About these animal coloring pages for adults

The animals for adults all live in the sea. Sea turtles are the largest group, gliding over coral clusters, through a kelp forest, beside a lacy sea fan and under a rock arch, with shells split into plates and flippers covered in small scales. Sharks come in four kinds: a great white showing rows of teeth, a spotted whale shark, a smooth reef shark and a hammerhead seen head-on. Humpback whales dive under a swell, curl through a round wave and swim with a calf. The fish include an angelfish, a clownfish in its anemone, a lionfish with ringed spines, a seahorse with a coiled tail and striped tropical fish. The medium designs leave open water around the animal and keep the reef low, which suits markers or a shorter sitting. The detailed ones fill nearly every corner with coral heads, shells, starfish and bubbles, so plan on several sessions with fine-tipped pencils or gel pens.

Coloring tips

  • Color the water last and keep it light; a pale blue that deepens toward the bottom of the page makes the reef look deeper.
  • A clownfish is orange with three white bands edged in thin black lines, and a lionfish has maroon and white stripes on its spines.
  • Great whites are gray on top and white underneath; follow that line along the body to give the shark its real countershading.
  • On the detailed reefs, work one coral head at a time from the top down so your hand does not smudge finished areas.
  • Sea turtle shells look richer when each plate gets a darker edge and a lighter center, like the amber pattern on a real hawksbill.

Let the water frame the animal

Look for

The medium whale page concentrates curved lines around the outside of its body, while the turtle page gathers most reef detail below the animal. Neither requires a dark full-page background.

Try this

Keep the broad open water pale. Add your strongest water tone only near a few wave edges or behind one flipper, then step back and check that the animal’s silhouette remains distinct.

What you will find

Sea turtles

From an open-water turtle chasing bubbles to one packed into a coral garden, so you can choose how busy the page gets.

  • A sea turtle swims upward toward bubbles above sea grass growing from a rounded rock.
  • A sea turtle moves over a sandy seabed with shells, sea grass and a small coral branch.
  • A sea turtle faces forward in front of a rounded coral-covered reef arch with small fish.
  • A sea turtle glides through a rounded garden of coral, sea plants and small fish.
  • A sea turtle swims beside a large sea fan rooted in a small mound of coral and sea plants.

Sharks

Four shark species with their real shapes, from the hammerhead's wide head to the whale shark's flat snout.

  • A great white shark swims above a crowded coral reef with small fish and sea plants.
  • A spotted whale shark swims above a coral reef with small fish and sea fans.
  • A reef shark glides above a compact coral mound with small fish and bubbles.
  • A hammerhead shark turns above shells, sea grass and a small sandy seabed.

Humpback whales

Long throat grooves and knobby flippers on big diagonal bodies, with swirling water to shade around them.

  • A humpback whale curves beneath a complete oval ocean swell above shells, kelp and coral.
  • A larger whale and its calf swim together above coral, shells, sea plants and small fish.
  • A humpback whale curves inside a complete circular swell of water with bubbles.
  • A young whale swims above a small reef garden with coral, shells and sea plants.

Reef fish

Fins, bands and spines that invite bold tropical color against dense coral.

  • A large angelfish swims among branching coral, sea plants, anemones and shells.
  • Two patterned tropical fish swim on opposite sides of a detailed coral outcrop.
  • A lionfish spreads its striped fins above coral, sea grass and shells on the seabed.

Green sea turtles have olive or brown shells, and the name comes from the greenish fat under the shell. Hawksbills have amber shells with dark streaks, and loggerheads are reddish brown.
