How to draw a turtle

Six frames, one sea turtle swimming in profile. The head and one flipper first, then the shell, the rear flippers and the plates.

The animal on this sheet is a sea turtle, not a tortoise, and the distinction is worth making because it changes every limb on the page. A tortoise walks on stumpy pillars; a sea turtle flies through water on long flattened flippers, and those flippers are most of what makes this drawing interesting.

Frame one is the head and one front flipper, drawn as two separate shapes with nothing between them. The shell — the biggest thing on the finished animal — does not appear until the third frame. That is worth reading before you copy, because it means the first thing you commit to is the ANGLE the turtle is swimming at, set by where the head sits relative to that flipper.

When the shell does arrive, draw it as a broad rounded dome, wider than it is tall, with its highest point slightly forward of centre. A shell drawn as a perfect half-circle looks like a bowl; the forward hump is what makes it look like it belongs to an animal that swims. The neck joining it to the head stays short — sea turtles cannot retract their heads the way land tortoises can, so there is no fold of loose skin to suggest, just a smooth join.

The head itself is a rounded wedge with a blunt snout, one visible eye with a filled pupil high on the side, and a gentle curved mouth. Because the animal is in profile you draw one eye and only one, which is worth stating because the instinct to add a second is strong and it always looks wrong.

The front flippers are the shapes that carry the drawing. They are long, flat and paddle-like, much longer than the back pair, and they sweep back and downwards from just behind the head. Draw them with a slight curve along their length rather than as straight blades — a flipper mid-stroke bends, and a straight one looks like a plank glued on.

The rear flippers are shorter, wider and blunter, set at the back of the shell. They act as rudders rather than engines, and drawing them noticeably smaller than the front pair is what tells a viewer which way the animal is going.

The shell plates arrive in the later frames, and they follow a pattern worth knowing: a row of large plates down the centre of the shell, flanked by rows of smaller ones towards the edges, with a border of small plates all the way round the rim. Drawing them as an even grid is the mistake to avoid, because it makes the shell look tiled rather than grown.

Let the plates get smaller and more squashed as they approach the shell's edge. That gradual compression is what makes a flat pattern sit on a curved surface, and it is exactly the same trick that makes stripes work on a fish or patches work on a giraffe.

The last frame adds the belly plate — a separately outlined band along the lower edge of the shell — and the short tail behind the rear flippers. The belly plate is what stops the shell reading as a shield floating in front of the animal, and it takes one line.

The six frames are ordered from the largest closed shape to the smallest, which here means head and front flipper, then the underside, then the shell with its first plates, then the rear flippers, then the remaining plates, then the eye. It is an easy order to copy, and it is not a claim that this is how anyone ought to draw a turtle. Most people would put the shell down first and hang the rest off it, and that is a perfectly good way to work.
