“I did my Ph. D on olfaction in sea turtles, sequencing the olfactory receptor genes of the three species featured in my tattoo (leatherback, loggerhead and green). The “bubbles” represent DNA.”–Dr. Michelle Vieyra, University of South Carolina.

Congratulations, Dr. Vierya–your submission is the 100th addition to my Flickr set of science tattoos. Make full use of your bragging rights.
