Under the water and along the shore: a dolphin mid-jump, an octopus with curling arms, a shell collection to trace. Sea creatures are a good fit for coloring because almost nothing has a fixed color — a purple whale is a perfectly correct whale.

Choose a sea animal page for the activity

Start with the smiling dolphin, humpback whale, or pufferfish for broad areas to color. The sea turtle's shell can become a repeating pattern, while the clownfish stripes make an easy color-sequence activity. There is no required palette, so children can invent ocean colors and explain their choices.

Use the dotted starfish or shell page for pencil practice. The octopus has eight arms to count and color, and the jellyfish and seahorse offer more detail for a longer session. Print at full size to keep the smaller outlines clear.
