Thank You Lightbeing, that one large blue/purple is a beautiful sight.

And SEAHORSES, Maybe I'll get one for my Granddaughter, tell her I got her a 'pony.'

Thank You Mudra, for that video of those AMAZING deep-sea creatures.

The one sending multi-color signals, how could such ones ever have evolved? Must be either for finding mates or food.

While watching the video, I remember coming across a story about a deep jelly-fish creature (actually, it's a Hydrozoan) which has been found to be virtually immortal: ...

The little critter is known as Turritopsis nutricula

If you’re thinking McLeod, you couldn’t be further from the truth. What you have to do is think small; not microscopic, just big enough to see with your naked eye. Turritopsis nutricula is a hydrozoan, and it’s considered by scientists to be the only animal that cheated death.

Solitary organisms are (according to current belief) doomed to die, after they completed their life cycle. Hydrozoa are a huge class of predatory animals that live mostly in saltwater, closely related to jellyfish and corals. Eggs and sperm from an adult jellyfish (medusa) and they then develop into polyp stage. Medusae evolve asexually from polyps.

Still, our Turritopsis nutricula (could we call it Joe??) managed to find a way to beat that. What these little folks do is they revert completely to a sexually immature, colonial stage after they reach sexual maturity. They’re even cooler than that. When they’re young they’ve got only several tentacles, but at a mature stage, they get to 80-90 of them.

They’re able to return to polyp stage due to a cell change in the external screen (Exumbrella), which allows them to bypass death. As far as scientists have been able to find out, this change renders the hydrozoa virtually immortal.

So, I'm thinking - since these critters are immortal, we should all be knee-deep in them by now. Then something else down there must find them to be quite tasty.

Love and Blessings
