Baby Zebrafish Eyes Work Kind of like Real-Time Photoshop

It will go extinct before we find more about it, though. Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours.

Zebrafish are also hands down one of the best starter aquarium fish. Very tolerant to shifts in water conditions and always active.

This made me happy. First, it was all about fish, which is a rare and pleasant surprise. Second, you mentioned the baby whale fish research possibly helping with a disorder my mom has, though hers is injury-induced, not hereditary.

[@jerrymcfletcher3672]

At "Current Biology" we run different currents through organisms and then record the results, 150 mA's are fun and all but try 10,000...

[@theoverseer393]

Have you guys ever used that greyscale/monochromacy setting turned on for a while? Once you turn it off, things look more vibrant. Try doing this in a dark room, just doing something basic for a while. Then when a good amount of time passed by, like about 5 or more minutes, turn the monochromacy off, and look at something with a lot of color, or basically any of the stuff you already saw in greyscale. I guess my point is this could probably help us to sort of see like an animal with more cone cells

[@MEUProductions]

My University has a huge zebrafish lab lol. They have the local school kids raise their own fish when they learn reproduction in like 7th grade.

Can you make a video on tetrachromacy

[@jasondashney]

1:08 . You just answered a question I've wondered for ages. I've wondered why dim light is never just a less bright version of the vibrant colours we see. It's always muted and dull. Interesting.

[@massimookissed1023]

Try looking at faint stars. Sometimes you can see them better if you don't look precisely at them, utilizing part of the retina with more B&W rods.

[@CompBioQuest]

awesome!!!!! love it!!!, current biology is publishing very interesting papers

[@tedphillips2501]

Isn't the drawing of where the cones/rods in their eye upside down ? Last I looked, their eyes have a focusing lens.

I think you would have to pump against the osmotic gradient, so you would need pumps! not channels! and channels can be non selective.

pretty evenly distributed except for the fovea isn't really accurate there for humans. It's mroe like a gradient towards the fovea and then another pretty harsh increas in cones

[@AssassinGrudge]

it would be amazimg if we have a synthetic image rendered according to how the zbra fish ratina map the world i mean does zbra fish brain process 3 type of signals at the same time it is very complicated for a fish taking in account that also the fieled of view for sea creatures is 180 per eye

[@brianlash6904]

Do fish feel or sence anything when humans are swimming in the water? Because our potassium channels aren't adapted to any intelligible means of communication. Given the depth in water to meet an electric fish, our heart and lungs ions probably would not diffuse into the water. I imagine either sodium or potassium diffusion could have sometime, (or at least for humors sake) accidentally caused a fish to start a really bad rumor of humans. *intelligent fish* (Speaking in potassium ion diffusion among, let's say, catfish) "Wow those creatures communicate badly, and they're loud, what is the loud for?"
