A drawing of Earth Listener in one of zir’s three forms (blue glaucus, frilled shark, and dire wolf).

This is a drawing of a blue glaucus (Latin name is Glaucus atlanticus, but the species’ other common names blue sea slug and blue ocean slug). They are a kind of nudibranch and they usually only a few centimeters long and not much larger then that (Once saw one report saying the record size was 40 cm but not too sure how valid that is.)

Done in color pencil.
