NEET BIOLOGY

Detailed explanation-1: -Vertebrates are animals that have backbones and an endoskeleton (skeleton inside their bodies). In contrast, invertebrates are animals that do not have backbones.

Detailed explanation-2: -All vertebrates have an endoskeleton. However invertebrates can be divided again between those with an exoskeleton and those with a hydrostatic skeleton. Endoskeletons are lighter than exoskeletons. As the animal grows so does their skeleton.

Detailed explanation-3: -Vertebrates are animals with backbones and skeletal systems. A backbone can also be called a spine, spinal column, or vertebral column. The individual bones that make up a backbone are called vertebrae.

Detailed explanation-4: -Basically, the vertebrate skeleton is internal (an endoskeleton) while the arthropod skeleton is external (an exoskeleton). Here, both kinds will be referred to as skeletons. The vertebrate skeleton is buried under skin and muscle.
