RE: Aquatopia
I'll be an octopus, too, please. Open ocean sounds scary, so I can do both a reef and ocean if need be.

Moray eel.

Looks creepy but generally harmless.

And crooners will sing to me:

What's that fish
In the reef
With the sharp
Shiny teeth?
That's a Moray!

RE: Aquatopia
I think I'd like to be a Jellyfish out in the open ocean - at least part of one. From what little I've read, and I may not even understand it correctly, many Jellyfish are actually made up of different distinct creatures.
Usually, there's a top bit then, a couple different dangly bits then, there's the inside bit. They all seem to work together. I'm on a limited screen right now but I'll try to find some photos and further info to either trash this notion or back it up. But yes - I'd be the Jellyfish. Shy

RE: Aquatopia
Here we go:
"Siphonophores are colonial animals. This means that they are composed of many physiologically integrated zooids. Each zooid is structurally similar to other solitary animals, but the zooids are all attached to each other rather than living independently. They do not come together to form a colony, but arise by budding from the first zooid, which itself develops from a fertilized egg." Pretty cool, huh? Shy
Here's a pretty one...
[Image: siphonophore_zpswcw8axpj.jpg]

"Siphonophores differ from most other colonial animals in two fundamental respects. First, there is a high degree of specialization between the zooids. Zooids specialized for one function usually have well developed features to serve that function but lack the structures associated with other functions. For instance, the nectophores that propel the colony through the water (which are a type of medusa) can’t eat, and the feeding polyps can’t swim. Each is dependant on the other to do what it can’t do. Second, the specialized zooids of a siphonophore are arranged in an extremely precise pattern. This pattern is the same from colony to colony of the same species, but different between species."

That's pretty telling - each individual part has to work together to survive. I kind of dig that. Smile

This is of course, the Portuguese Man o' War ... one colony.

The genus Velella, known as the By-the-Wind sailor, and Porpita, known as blue-buttons (not to be confused with blue-bottles), are two interesting Hydrozoans (Cnidarians) that live at the surface of the water. Instead of living attached to rocks on the bottom, its "substrate" is the ocean's surface. These hydroid colonies bud off tiny medusae, little "jellyfish", just like many benthic hydroids do. The medusae live, feed, and reproduce in surface waters (Larson, 1980).
So, this ...

is a colony of Velella.

And this is what many colonies of Velella look like ...

How about a Tethys Vagina, Kimmie? Tongue





The very lovely Prof. Iain Stewart swam with the golden jellyfish of Palau in an episode of Earth: Power of the Planet (can't remember which one, though). The whole series (and all his other ones) are great! As I might've mention one or twelve times Shy

I have seen a raft of Sailors-by-the wind, very cool.

I’ve swam in that lake, if you go too deep the water is toxic with hydrogen sulfide, otherwise it is a mind-bending experience surrounded by these jellyfish.

RE: Aquatopia
I always thought seahorses were pretty cool.

Apparently, seahorses mate for life, so they find their one true seahorse and float off into the sunset together. I kinda like that since I'm a romantic Tongue

I'd find a pretty reef to live in with the seahorse of my dreams, warm water, living symbiotically with other sea creatures.

RE: Aquatopia
FullCirlce, I read somewhere you're not allowed to scubadive there? Or is it just diving, but swimming is okay? They also nearly disappeared some time ago and are especially vulnerable to climate change Sad

Oh, DLJ, I forgot, they are also the nearest thing you'll get to socialist creatures, they are travelling together and in such a way, that everyone can get enougn sunlight (pretty democratic, too; and tolerant of others, as well. Might have to change my answer... if I wanted to depend for my survival *entirely* on someone eles... which I don't think I am) Yes

"Their success comes down to a remarkable adaptation.Their bodies play host to
thousands of other organisms, photosynthetic algae that harvest energy directly from sunlight. The jellyfish engulf the algae as juveniles, and by adulthood algal cells make up around 10% of their biomass. Grouped into clusters of up to 200 individuals, they live inside the jellyfish's own cells. The Golden Jellyfish uses algae to get most of its energy from photosynthesis. They go to the surface and gently. They're gently turning.The reason they do that is to give all their algae an equal dose of sunlight. So they're quite democratic creatures, just making sure they get as much food as they can."



Jennybee, and these are the cutest of them all <3
