Biology Final - Vertebrates

Believe it or not, some creatures out there don’t have to rely on a backbone or a bony skeleton to get them through life as we do, but today we’ll be looking at the animals that do! We and the rest of the organisms out there that use a backbone are called vertebrates, and in the following quiz we’ll be testing your knowledge on them and what sets them apart from invertebrates! Good luck!
