Animal groups
The arthropod group is the largest group. Some are small. About less than 1 cm. Some are huge like the giant king crab. Invertebrates have 0 backbone. Some invertebrates are worms and octopus. They can change into a sqiggle or some other unique shape. Vertebrates have backbones and most are warm-blooded like humans and hawks. Warm-blooded creatures change temperature depending on the food that they eat. Cold-blooded creatures change temperature depending on what the weather is outside. Some cold-blooded animals are snakes, gators, crocodiles, and sharks. Mollusks have very, very soft bodies, so they have a shell to protect them. Mollusks include: snails, conches, and clams.
