With the help of Marcio Pereira, father of Oceans Below underwater videographer intern Leila, we think we have identified the mystery jellyfish that Gill shot last week at Chumpon Pinnacle. It was a bit of a shock to the team as is it's definitely not common for these waters, but it seems that Gill, while accompanying her group of open water students, filmed a jimble box jellyfish!

Though common around the waters around Coffs Harbour, NSW, to Albany, Western Australia, it seems at least one has made its way to the waters off of Koh Tao. As odd as it sounds to Koh Tao divers, nobody can deny that in recent years more and more odd creatures are being seen in the waters of the Gulf of Thailand.

I've heard speculation that fishing boats which take on water in distant seas only to offload it closer to home are responsible for untold foreign fish species being displaced. Not sure if that's the case, but there's no doubt that these fish do seem to be turning up in unexpected places.

Though we're not looking to begin a raging debate on the subject similar to that which ensued a few years back when Chumpon's Bull Sharks which were commonly mistaken for grey reef sharks (and incidentally, were at last positively identified by a number of shark experts), we would like to know if anyone out there has come across anymore of these jellyfish. Likewise, if anybody would care to weigh in on whether you think we're correct in our experienced- though unscientific eyes- or just dead wrong, please contact us at This e-mail address is being protected from spambots.

This lost jellyfish was filmed by Gill last week

...and another. See the resemblance?
