How are invertebrates different from other cold blooded animals?
Invertebrates do not also develop a notochord. The blood temperature of invertebrates is equal to the temperature of the outside environment. Therefore, invertebrates are called cold-blooded animals .
Why are invertebrates sometimes thought of as primitive?
