In this sea animals coloring page, a whale is gracefully swimming through the ocean, surrounded on all sides by a huge school of hundreds of tiny fish.

We couldn’t compile a list of sea animals coloring sheets without including the great hammerhead shark.

Here’s a familiar face we’re always happy to see! It’s everyone’s favorite cartoon fish, Nemo himself!
This awesome looking clow is the main character from Pixar’s much-adored “Finding Nemo,” and your kid will definitely love coloring him.
Nemo is actually a clownfish – a type of orange clownfish that lives in sea anemones, and we can recognize it by his famous orange coloring and white stripes with black outline.
25. Easy stingray coloring page for kids
Some sea animals look entirely out of this world, and this beautiful stingray is something to marvel at.
Although they look nothing like them, stingrays are related to sharks, and they stand out through their long spine tail, which they also use to defend themselves.
Well, a fun fact about these sea creatures is that their colors reflect the color of the seafloor to camouflage them from predators, so we can use shades like brown and olive green.
