Glad you like the silly sketchies XD When I was at school and even in uni I used to hate drawing/finding diagrams for reports/articles/whatever the hell I needed to be writing at the time. Now I have a hard time just throwing text at the internet.
Now that you mention it, they do look a bit like horns don't they XD
Right? :D I was going to either double major in it or have it as a minor when I was doing my biology degree. Sadly I assumed I was too stupid for organic chemistry (required unit and I didn't know dyscalculia was a thing at the time) and then a busted eardrum and many, many years later a chest infection that to this day seems to be affecting my lungs were the final nails in that particular coffin.
Although having said that neither of the big kids have expressed any interest in actually studying marine biology past what we happen do cover in homeschooling XD
