All are true regarding trematodes except:
|A||They are hermaphrodites|
|B||Usually there are two intermediate hosts|
|C||Schistosoma hematobium infection is acquired through metacercaria ingestion|
|D||In paragoninum westermani the second intermediate host is the crab|
a. Infection with S. hematobium occurs due to penetration of skin by cercaria.
b. Trematodes are leaf-like, unsegmented flat worms with no body cavity.
c. They have an incomplete alimentary tract starting with oral sucker and have a ventral sucker for attachment
d. Body is covered with tegument often covered with spines. Well developed excretory system with flame cells and collecting tubules leading to a median bladder
e. They are hermaphrodite except Schistosomes and have a highly developed reproductive system
f. All lay eggs which are operculated except schistosomes. Eggs are passed in feces except in S.hematobium and Paragonimus westermani
g. They all have two intermediate hosts except Schistosomes
