#remind me to download all the jellyfish pictures people have sent me today hahah ghsjdfsjdbg I need to add them to my collection

[donuts4evry1]

these are jellies from the S.E.A aquarium in singapore!! i think they had more jellies actually but i didn't take pictures... the aquarium overall was pretty cool though, they had lots of huge tanks with large fish and sharks.

the last picture is just a screenshot of a video, but they had the moon jellies housed in a tank where they continually rotated through different lighting colors. it was super pretty but i was wondering if the jellies would be bothered by the constantly changing lights??

AHHH THESE ARE LOVELY!! and your camera skills are so much better than mine, haha. I love how crisp and clear they all turned out ^-^!! (Maybe it's also because the lighting in the aquarium is better? Well, regardless, these are gorgeous photos.)

Rating (14/20):

Diversity - 6/10 - The included species seem to be pretty generic all things considered, but at least there's some variety

Presentation - 8/10 - Everything looks neat and clean, and the Rhizostomid jellyfish have some pigmentation on them. Also, I'm a sucker for Jellyfish Raves.

Learning - N/A - Haven't been there in person, can't say for sure how good the information is.

(I'll ramble a bit about jellyfish eyes under the cut!)

You actually bring up a great point! However, you need not worry about these poor jellyfishes' eyes- they should be completely fine.

Moon Jellyfish are part of Class Scyphozoa- which are about in the middle when it comes to "seeing organ" complexity in Sub-class Medusozoa (or the Jellyfish Subclass).

Their primary seeing organs (Ocelli) are contained within "Rhopalia"- which also control orientation (the uh, position kind not the pride kind) through statocysts and also bell pulsation.

Unlike Box Jellyfish, which have true eyes that can perceive different wavelengths of light, ocelli can only perceive brightness.

Moon jellies exhibit vertical migration (basically raise to the surface during the day and to the bottom at night), so perhaps if the brightness of the lights are played with too much, it might confuse their natural sense of migration? But jellyfish do not have a brain, so I think they will be fine regardless :)

However, since we are on the topic of rhopalia, did you know that moon jellyfish polyps were sent to space in mission STS-40? There's a video on youtube about that with the ugliest looking jellyfish I've ever seen (affectionate). Apparently, they developed just fine in space, though their statocysts seemed to develop improperly. Poor little guys.
