alleryAn animal lives in your small intestine, has a thread-like body and possesses a pseudocoelom. To which phylum does it belong?
AAschelminthes
BPlatyhelminthes
CAnnelida
DPorifera
Answer & Solution
Correct answer: A. Aschelminthes
1. The clues are: endoparasite of the intestine, thread-like body, pseudocoelom.
2. Thread-like round worms with a pseudocoelom are Aschelminthes.
3. Rule out Platyhelminthes: those are flat and acoelomate, not pseudocoelomate.
4. Annelida is segmented and eucoelomate, so it does not fit.
