Which Schistosoma species has a large terminal spine?

Explanation:
Egg morphology is used to distinguish Schistosoma species. A large spine at the terminal (posterior) end of the egg is characteristic of Schistosoma haematobium, which is associated with urinary schistosomiasis. The other species have different spine patterns: Schistosoma mansoni shows a prominent lateral spine, while Schistosoma japonicum and Schistosoma mekongi have small or inconspicuous spines rather than a large terminal one. So the presence of a large terminal spine specifically identifies Schistosoma haematobium.
