Use the 0.2 ink liner for the left one and the 0.1 liner for the right one.

The sketch is ready for inking! 3. How to Draw With Ink Liners Step 1īefore we begin inking our octopus drawing, let’s try some warm-up exercises and practice making dots on the paper.ĭotwork (also known as stippling) is a great artistic technique it’s a perfect choice for creating beautiful textures.ĭraw a sample of dotwork that consists of two parts. It's important to make sure that all unnecessary pencil lines are removed before proceeding to any additional artistic tool. Step 9Īs a final addition to this pencil sketch, I draw the suckers. I applied light pencil hatching to the inner parts of the limbs just for your reference. Use your imagination and artistic flair to find the best direction for these arms it’s important to keep the balance of the figure. I draw the second arm from the third pair it is hidden behind one of the arms in the foreground.

Then I add the inner surface and the suckers, just as we did in the previous examples. I draw the remaining tentacle of the third pair. I add the suckers to the second pair of arms. I draw the second pair of arms and then add the inner sides. The suckers get smaller towards the end of the limb, so just mark the smallest ones without adding many details. I add the suckers to the first pair of the arms. Depending on the species, the suckers can be placed in a parallel or a staggered order. For example, if we have an overhead view of a sucker, we’ll see only the top plane with the cavity and no sides.Įach arm has two rows of suckers. The principles of perspective are applicable here, too: the point of view defines how we see the object. The stylized form of a sucker resembles a bowl with a hollow central cavity. I add the inner parts of the first pair of arms. We’ll dwell upon drawing the suckers (the round elements that cover the interior surfaces of the arms) just in the next step. The foreshortening defines how much of the interior surface we see the image below illustrates this concept. To draw the inner parts of the tentacles correctly, we need to keep in mind the principles of perspective. I draw the first pair of arms, keeping the lines smooth and soft. But since it is a common appellation, I'll be using 'tentacles' now and then throughout the tutorial. It's worth mentioning that, according to Wikipedia, the correct name for the limbs of an octopus is 'arms', not 'tentacles'. This topic needs additional explanations, so I'll see you in the next section! 2. How to Draw Tentacles Step 1

Now we are ready to proceed to drawing the tentacles, or the arms. An octopus uses a siphon for respiration and locomotion. I draw the fold of the aperture at the side of the head. They are large, enclosed in a capsule, and have a slit-shaped pupil. Now I mark only the arms that are visible in the foreground, just to keep the process as simple as possible. An octopus has eight arms that can be divided into four pairs. Then I add an oblong shape where the eyes are located.Īccording to this foreshortening, one side of the octopus is more visible to the viewer than another. I draw a slightly curved core line it will help us to mark the positioning of the figure.

How to Draw an Octopus With a Graphite Pencil Step 1

A graphite pencil (I recommend using an HB type)ġ.

We'll also learn to use dots and mix artistic techniques to our advantage! What You Will Need I’ll show you an easy way to create a pencil sketch from scratch, and then we’ll explore the step-by-step process of drawing with ink liners. “You see very weird or very interesting phenomena, and then you say, ‘Oh, nobody looked at this before.The theme of this tutorial is drawing an octopus we’ll base it on the anatomy of this mollusc but also bring some stylization into our artwork. “But it’s always like this in the octopus,” Dr. Uncovering how exactly an octopus arm avoids the light is the next step in understanding this unexpected behavior.

Stranger still, the reflex also seemed dependent on something in the arm’s muscle - when only the skin was cut, the reflex persisted, but not when the muscle underneath was also severed. Though the behavioral response did not require sight, it still required the brain to be intact. The arm stopped retracting from the light when it was separated from the body or when the octopus was anesthetized. Surgical experiments, conducted under anesthesia and with care to minimize suffering, did provide some clues. There is evidence that there are light-sensitive receptors in the skin, but no direct proof yet that they are responsible for the behavior, Mr. However, it is still a mystery how an octopus’s arms can detect light, let alone respond to it.

“We speculate this reflex is for protecting the arms and keeping them folded so that no crabs or fish will bite it when they think it’s kind of a worm,” Dr.
