Facts:

Their colors vary from island to island, and even vary on the same island.

The Happyface was first discovered in 1900 and we really didn't know too much about them until 1972.

They get their name from what "appears" to be a happy smiling face on their bodies (abdomen).

They are usually found beneath the leaves of certain plants.

The Happyface spider is about one-quarter inch long.

They are mainly nocturnal.
