Introduction: The word Chaetognatha is derived from the Greek word chaite, long flowing hair, + gnathos, jaws. It depicts the sickle-shaped bristles on each side of their mouth. Chaetognaths are also called as arrow worms. They are marine planktonic predators.

Expert Solution & Answer

Explanation of Solution

Arrow worms consist of a head, trunk and postanal tail. Their head consists of a large depression called a vestibule which leads to the mouth. This vestibule comprises teeth and edged on each side by curved chitinous spines. The teeth and spines are generally covered by a hood formed from a fold in a neck. A chaetognath in the presence of prey retracts it hood and captures the prey by spreading teeth and spines apart. Once the prey is captured a chaetognath shuts the teeth-spines assembly with tremendous speed. Arrow worms mostly feed on crustaceans, small fish and other chaetognaths.
