The Spiny Water Flea
Spiny water fleas are an aquatic non-native invasive species. They are tiny zooplankton, usually no more than a centimeter in length. Spiny water fleas have an abnormal body. They have a head with one large black eye and a pair of mandibles for a jaw, four pairs of legs, and a large spine with thorn like barbs. The spiny water fleas' spine or tail is over 70 percent of its total length and is used for its protection.
