Question

what are vertebrates?​

Answer 1

$\huge{ \underline{ \mathsf{ANSWER: }}}$

• Vertebrates are organisms which have an internal backbone surrounded by bone, also called vertebrae. They have a hard skeleton made of bone, that supports the body's tissue and anchor muscle. Animals that don’t have spines are called invertebrates.

Answer 2

Answer:

A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates include birds, fish, amphibians, reptiles, and mammals.
