What Is the Ocean?

The ocean covers about 71 percent of Earth’s surface. Although people usually name five oceans, the Pacific, the Atlantic, the Indian, the Southern, and the Arctic, they are all part of one connected body of water that wraps around the whole planet.

From Plankton to the Blue Whale

Every ocean food chain starts with plankton, tiny plants and animals that drift near the surface. The blue whale, the largest animal that has ever lived, filters huge amounts of tiny shrimp-like krill through the baleen plates in its mouth instead of chewing. A starfish feeds in an even stranger way: it pushes its own stomach out of its body and digests a clam or mussel while the shell is still closed around it.

Dolphin or Shark? The Fastest Way to Tell

Dolphins and sharks are often mixed up in drawings, but they are built very differently. A dolphin is a mammal. It breathes air through a blowhole, gives birth to live young, and swims with a tail fin that is horizontal, moving up and down. A shark is a fish. It has gill slits, rough skin covered in tiny scales, and a tail fin that stands vertical, moving side to side. Looking at the tail is the quickest way to know which one you are looking at, and it is worth keeping in mind while you color.

Where the Ocean Gets Its Colors

Water looks blue mainly because it absorbs red light faster than blue light, and it often turns green or turquoise near the coast where algae and floating particles catch the light. Far below the surface, red light disappears first, so many deep-sea animals are actually red, even though they look black in that dark water. Coral reefs really are as colorful as they appear, while dolphins and sharks are usually gray with a lighter underside.

How to Print and Color These Pages

Every PDF in this set is formatted for A4 paper, so it also prints cleanly on US letter paper with a small margin. For the sharpest lines, print at actual size or 100 percent rather than “fit to page,” and choose your printer’s standard or best quality setting instead of draft mode, especially for the more detailed sheets. Plain copy paper is fine for crayons and colored pencils; if markers or watercolor are involved, a slightly heavier cardstock will keep the color from bleeding through to the next page.

Match the sheet to the colorist. The simplest pages, with one large fish or a bold, chunky coral shape, suit toddlers and preschoolers who are still learning to stay inside the lines. Pages with more outlines and smaller sections work well for elementary-age kids. The busiest sheets, full of fine coral texture, patterned scales, or mandala-style designs, are best saved for older kids, teens, and adults who enjoy filling in a lot of small spaces.

After Coloring: Craft Ideas

• An ocean wall display. Line finished pages up along a hallway or above a desk for an instant underwater mural, or group them by color: cool blues and greens on one side, warm coral and clownfish colors on the other.
• Handmade cards. Cut a smaller creature, like a starfish or a seahorse, out of a finished page and glue it to folded cardstock for a birthday or thank-you card.
• A bedroom or classroom banner. Punch two holes in the top corners of several pages, thread them onto string or ribbon, and hang the whole ocean scene as a garland.
• A keepsake ocean book. Punch holes along one edge of several finished sheets and tie them together, or slide them into a binder, to build a coloring book a child made themselves.
