My favorite animal is a dolphin. Dolphins live in the ocean, and they are very playful creatures. They have smooth skin and shiny, gray bodies. Dolphins eat fish and squid, and they can swim very fast! I like dolphins because they are smart and friendly. Once, I saw dolphins at the aquarium, and they did tricks like jumping out of the water. It was amazing! People often think they are fush, but they are mammals and have lungs. They breathe through a whole on top of their body.
