Trematoda are parasitic flatworms that range in size from 0.04 to 0.4 inches in length. They have a flattened body with two suckers, one at the front and one at the back. They are found in a variety of aquatic habitats, including freshwater, brackish, and marine environments. Their lifespan is typically between one and three years. The current population of Trematoda is unknown, but they are believed to be widespread.
Name Origin: The name Trematoda is derived from the Greek words trema, meaning "hole," and odon, meaning "tooth." This is in reference to the presence of two suckers on the head of the organism, which resemble teeth.
