It is long, tubular and translucent. What is it???

Diving in Tarifa Spain I've seen these things a couple of times but no one I've asked knows what they are exactly.

If you look at this video at 1:40 BUCEO EN TARIFA16 MARZO 2012 - YouTube

or this one at 2:35 Tarifa Scuba Dive - YouTube

although I'm not even sure that those two are the same things...lol...

A loofah?

sea salp?

Sea Salp looks close but I'm not sure. I should have mentioned that they are about 2-3 feet long and have the diameter of a baseball, give or take a little either way. The only thing that the guys running the dive shop told me was that they are harmless, they don't sting.

That is another pyrosome.

Well done! Now I wanna go to Tarifa

Thanks guys. After looking up pyrosome I found this video Life, Death & Rebirth - YouTube and found a tone more info. It appears that when you shine your light on some of them they "glow" back. I'll have to remember this next time and hopefully I'll have my video camera with me.
