Fun facts to share while coloring

Fish are vertebrates, which means they have backbones, and most breathe by passing water over their gills to take in oxygen. Their fins help with different jobs: tail fins push them forward, while side fins help them steer and brake. Not all fish look like the classic oval shape; seahorses are fish too, and the males carry the developing eggs in a pouch. Clownfish really do live among sea anemones, protected by a special coating of mucus that keeps the anemone’s stings from hurting them. Many reef fish use stripes, spots, or bright colors to recognize their own species, confuse predators, or blend into coral shadows.

Coloring tips

Fish pages are perfect for an ocean palette: silvery gray bellies, blue-green backs, orange goldfish, lemon-yellow tangs, black-and-white clownfish bands, turquoise water, pink coral, olive seaweed, and dark glossy eyes. For scales, color in curved rows that follow the body instead of straight lines; a slightly darker edge on each scale makes the fish look rounded. Fins often look translucent, so try a light base color with darker strokes along the thin fin rays. Leave a small white shine on the eye and along the top of the body. For a creative twist, turn one fish into a “reef map” by filling its scales with tiny coral shapes, shells, bubbles, and wave patterns.
