I’ve often commented on how different shrimps and prawns look in the water compared to how they look out of water. I think this picture was taken out of water...
...and I think it’s a preserved specimen, not a live one. While I would much rather see a living animal, I have to say that this is an impressive image. I like it as an almost abstract curved shape more than for its biology.
The photo description says this is Nematopalaemon schmitti, which Google tells me is usually called the whitebelly prawn. A quick look at Google Scholar tells me that this is from Brazil.
