E)elvers.

Accepted Answer

Chaetognaths are commonly known as arrow worms because of their distinctive shape – they have long, slender bodies with arrowhead-shaped heads. The name "chaetognath" comes from Greek and means "bristle-jaws," referring to the rows of bristles or spines along their jaws that they use to capture prey. Acorn worms, spoon worms, and lancelets are all types of marine worms, but they are not closely related to chaetognaths. Elvers are juvenile eels, which are completely unrelated to chaetognaths.
