Technically, scientists don't know for sure about lobsters and it's actually only one species of jellyfish that can regenerate its cells indefinitely.
Jellyfish. Such ethereal beauty ... ... you can hardly believe that most of them are killers. Apparently most of the jellyfish without any colour aren't dangerous .. but there are exceptions to that - so perhaps best leave ALL jellyfish alone as you really don't want to take chances.
This crazy photo from the Yomiuri Shimbun shows a diver swimming amongst a swarm of giant jellyfish. These giant sea blobs, known as Echizen kurage (Nomura's jellyfish), inflict heavy damage on Japanese fisheries in the Sea of Japan each year.
