A) as chitin-reinforced bristles for movement only
B) as chitin-hardened tentacles to move sand only
C) as chitin-hardened jaws to capture prey only
D) as chitin-hardened jaws to capture prey and chitin-hardened tentacles to move sand
E) as chitin-reinforced bristles for movement and chitin-hardened jaws to capture prey
Chitin-Hardened Jaws
Structural feature referring to jaws strengthened by chitin, a fibrous substance forming the exoskeleton of arthropods and other organisms.
Marine Polychaetes
A diverse class of annelid worms, commonly known as bristle worms, that live in various marine environments.
Chitin-Reinforced Bristles
Stiff bristles made stronger with the natural polymer chitin, commonly found in the exoskeletons of arthropods.
