Jellyfish Coloring Pages

Make free printable jellyfish coloring pages from 12 jellyfish we drew ourselves: a moon jellyfish with four rings in its bell, a lion’s mane jellyfish with a mass of long tentacles, a box jellyfish with a square bell, a comb jelly with its comb rows, a striped sea nettle with long ribbon arms, a jellyfish bloom of seven jellyfish, a deep-sea jellyfish with a frilled skirt, an upside-down jellyfish resting on the sand, a jellyfish with little fish, two jellyfish, a patterned jellyfish for older colorers and an easy jellyfish for little ones. Every jellyfish is our own simple drawing, with no film, book, game or cartoon characters and no brands, so the pages suit homes, classrooms and libraries. Print one big jellyfish on a page, a grid of four or six small ones, an underwater scene with five jellyfish, a fold-in-half card, or a jellyfish mandala with small jellyfish round the edge and a new pattern at the press of a button. Blank jellyfish to decorate prints 1, 2, 4 or 6 plain jellyfish outlines with no pattern on the bell, 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 jellyfish 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.

Jellyfish facts to read while you color

• Jellyfish are mostly water. NOAA’s Ocean Service says only about 5 percent of a jellyfish’s body is solid matter, and that jellyfish have no brain, blood or heart.
• Jellyfish can sting with their tentacles, the same NOAA page says.
• The moon jelly is named for its see-through, moon-like bell. Its young settle on or near the seafloor as polyps, which later release tiny jellies that grow into adults, says the Monterey Bay Aquarium.
• Comb jellies swim by beating eight rows of tiny comblike plates, and the rows break up light into a shimmering rainbow.
• Many deep-sea jellyfish are red. NOAA Ocean Explorer says red is common among deep-sea jellyfish because the color is invisible in the darkness of the deep sea.

Coloring ideas

• Moon jellyfish: a pale, see-through blue or lilac bell with pink or purple rings.
• Deep-sea jellyfish: a deep red skirt on a dark blue or black sea.
• Comb jelly: a clear body with rainbow colors along each comb row.

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.

Frequently asked questions

Are these jellyfish coloring pages free?

Yes. Every page is free to make, download and print, with no sign-up and no watermark. All the jellyfish are our own drawings.

Which jellyfish are there?

12: moon jellyfish, lion’s mane jellyfish, box jellyfish, comb jelly, sea nettle with long arms, jellyfish bloom, deep-sea jellyfish, upside-down jellyfish, jellyfish and little fish, two jellyfish, patterned jellyfish, easy jellyfish. On top of those there is an underwater scene, blank jellyfish, a mandala, a lettering poster and name pages.

Is a jellyfish a fish?

No. NOAA’s Ocean Service says jellyfish are simple invertebrates in the group Cnidaria. They have no brain, blood or heart, and only about 5 percent of a jellyfish’s body is solid matter: the rest is water.

Is a comb jelly a jellyfish?

Not quite. The Monterey Bay Aquarium lists comb jellies in their own group, Ctenophora, while NOAA puts jellyfish in Cnidaria. Comb jellies swim by beating eight rows of tiny comblike plates, and those rows break up light into a shimmering rainbow.

Why is one jellyfish upside down?

That is how the upside-down jellyfish lives. The Monterey Bay Aquarium says it rests its bell on the seafloor and waves its lacy underparts up toward the sun, so the algae living inside it can make food from the light.

Can children design their own jellyfish?

Yes. Choose Blank jellyfish to decorate and pick 1, 2, 4 or 6 per page. Each is a plain jellyfish with an empty bell, two arms and six tentacles. With no title, one fills a 186 mm square on US Letter; six fill 77 mm squares.

Which jellyfish pages suit toddlers and preschoolers?

Choose Simple lines: big shapes with thick outlines. The easy jellyfish and the patterned jellyfish have the fewest shapes, as the table shows.

Can I make a page for every child in my class?

Yes. Choose Class set, pick a picture and paste the names, one per line, up to 40. Each child gets the same picture with their own name in hollow letters at the top, all in one PDF.

Are there jellyfish coloring pages for adults?

Yes. Choose Jellyfish mandala with Detailed lines: each pattern number gives a different symmetric design. Choose 16 repeats for the most intricate pattern.

Can I sell what I make with these pages?

Yes. The pictures are our own drawings, and the note under the tool sets out how you may use them, including for things you sell.

How do I print the coloring pages?

Download the PDF and print it on plain paper. Choose 100% or Actual size to keep the margins and sizes as drawn; Fit to page also works if your printer cuts off the edges.

Is anything uploaded?
