How to draw...

Build one swimming sea turtle from a tilted shell-and-head outline, connect exactly four flippers, and divide the shell into five bold scutes before adding a curious almond eye, spotted skin, bubbles, and water motion. This easy 20-minute marker lesson practices reserved attachment gaps, countable shell structure, expressive profile details, and saturated felt-tip color with visible handmade streaks.

Let's draw a sea turtle

Treat this as one playful practice round: sketch the idea loosely, simplify the shapes, then commit with confident marker outlines and bright fills.

  1. 01
    Shape the shell and head stage for how to draw a cartoon sea turtle swimming

    Shape the shell and head

    Draw one broad domed oval shell tilted slightly upward, leaving exactly four short gaps around its edge for the flippers. From the front opening, connect a curved neck to one small rounded head pointing toward the upper right, notch one tiny open diamond mouth into the face edge, and close the rear with one small pointed tail.

    Marker tip: Keep the shell wide and the head small. Count four empty attachment gaps before closing the tail so each flipper has a clear final position.

  2. 02
    Attach four flippers stage for how to draw a cartoon sea turtle swimming

    Attach four flippers

    At the four reserved shell gaps, attach exactly four separate tapered flippers: two broad front flippers and two shorter rear flippers. Keep every attachment visibly connected and leave the small tail unchanged.

    Marker tip: Work one gap at a time and trace each flipper back into the shell edge. The two front flippers can sweep farther than the two rear ones.

  3. 03
    Add the face and five scutes stage for how to draw a cartoon sea turtle swimming

    Add the face and five scutes

    Place one large almond eye on the visible side of the head with its pupil high and forward, then add one raised curved brow. Keep the tiny diamond mouth unchanged, echo the shell with one inner rim, and draw exactly five large curved scutes that fit together without crossing it.

    Marker tip: Use the high pupil and lifted brow for a curious look. Count five separate shell compartments before moving on.

  4. 04
    Build the turtle texture stage for how to draw a cartoon sea turtle swimming

    Build the turtle texture

    Draw one curved seam inside each of the four flippers and scatter small round spots across the head, neck, and flippers. Keep the eye, mouth, inner rim, five scutes, tail, and every attachment clear.

    Marker tip: Curve each seam with its flipper and vary the spot sizes. Leave open paper between spots so the teal fill will still read clearly.

  5. 05
    Add bubbles and water motion stage for how to draw a cartoon sea turtle swimming

    Add bubbles and water motion

    Draw exactly three round bubbles above the head, exactly two curved aqua water swooshes behind the rear flippers, and reserve exactly two small open-paper highlights inside the established shell. Change no turtle contour.

    Marker tip: Group the bubbles as three different sizes and keep the two swooshes separate. Place one highlight high on the shell and one lower for an easy final count.

    Color the swimming turtle

    Fill the established skin with bright teal, the shell rim with deep navy, the five scutes with coral and golden yellow, and the spots with navy. Deepen the existing aqua bubbles and swooshes, leave both shell highlights open, and add no new contours.

    Marker tip: Pull marker strokes along each flipper and shell compartment. Count four flippers, five scutes, three bubbles, two swooshes, and two highlights, then stop while the texture still looks handmade.
