Current Question (ID: 13599)

Question:

In which of the following animals, the body is cylindrical and is composed of an anterior proboscis, a collar, and a long trunk?

Options:

1. Hemichordates
2. Urochordates
3. Cephalochordates
4. Vertebrate chordates

Solution:

Hemichordates are marine animals that exhibit a cylindrical body plan consisting of an anterior proboscis, a collar, and a long trunk. The proboscis is used for feeding, while the collar and trunk are involved in locomotion and respiration. Hemichordates are considered to be closely related to echinoderms, such as sea stars and sea urchins, and are part of the deuterostome group of animals. Urochordates, cephalochordates, and vertebrate chordates do not exhibit the cylindrical body plan described in the question.
