An octopus is one bag and eight questions of where to put things: the head-body is a single soft dome, and every arm is its own S-curve that must taper from shoulder-thick to thread-thin. Vary the eight curls - some reaching, some coiled - or you have drawn a chandelier.
The build is the standard fish one: body oval first, tail second, fins crossing the outline so they attach instead of floating.
ステップバイステップ

ステップ 1
Begin with the body shape.
One long oval, drawn fast. Fish bodies are smooth in a way hands are bad at producing slowly, so go round the shape in one continuous motion and keep the best pass.
気をつけろ A lumpy body built from careful short strokes.
チェック The body should be symmetrical about its long axis.
-
ステップ 2
Draw the tail shape.
The tail is bigger than you think - often a third of the body's length. An undersized tail is the single thing that makes a drawn fish read as a leaf.
気をつけろ A small tail tucked against the body.
チェック The tail should be about a third of the body length.
-
ステップ 3
Draw the gill cover.
One curve, following the round of the head, roughly a fifth of the way along. It separates head from body and does more work than any other single line on the fish.
気をつけろ A straight gill line, which flattens the head.
チェック The gill curve should bow the same way as the nose.
-
ステップ 4
Draw the eye above the middle line.
High and forward - roughly where the gill curve meets the top third. Round, dark centre, one highlight. Too low or too far back and the fish stops looking alert.
気をつけろ Centring the eye in the head.
チェック The eye should sit above the body's midline.
-
ステップ 5
Put the mouth line in.
The mouth sits at the very front, lower than the eye, and it is smaller than instinct says. A short curve is enough - an open grin turns the fish into a cartoon.
気をつけろ A large smiling mouth.
チェック The mouth should be below and forward of the eye.
-
ステップ 6
Add the dorsal fin over the back.
Start the fin lines INSIDE the body so they cross the outline. That overlap is what attaches the fin - drawn outside the line it floats like a flag.
気をつけろ A fin sitting on the outline without crossing it.
チェック Fin lines should visibly cross the body outline.
-
ステップ 7
Add the bottom fin to match.
Compare it to the top fin, not to your idea of a fin: position, rake and size all read against the one you already drew.
気をつけろ A bottom fin that mirrors the top exactly - they rarely match in nature.
チェック The two fins should differ, deliberately.
-
ステップ 8
Add the side fin.
The pectoral fin is the smallest and it sits just behind the gill curve, angled back. It is the one nearest the viewer, so it draws over the body.
気をつけろ Making the side fin as big as the others.
チェック It should be clearly the smallest fin.
-
ステップ 9
Add a hint of the pattern.
Suggest, never itemise. A handful of marks near the head lets the eye tile the rest of the body; drawing every scale turns the fish into a texture swatch.
気をつけろ Covering the whole body in scales.
チェック Most of the body should still be empty.
-
ステップ 10
Draw the octopus markings.
Species markings follow the body's curve and fade toward the belly. Put them on deliberately - they are the difference between a fish and this fish.
気をつけろ Markings drawn flat across a curved body.
チェック Stripes or patches should bend with the form.
-
ステップ 11
Shade so the body reads as a cylinder.
The underside is darker - light comes from above, even underwater in a drawing. One soft band of tone along the belly makes the whole fish read as round.
気をつけろ Even tone everywhere, which flattens the body.
チェック The belly should be clearly darker than the back.
-
ステップ 12
Put the octopus in water - bubbles and a ripple or two.
Three bubbles of different sizes rising off the mouth and two long ripple lines are the entire ocean - more reads as boiling. The bubbles shrink as they rise, and the ripples drift horizontal, which is what places the octopus in water instead of in white space.
気をつけろ A column of same-size bubbles, or ripples that wave like flags.
チェック The bubbles should get smaller as they rise.
-
ステップ 13
Press harder on what stays, remove what does not.
Darken the silhouette and the tail, keep pattern marks light, erase the construction oval. Weight contrast finishes the drawing.
気をつけろ Every line at the same weight.
チェック The outline should dominate when you squint.

これが教えてくれるのは
This is an overlap lesson: every fin attaches by crossing the body outline, and the drawing works exactly to the degree you commit to that.
The octopus teaches the tapering S at volume: eight related but individual curves, each drawn root-to-tip in one or two strokes, each overlapping its neighbours believably. It is a page of line-quality practice disguised as an animal.

必要なもの
A pencil, kept light until the last step, and an eraser you will actually use. The construction is deliberately drawn to be removed.
もし間違ってたら
If the arms look like spaghetti, they do not taper. Each arm starts as wide as your thumb against the body and ends at nothing - the taper IS the arm.
If it reads as a spider, the arms all leave from under the body at once. Stagger the roots around the dome's lower edge, and let two arms disappear behind it.
If it looks lifeless, all eight arms curl the same way. Give every arm a different job: one reaching, one coiling, one trailing - no two matching.

質問
- How do I draw octopus arms so they look natural?
- One S-curve per arm, drawn from the body outward, tapering the whole way, and no two arms doing the same thing. Draw the two front arms fully, let the rest overlap and hide - visible roots for eight arms reads as a diagram.
- Do I need to draw all the suckers?
- Only a run of six or eight along the one or two arms nearest the viewer, shrinking as the arm thins. Suckers everywhere flatten the drawing into a pattern.
- Where do the eyes go on an octopus?
- Low on the dome, at the sides, where the head-bag meets the arms - not up top where a face wants to be. The low-set eye is what makes it look like an octopus instead of a balloon with legs.
- How do I start drawing an octopus?
- One body oval, drawn fast in one motion, then the tail before any detail. Everything else - fins, gill, eye - attaches to that oval by overlapping it, which is what keeps the parts reading as one animal.
- How big should the tail be on an octopus?
- Bigger than feels right - about a third of the body length. An undersized tail is what makes a drawn fish read as a leaf.
- Do I have to draw all the scales on an octopus?
- No, and you should not. A few marks near the head let the eye tile the rest of the body on its own; drawing every scale turns the animal into a texture swatch and loses the big shape you built first.
- Can a beginner draw an octopus?
- Yes - it is one oval, a triangle and some overlapping fins, with a finish-early step marked partway through.
- Why do the fins on my octopus look stuck on?
- They are not crossing the body outline. Start each fin line inside the body so it visibly overlaps the oval - that overlap is the attachment, and it is the single trick this whole family of lessons keeps reusing.
