Studying deep-sea marine life. The top one is a catfish with an unusual fin, and the bottom is an an amphipod (looks similar to shrimp, but isn't)

These guys life in total darkness, and outstanding pressure.  That little shrimpy guy (who was actually pretty huge) glowed bright yellow around his "head" and "stomach."  Very fascinating.  Reference used.

And also, a quick figure sketch I did at home.
