Marine Animal Facts and Coloring Pages
The oceans cover just over 70% of the Earth's surface and contain all kinds of unique and amazing animals. Whenever I go scuba diving or snorkeling, I never cease to be amazed at the variety of animals and how different they are from the land animals we've grown used to.
On this page you'll find dozens of ocean coloring pages. I have started with marine creatures - dolphins, fish, jellyfish, stingrays, mantarays, sharks, sea urchins, crabs, starfish, pelicans, and more. I have also included some underwater scenes at the bottom of this page.
You will also be able to learn some interesting facts about different sea creatures here too - some you may have never heard before.
Enjoy your swim!

My sea otter lineart - click to enlarge
Sea otters are one of the smallest marine mammals. They keep warm in the water with their thick coats of fur, unlike most other ocean mammals which have a thick layer of blubber keeping them warm.

Seals only come ashore when they have babies. Otherwise they spend most of their lives in the water. They are well designed for life in the water, with flippers for swimming and a layer of blubber to keep them warm.

Rays - Manta Rays and Sting Rays
My stingray lineart - click picture to enlarge
Rays have flat bodies and pectoral fins which look like wings. This enables them to lie almost unnoticed on the ocean floor. Their mouth and gill slits are on the underside of their heads. Most live along the coasts, but some will swim further out to sea. This group includes sting rays, manta rays, electric rays, and eagle rays.
My own seahorse lineart - click to enlarge
Seahorses are a type of fish with that characteristic horse-shaped head. They swim upright, propelled by their tiny fins. They like to anchor themselves with their tail to sea grass or seaweed. Interestingly, it is the dad who carries the eggs in a pouch after the female lays them.

My turtle lineart - click to enlarge
Turtles have a hard shell to protect their soft body parts. They don't have any teeth, but rely on their sharp jaws to cut their food. Turtles eat seaweed, jellyfish, sea urchins, mollusks, and other invertebrates. All sea turtles lay their eggs on land. After laying her eggs, the female goes back to the sea, leaving the hatchling turtles to make their own way to the sea after they hatch.
My pelican lineart - click to enlarge
Pelicans are strong swimmers with webbed feet. They eat fish which they swallow head first. Many pelicans hunt cooperatively by making a line and herding fish into shallow water.
My penguin line art - click to enlarge
Penguins are flightless birds which spend most of their lives in the water. They have stream-lined bodies with water repelling feathers. They are most common in colder regions.

Goose and acorn barnacle lineart - click to enlarge
Barnacles are usually attached to something, like a whale, a ship, a rock, or pier. Usually we only see the hard shell on the outside of the creature. But hidden inside is a crustacean, or crab-like animal. When the barnacle is covered with water, it sticks its feathery legs out the top to catch any plankton or debris floating by.
Coral and Coral Reefs
Coral lineart - click to enlarge
Corals are small animals, much like sea anemones, which build a protective wall round themselves. The stony coral that we find on the seashore is actually the skeletons of a colony of hundreds or even thousands of these creatures.

My crab lineart - click to enlarge
A crab has ten legs. A crab's legs bend from side to side rather than from front to back. This means that crabs run sideways rather than forwards. There are two types of crabs - land crabs which breathe air, and marine crabs which use gills to breathe underwater.
Hermit crabs don't have exoskeletons like other crustaceans. So they will find an abandoned shell to fit snugly over their soft body. As the hermit crab grows, it will need to look for a bigger shell. It uses its four back legs to anchor itself into its new home.
My jellyfish line art - click to enlarge
Jellyfish are creatures which tend to be carried anywhere the sea currents take them. They can be as small as your fingertip or as big as a huge patio umbrella. The lion's mane jellyfish has tentacles which can be over 100 feet long!
Lobsters are crustaceans which often hide in caves, in crevices, or under rocks during the day. At night they come out looking for food. They are omnivores, eating plants and animals. They have teeth - but not in their mouths. Their teeth are in their stomach!
Octopuses - not octopi!
My octopus lineart. Click to enlarge.
Octopuses prefer to live on the sea floor. During the day, most will hide in crevices and under plants, only emerging when it is dark to find food. They have a very squishy body, able to squeeze into a very small slit. The blue-ringed octopus is a small, extremely poisonous octopus which lives off the coast of Australia. It has enough poison to kill ten people!
Picture credit: my own pic
The sand dollars that you find on the beach are not usually alive. A living sand dollar is like a flattened sea urchin and covered with tiny hairs which are much shorter and softer than sea urchins'. The flower pattern that you see on a sand dollar's test (shell) is where its tube feet stick out. These feet are not used for walking, but for breathing. It actually uses its spines for moving around.
My own sea anemone picture. Click to see bigger.
Sea anemones are actually animals, even though they looks like plants. They come in a bright range of colors (purples, reds, yellows, pinks, oranges, and blues) and even different patterns, such as spotted or striped. They are carnivorous - eating other animals. Their tentacles contain stinging cells which kill or paralyze small fish an other creatures passing too close.
Sea Shells / Snails
Sea urchin lineart. Click to enlarge.
Sea urchins look like pin cushions with spines sticking out. These spines may be long and sharp (usually in tropical waters) or shorter and not as sharp (in cooler waters). It feeds on algae which it scrapes off rocks with it teeth. Some sea urchins can bore holes into rocks with their teeth to make a place to hide.
Squid lineart. Click to see bigger
A squid has ten arms with two of them longer than the others. These are the feeding arms which are used to grab prey. They bring it to the other eight arms which hold the prey while the squid eats. The squid can move super fast by jet propulsion when threatened or release some ink into the water to confuse the predator.
Starfish - sea stars
Starfish picture - click to enlarge
Starfish or sea stars are not really fish at all. They are really echinoderms. Most starfish usually have five arms with their mouth on the underside of their body. A starfish has a very interesting way of eating. Its stomach comes out through its mouth and starts digesting the prey outside of its body. Once the food gets mushy enough, the starfish pulls its stomach back inside its body to finish digesting its meal.
