A quick sketch of Charles.
some of my favorite invertebrates are illustrated here, including the one I failed to get right on an exam last year (the brachiopod…dammit).
I really should focus on water chemistry but cephalopods just keep swimming in my head!
Squids may look rather phallic but not even close compared to a geoduck… I’ll let you look that one up (may be questionably safe for work).
Fun fact: Cephalopods first appear in the fossil record in the Late Cambrian!
