Which organisms are included in the cephalopod family?

• A. Starfish and sea urchins
• B. Sharks and dolphins
• C. Octopuses, squids, and cuttlefish
• D. Crabs and lobsters

Answer: (C)

The cephalopod family consists of a group of marine animals known for their distinct characteristics, such as their ability to change color, highly developed nervous systems, and advanced motor skills. The correct answer identifies octopuses, squids, and cuttlefish as members of the cephalopod class. Octopuses are recognized for their soft bodies and eight arms equipped with suckers, which they use for grasping and manipulating objects. Squids have a more elongated body and are known for their speed and agility in the water. Cuttlefish possess a unique internal shell called the cuttlebone, which aids in buoyancy, and like octopuses and squids, they also have the ability to change their skin color and texture for communication and camouflage. In contrast, the other options contain groups that are not classified as cephalopods. Starfish and sea urchins belong to the echinoderm phylum, while sharks and dolphins are part of the fish and mammal classes, respectively. Crabs and lobsters are classified as crustaceans, a different group altogether. Each of these categories highlights the diversity of marine life, but only octopuses, squids, and cuttlefish fit within the
