Visualize an engaging image showing a group of different vertebrates including a fish, bird, reptile, and mammal. Each animal is highlighted in a unique way: fish showing its scales, bird flapping its wings, a reptile stretching its limbs, and a mammal standing upright displaying its backbone. They are all presented in a bright and lively natural environment. The image purposefully avoids focusing on any single animal's brain. Remember, the image should not contain any text.
