Octopus Coloring Pages

Make free printable octopus coloring pages from 12 octopuses we drew ourselves: an octopus with curled arms, an octopus sitting in a shell, an octopus on the reef, a blue-ringed octopus, three little octopuses, an octopus mother with her strings of eggs, a swimming octopus, an octopus and its ink cloud, an octopus peeking out of its den, an octopus over the sea bed, a patterned octopus for older colorers and an easy octopus for little ones. Every octopus is our own simple drawing of a real animal, with no film, book, game or cartoon characters, no faces and no brands, so the pages suit homes, classrooms and libraries. Print one big octopus on a page, a grid of four or six small ones, a reef scene with two octopuses, a fold-in-half card, or an octopus mandala with small octopuses round the edge and a new pattern at the press of a button. Blank octopuses to decorate prints 1, 2, 4 or 6 plain octopus outlines with no suckers or spots, so children can design their own; one fills a 186 mm square on US Letter. Type a child’s name for a name page, or paste a class list to get the same octopus for everyone with each name at the top. Choose simple, medium or detailed lines, never thinner than 0.5 mm. Download one multi-page PDF for US Letter or A4, a 300 DPI PNG of every page, or an SVG. No sign-up, no watermark.

Octopus facts to read while you color

• Octopuses are cephalopods, like squid and cuttlefish, with bulbous heads, large eyes and eight arms, says National Geographic.
• Their arms are lined with hundreds of suckers, each of which can move on its own; a female giant Pacific octopus has 2,240 suction cups, says the Monterey Bay Aquarium.
• An octopus can match the colors and even the textures around it to hide in plain sight, and it can release a cloud of black ink.
• If it loses an arm to an attacker, an octopus can regrow one later.
• The blue-ringed octopus is small, and its bright rings warn that it is highly venomous.
• A giant Pacific octopus has a body up to 2 feet (60 cm) long and an arm span of at least 7 feet (2 m), often more than 13 feet (4 m), and a parrotlike beak.

Coloring ideas

• Octopuses change color to blend in, so any color works: red, orange, purple, pink or brown, with the suckers a lighter shade.
• Blue-ringed octopus: a yellow or tan body with bright blue rings.
• Reef: pink, orange and purple coral, green seagrass and light blue water, with white left for the bubbles.

Printing tips

• Every page keeps a 12.7 mm (half inch) margin from the paper edge, on US Letter and A4.
• Plain paper is fine for crayons and pencils; use thicker paper or card for markers or paint.
• Print one page first and check it before printing a whole pack or class set.
• Choose Detailed lines only with fine pens or sharp pencils, and Simple lines with chunky crayons.
