Step-By-Step Images and Instructions
1.

Start by drawing an arrow pointing to the left of your page. At the ends, bring a curved line in at the top and bottom, and then take these across to the right to create the outline of your fish.
2.

Add a tail to the back with a “forked” shape.
3.

Draw a small circle just inside the front…
4.

And add another small circle inside this. Shade this almost completely with the black pen, leaving a small strip of white across the left, and a dot inside the circle.
5.

Add a black line to the left of this…
6.

And then add two wavy lines to the face, one on either side of the eye.
7.

Add a crescent moon shape to the right of the eye…
8.

And then add a heart shape, with the point in the top left, below this.
9.

Add a curved line above this heart shape, and then a jagged line behind this. Follow this with a curved line a short distance behind, another jagged line, and two more curved lines.
10.

Now, add a triangular fin to the top, adding a jagged line to the right.
11.

Add another fin to the bottom…
12.

Add two more fins just in front of this…
13.

And then add a series of short marks inside the tails and fins.
14.

Next, add a series of wavy lines all down the back of the fish, and in the central section of the face.
15.

Use an orange pen for the tail, the ends of the fin, and the front of the face.
16.

Use a black pen for the stripes of the body, and the rest of the fins.
17.

Use a lighter orange pen for the rest of the body…
18.

And shade the eye with a lighter orange pen.
19.

Next, grab a black pen and a ruler, and add a series of straight lines all around the body.
20.

Add labels to the ends of the lines. The top labels should read from left to right – “Mouth”, “Eye”, “Lateral Line”, “Dorsal fin”, “Caudal peduncle”, “caudal fin”. The bottom labels should read, from left to right – “Operculum”, “Gills”, “Pectoral fins”, “Pelvic fins”, and “Anal fin”.
And just like that, you have taken your first steps towards learning more about fish – but there is still plenty to uncover!
