The parasite utilizes two hosts; the snail and humans; to increase chances of transfer of the
parasite from one place to another;
Have suckers for attachment to host walls; to prevent them from being dislodged;
The parasite produces many larval forms (e.g. miracidia, cercariae and redia) in snails; to
increase chances of transmission and survival; as this feature poses barriers/difficulties in
efforts aimed at eradicating the parasite;
Cercariae larvae and eggs of the parasite have glands that secrete lytic enzymes; which soften
the tissues of humans/snails; to allow for penetration;
Chemical substances produced by the adult worm; protects the parasite from the action of the
hosts; defense mechanisms;
They exist as separate sexes; with the male carrying the female; this ensures that eggs produced
by the female are fertilized before being shed into the blood stream;
