I found this article (while researching cod liver oil & ratfish oil) about a fossil that finally helped scientists understand how to put together an ancient fish's mouth. There's such cool stuff out there, and are/used to be so many strange creatures all over our Earth.
This guy is amazing. Check it out. Above is an image from his site. It's such awesome and inspiring art, with really fun twists and plenty of science thrown in.
one last thought to end this post. Have you ever seen a picture of a
salmon? It's long been among my favorite foods, but sometimes we
end-users can be quite detached from our food sources. I'm hoping to
improve that one step at a time in my family's lives. (future LINK)
