How to draw a fish diagram

The fishbone figure is painted as follows:

Material preparation: a piece of paper and a black pen.

Operating steps:

1. First, draw two arcs on the paper. The arc is the body of a fish, and the two sides don't need to be closed. Choose the opening position on one side and draw two closed ellipses to form a fish mouth. Note that this mouth is round and flat.

2. Then draw an arc along the longitudinal direction at a quarter of the whole body near the fish mouth, and draw a round fish eye between the arc and the mouth, thus completing the drawing of the fish head. Pay attention to the fish's eyes, don't leave them blank.

3. Draw the fishtail directly at the open end on the other side. The shape of the tail should be enlarged appropriately, and at the same time, the fish tail should be drawn with curves, giving people a sense of suspension of the fish in the water.

4. The dorsal fin and pectoral fin are also painted with curves, which makes the image of fish more like swimming in water. Use curves and straight lines to describe the dynamics of fish.

5. Finally, complete the connecting parts, and check the proportion of each part and whether the fish tail is symmetrical up and down.

Fish is a kind of aquatic vertebrate with variable temperature. It breathes through gills, swims through the swinging of tail and trunk, and feeds on the upper and lower jaws. It belongs to the vertebrate subfamily of Chordata. Vertebrates are generally divided into fish (53%), birds (18%), reptiles (12%), mammals (9%) and amphibians.
