Question

You are trying to classify a recently discovered animal. You think it may be an annelid. What would you need to observe to decide that it is indeed an annelid and not another type of worm?

Answer 1

To determine if an animal is an annelid, observe the presence of multiple body segments, metamerism, and specialized structures like chaetae and parapodia.

Step-by-step explanation:

To determine if an animal is indeed an annelid, you would need to observe certain characteristics. Annelids are segmented worms, so one key characteristic to look for is the presence of multiple body segments. Another characteristic is metamerism, which means that internal and external features are repeated in each segment. Additionally, annelids have specialized structures like chaetae and parapodia for locomotion. By observing these characteristics, you can confirm if the animal is an annelid and not another type of worm.
