Marine scientists still baffled by lake filled with millions of jellyfish

Palau, my home island! Im so proud my country is getting so much recognition! Please come and visit! This is only one of the beautiful wonders my island has to offer <3

The genuine reaction to the camera man falling into the water was appreciated.

This style of reporting reminds me of Charles Kuralt. My dad was a big fan of his work. Both Dad and Mr. Kuralt are gone now but I'm old enough to identify great reporting. Great job, Lee Cowan!

😂 That was funny that the camera guy fell right in.

I went there and snorkeled with these wonderful jellies, it's pretty amazing, some are so very tiny and cute. They do not sting at all. I think Palau was the most wonderful diving I have ever done in my life. Such a beautiful place. Loved this documentary, you captured the magic perfectly.

Thank you, CBS for a good nature report ❤

I was there in the 90's, one of my favorite memories of Palau!

Never would I swim in water where there are Crocs. That is insane. Literally. I did enjoy the story. Not calling you crazy. I just wouldnt do it.

He said crocodiles and I was out 😆 🤣

Palau was in my "backyard" and I'll always regret not having visited before relocating. One day I'll return home and take a side trip there. One of my besties' family is from Palau and she told me years ago that the jellyfish are evolving and their stingers are slowing coming back because of all the tourists that are coming to the lake. They're redeveloping their defense mechanisms.

Absolutely beautiful! I would definitely add that to my “background list”.

my home my island Palau 🇵🇼 one of the best places to swim.

I would be willing to bet money the reason they disappeared in 2016 was because of excessive heat. 2016 was a ridiculously hot year in the Pacific. It demolished a lot of coral reefs. The jellies likely survived because of their lifecycle. What we think of as a jellyfish is just the adult stage, or medusa. They also have a polyp stage, where they’re attached to the substrate like an anemone but much smaller. Those polyps can enter a phase called strobilation, where they get longer and produce stacks of baby jelly medusae, called ephyra. Each polyp can produce many ephyrae, which will grow into the adult jellies we recognize. If you want to see something cute and weird, look up jellyfish ephyra. They’re like little, living asterisks.

One of bff’s from childhood was from Palau.. I loved and still cherish her stories of Palau 20+ yrs later.. it’s crazy to hear about it here❤

High 5 to the reporter who got this assignment

Palau is about a 2hr flight from Guam. It is serviced by United Airlines which uses Guam as its hub. It is really the only way to get to Palau other than by boat.

Thank you CBS for visiting our beautiful Island of Palau 🇵🇼 We hope you visit again soon! 😊

So cool. But no way with crocodiles nearby!

This was beautiful and fun!! Glad the cameraman/producer got a good dip!!

This place is so beautiful. I would love to go there for real
