what s that

i filmed this in Turkey

My theories:

• an alien
• an underwater slinky
• a jellyfish

I think the third option is most likely. Very funky!

Come on, somebody! I went through every image I could find of tunicates and none fit. I'm really intrigued - someone must know!

ok i found it out now it is a Rhizophysa eysenhardtii

I'm with coinee, definitely an alien. :-)

This is a siphonophore, a colonial organism with specialized zooids that perform different functions for the colony (e.g. Locomotion, stinging prey etc.). There are some deep water species that get up to 50m long!! Really cool critters and great to see some footage - thanks for sharing!

I ran into one of those several years ago.

I remember the pearl shaped head and the yo'yoing tail.

It was about 3" long and stung the hell on my arm.

yes my friend also stung on the face...

Very nice Video !
