A Dolphin Beside a Reef and Heart-Shaped Seashell
The dolphin moves through the water beside a coral reef, with a large seashell shaped like a heart nearby. The reef provides a natural ocean setting, while the shell adds the Valentine’s Day motif. Dolphins, coral, and seashells all belong to marine environments, although a naturally perfect heart-shaped shell would be an unusual find.
Life Around a Coral Reef
Coral reefs provide shelter and feeding areas for many kinds of marine life. Although coral may look like rock or a plant, a reef is built by colonies of tiny animals called coral polyps. Dolphins must rise to the surface to breathe because they are mammals rather than fish.
