Spot The Difference

As part of my extensive research into the famous dead fish brain scanning study, I decided to read a little bit about the Atlantic salmon (Salmo salar), the fish which started it all.

It turns out, at least according to Wikipedia, that there are various interesting things about this species, for example, it's "much more aggressive than other salmon". Who knew?

However, by far the most interesting thing is that developing salmon embryos are about the cutest things in the world, and look exactly like smiley faces, or maybe Pacman. Those dark spots really are the eyes.

Endless forms most beautiful, indeed.
