How do trematodes feed?
Likewise, people ask, how do trematodes reproduce?
Almost all flukes make both eggs and sperm. Blood flukes have separate sexes, and the adult females and males mate with each other. Flukes with a direct life cycle use only sexual reproduction. The entire life cycle occurs in one host, usually a mollusk.
Moreover, what does it mean when all trematodes are parasites?
Trematodes, also called flukes, cause various clinical infections in humans. The parasites are so named because of their conspicuous suckers, the organs of attachment (trematos means "pierced with holes"). All the flukes that cause infections in humans belong to the group of digenetic trematodes.
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) are known. Their most distinctive external feature is the presence of two suckers, one close to the mouth, and the other on the underside of the animal.
