Current Question (ID: 13551)

Question:

Which of the following animals exhibit all these characters – bilateral symmetry, triploblastic, segmented and eucoelomate?

Options:

1. Echinoderms
2. Roundworms
3. Molluscs
4. Annelids

Solution:

Annelids, which include organisms such as earthworms and leeches, exhibit all the listed characteristics: bilateral symmetry, triploblastic (having three germ layers), segmented body, and eucoelomate (having a true coelom). Echinoderms (such as sea stars and sea urchins) exhibit radial symmetry, roundworms (nematodes) exhibit bilateral symmetry but are pseudocoelomate, and molluscs (such as snails, clams, and squids) exhibit bilateral symmetry but are not segmented.
