difference between nematode and trematode

Most of these animals are parasitic in nature. Trematodes, or flukes, are parasitic flatworms with unique life cycles involving sexual reproduction in mammalian and other vertebrate definitive hosts and asexual reproduction in snail intermediate hosts. Management options would only need to be considered at high levels and when in combination with other nematodes. The worm larvae hatch in intestines, invade the intestinal wall, and then migrate to the lung through the circulation.The Larvae mature in the lung, travel up the bronchial tree, are swallowed, and reach the intestines.
