Blue Buttons are not true jellyfish, but are Chondrophores. These are actually colonies of polyps. Each animal contributes something different to the colony. Some form the central disk, while others form the tentacles. Blue buttons generally measure 1.5 inches across or less, and are generally dark blue or turquoise. Blue buttons, like the Portuguese Man of War, and the By-the-wind-sailor, are not true jellyfish, although they are closely related. They are all in the same phylum (cnidaria).

This is one of the world's only pure blue lizards, and unfortunately it's on the verge of extinction. The Blue Anole (Anolis gorgonae) looks like a little slice of sky as it slinks through the dense forests of Gorgona. The lizard is so reclusive and rare that scientists have a hard time even estimating what the total population of the species may be.
