About these under the sea coloring pages

From a smiling starfish in the shallows to a sunken ship on the sea floor, these under the sea coloring pages explore the ocean from top to bottom. The easy level, for ages 3 to 5, keeps things to one sea animal, such as a seahorse or a waving crab. Ages 6 to 8 get coral, sand or a treasure chest around the main subject, ages 9 and up get busy reef, kelp forest and shipwreck scenes, and the expert pages offer an ocean mandala and a detailed seashell frame.

The ocean coloring pages work well for a unit on ocean habitats: color the reef scene and the kelp forest page, then compare the warm water where reefs grow with the cool water kelp needs. Try blending light blue at the top of the water into deep blue near the sea floor.

Also in summer coloring pages.

Under the Sea facts to share

  1. Oceans cover about 71 percent of Earth's surface.
  2. Coral reefs are built by tiny animals called coral polyps.
  3. The deepest known point in the ocean, the Challenger Deep, is nearly 11 kilometers (about 7 miles) deep.

Color idea: Fade the water from pale aqua near the surface to deep navy at the bottom, and give coral bright pinks, oranges and purples for a vivid reef.

Under the Sea coloring page questions

Which under the sea pages work for young children?

The smiling starfish, the seahorse and the waving crab each show one animal with big shapes and almost no background. They suit ages 3 to 5 and also make a fun matching set for an ocean-themed party table.

What animals live in a kelp forest?

Kelp forests grow in cool, shallow coastal waters. They shelter sea otters, sea urchins, sea stars, seals and many kinds of fish. The hard kelp forest page shows otters floating at the surface and fish and urchins among the rocks below.

Why do deep sea animals glow?

Sunlight does not reach the deep ocean, so many animals make their own light, called bioluminescence. They use it to find food, attract mates or confuse predators.
