Nice!
Zebrafish are good for experiments because you can test phenotypes with a microscope without killing it.
That’s cute. Now throw it back. Thanks.
I imagine this creature would probably be almost entirely invisible under water and look like just a pair of eyes and a spine.
What if there are bigger fish?
How do critters like this even sustain their bodies? Are their blood and nervous systems transparent too?
Their nervous system isn’t. You can see it in the photo.
Allow us to be more transparent for you.
CW: Visible notochord.
Where the poop chute?
You’re looking at it.
I’m assuming it’s a 2-way digestive tract
No, fish have digestive tracts that go all the way through. Changing that would be way harder than keeping it mostly empty or full of water to make it clear.
Only John Cena is perfectly clear.
I love science memes fossilesque thank you
