The visit to the Okinawa aquarium was delightful.
Apart from big tanks with panoramic views of the sharks, sting rays etc, there are also small tanks with the small fishes and corals.
This is a picture showing the small fishes and the colorful corals.
Please enjoy 🙂
The following is extracted from a website known as Marine Science Today which I think is very interesting for reading:
Did you know that jellyfish have been orbiting Earth since the early 90s? To study the effects if weightlessness, NASA launched into space 2,487 jellyfish polyps that eventually became more than 60,000 jellies. The end goal of the experiment was to see how the jellyfish developed without gravity and how they would respond once back on Earth. Jellyfish were used because they, like humans, orient themselves according to gravity. It turns out that the space jellies didn’t develop that gravity-sensing abilities and they had trouble getting around once back in gravity.
I didn’t know that they don’t like gravity.
They are just amazing!
