GREEN NUDIBRANCH / TRIDACHIA CRISPATA

This species is called the lettuce slug because it is often green in color, and it always has a very frilly edge to its parapodia. This makes the slug resemble the curly kinds of lettuce, such as the lollo rosso variety. The maximum length of this species is about 5 cm and 3 cm in width. The lettuce slug is extremely variable in color: it can also be blue, or very pale with red lines or yellow lines.
