Which animal is not a vertebrate?

Explanation:
Backbones distinguish vertebrates from other animals. Jellyfish are invertebrates because they lack a spinal column, so they do not have a backbone. Whales, goldfish, and falcons all have backbones that protect the spinal cord, classifying them as vertebrates. The presence of a backbone is the main trait that separates vertebrates from invertebrates, which is why jellyfish are not vertebrates.
