I chose a dog what the characteristics are is they can be all different shapes and sizes. Also they different colors they can be black, White, brown, and even a gold. That is jest some of color and some time they mixes they also can hear vary well. They are vertebrate because they have a back bone all dogs are different. They are also mammals just like us.
I also choose a jellyfish there characteristics are they do not have a back done so they are invertebrates also they are a type of fish there body are 90 percent water. The body of a jellyfish is divided into three main parts the umbrella, the oral arms around the mouth and the stinging tentacles. There bodys are radial symmetry.
