Draw a Jumping Fish: Arc, Splash, and Fin Placement

Object Drawing Lessons

A jumping fish reads clearly when the body follows a smooth arc, the splash sits at the waterline, and the fins support the leap rather than fight it. This lesson uses a simple convention: the fish body is an oval with a pointed head, the tail attaches at the rear, and fins are drawn as short triangular or rounded flaps. You will plan the arc first, place the fish at three positions, then add splash droplets that trace the takeoff and landing. All measurements are hypothetical examples; measure your own paper and tools before drawing.

Practice materials: Printable downloads are not available for this lesson yet. Use the instructions and four exercises below.

Plan the arc before the fish

Start with a light curved line that rises from the waterline, peaks, and returns. A shallow arc looks like a glide; a tall arc looks like a leap. Choose the arc height first because it controls where the fish body can fit.

Mark three positions on the arc: takeoff, peak, and entry. At takeoff the fish tilts upward, at the peak it is nearly level or slightly nose-down, and at entry it tilts downward. Keep the body oval the same size at all three positions so the motion reads as one fish.

1. Draw a horizontal waterline across the lower third of the page.
2. Draw a light arc from the waterline up to a peak and back down.
3. Mark takeoff, peak, and entry points on the arc.
4. Sketch the same oval body at each point, rotating it to follow the arc direction.

Place fins for motion

Fins should support the leap. The dorsal fin sits on the back and can sweep backward at takeoff, then relax at the peak. The pectoral fin near the head can angle outward like a stabilizer. The tail fin attaches at the rear and points opposite the direction of travel.

Use a simple convention: dorsal fin as a rounded triangle on the upper body, pectoral fin as a small flap near the head, tail as a fan shape. Keep fin sizes consistent across the three positions so the fish does not appear to change species mid-leap.

1. At takeoff, sweep the dorsal fin backward and angle the tail down.
2. At the peak, draw the dorsal fin upright and the pectoral fins slightly out.
3. At entry, sweep the dorsal fin forward and angle the tail up.
4. Check that each fin attaches to the body outline, not floating nearby.

Add splash at the waterline

The splash belongs at the waterline, not on the arc. Draw a small burst of droplets where the fish leaves the water and a second burst where it re-enters. Droplets can be teardrop or oval shapes; keep them small and clustered so they read as spray.

A simple convention is to draw three to five droplets per splash, with the largest near the waterline and smaller ones higher. Avoid covering the fish body with droplets; the splash frames the leap.

1. Draw a short horizontal splash line at takeoff and entry.
2. Add three to five droplets above each splash line.
3. Keep droplets outside the fish body outline.
4. Erase guide lines lightly and darken the final fish, fins, arc, and splash.

Check the whole drawing

Step back and check three things: the arc is smooth, the fish body is the same size at each position, and the splash sits at the waterline. If the arc is jagged, redraw it with one continuous motion. If the fish changes size, compare the oval widths.

Use the rubric below to score your drawing. Valid alternatives include a rounded tail instead of a fan, or a single splash burst instead of two, as long as the arc and waterline remain clear.

1. Trace the arc with your finger to check smoothness.
2. Compare body widths at takeoff, peak, and entry.
3. Confirm splash droplets touch or sit just above the waterline.
4. Score each rubric item from 0 to 2.

Worked example

On a page with a waterline at 6 cm from the bottom, draw a shallow arc peaking at 12 cm above the waterline. Place one fish at the peak with a dorsal fin swept upright, a pectoral fin angled out, and a fan tail pointing down. Add three droplets at takeoff and three at entry.

Four practice exercises

Common mistakes

• Drawing the fish body at different sizes along the arc. Use the same oval template or measure the body width at each position before adding fins.
• Placing the splash on the arc instead of the waterline. Draw the waterline first and keep all splash droplets within a short distance above it.
• Letting fins float away from the body. Attach each fin to the body outline and check the connection point.
• Making the arc jagged or too flat to read as a leap. Redraw the arc as one smooth curve and raise the peak if the leap looks like a glide.

Self-check rubric

• Arc is smooth and clearly rises and returns to the waterline (0-2).
• Fish body is the same size at each drawn position (0-2).
• Fins attach to the body and support the direction of motion (0-2).
• Splash droplets sit at the waterline and do not cover the fish (0-2).
• Final drawing is clear and guide lines are lightly erased (0-2).
