Which category includes squids?

• A. Vertebrate
• B. Invertebrate
• C. Mammal
• D. Bird

Answer: (B)

Squids are invertebrates, which means they do not have a backbone or vertebral column. They belong to the mollusk group as cephalopods, with soft bodies and no rigid skeleton, unlike animals that are vertebrates. Vertebrates include mammals and birds, which do have backbones. So the category that includes squids is invertebrate.
