Dogfish Anatomy

Squalus acanthias, the Spiny Dogfish, is well known by biology students the world over. Most (if not all) have delved into its internal anatomy in search of knowledge, the meaning of why we’re called “vertebrates”, and/or a good grade.  Here are the cleaned up versions of two of my dogfish anatomy drawings from when I took Vertebrate biology. I hope it helps some of you out there study for that lab exam!

I tried out a few different techniques in these drawings. If you have any suggestions for me to improve my work, or something you liked in particular, please comment!
