The Brachycera includes more compact, robust flies with short antennae.
Trematoda is a class within the phylum Platyhelminthes that contains two groups of parasitic flatworms, commonly referred to as flukes. The trematodes or flukes are estimated to include 18,000 to 24,000 species, and are divided into two subclasses.Nearly all trematodes are parasites of mollusks and vertebrates.natomy Trematodes are flattened oval or worm-like animals, usually no more than a few centimetres in length, although species as small as 1 millimetre (0.039 in) and as large as 7 centimetres (0.23 ft) are known.
