Abstract

Sea urchins are echinoderms that live in the ocean and can be found in most climates. The support structure that encloses the internal organs in sea urchins is called a test, which is an endoskeleton composed of calcium carbonate and has five-fold radial symmetry. On the shell there are ambulacral plates that have small pores for the tube feet of the sea urchin. The raised bumps along the shell that help with joint movement are called tubercles. The oral and aboral views of the test are shown in the artwork. This piece is composed of individual dots that make up the subject using pen stippling with 0.1 and 0.05 micron pen tip sizes. When constructing this piece, I had to think about the small details that were on the test and decided stippling would be the best representation of the texture of the subject.

I am a senior at the University of North Florida majoring in biology with a concentration in coastal and marine biology. I have been creating art since I was a child, however this was my first time attempting scientific illustration. Taking Scientific Illustration with Dr. Keagy taught me a different perspective on what it means to capture a subject and convey information scientifically through art.
