Question

Which one of the following annelids is phosphorescent in the dark?
Options
A Aphrodite
B Chaetopterus
Correct Answer
C Syllis
D Sabella
Correct Answer

Option B is the correct answer.

Detailed Explanation

Chaetopterus, commonly known as the parchment tube worm, is a marine polychaete annelid known for its bioluminescence. It produces a blue-green light, particularly when disturbed. This phosphorescence is a form of defense or may serve other functions. Aphrodite (sea mouse) has iridescent setae but is not typically phosphorescent; Syllis and Sabella are not known for phosphorescence.

Hint

This marine polychaete, which lives in a U-shaped parchment tube, is known for its bioluminescent properties.
