Species of the monogenean worm group Aspidogastrea, which are characterized by a large ventrocaudal sucker (Fig. 1 A in Aspidogastrea.), which is also called Baer’s disc. It stretches at the end of the individual development starting from the terminal end over the whole ventral side. The eggs are excreted into water, where the ciliated, 0.1–0.2 mm long larvae (see Fig. 1 C in Aspidogastrea) hatch and swim around as so-called Cotylocidium larvae. The larvae of A. conchicola enter mussels as well (families Unionidae, Mutelidae, Sphaeriidae, Corbicilidae) but also prosobranchial snails. These larvae become mature in its first host (Fig. 1) and develop inside the organs of both sexes. Other species need obligatorily a second host (e.g., Lobatostoma manteri), parasitize first in snails and finally reach maturity in snail feeding fish (genus Trachinolus). Also turtles may become involved as second hosts. It is also known that larvae of the Aspidobothrea may live in the intestine of...
