These beautiful animals are only a few cells thick and are very simple.  They absorb oxygen through the skin, lack a complex nervous system, and food and waste is exchanged at the mouth.  Despite their delicate bodies flatworms are active carnivores that prey upon small invertebrates.  The majority of species are active at night.  Due to their cryptic nature, multitude of color patterns, and scarcity of flatworm specialists, many remain undescribed.
