Remora Drawing: Sucker Disc and Fin Placement

Object Drawing Lessons

This lesson teaches a reliable layout for a remora drawing. You will place the sucker disc on the underside of the head, position the dorsal and anal fins toward the rear, and set the pectoral fins just behind the head. The convention is simple: the body is a tapered oval, the head is the front third, and the sucker disc is a flattened oval running along the head's underside from just behind the mouth to about the gill line. Letter styles and line weights may vary; the rubric rewards correct relative placement, not a single perfect outline. All measurements below are hypothetical examples for practice, not manufacturing standards. Use a ruler on your own paper to check proportions.

Body Layout and Head Zone

Begin with a tapered oval: the body is widest just behind the head and narrows toward the tail. Mark the head as the front third of the body length. The mouth sits at the very front, slightly below the midline. The eye is above and behind the mouth, roughly one-quarter of the head length back from the snout.

Draw a faint centerline along the body. This line helps you keep the sucker disc and fins symmetrical. The sucker disc belongs on the underside of the head, not on the side of the body. Its long axis runs front-to-back, starting just behind the mouth and ending near the gill line.

1. Draw a tapered oval about 12 cm long and 4 cm wide at the widest point (hypothetical example).
2. Mark the front third as the head zone with a light vertical line.
3. Place the mouth at the front, slightly below the centerline.
4. Place the eye above the mouth, about one-quarter of the head length back.

Sucker Disc Placement

The sucker disc is a flattened oval on the underside of the head. In a side view, show it as a narrow band along the lower edge of the head; in a bottom view, show it as a full oval. Its front edge begins just behind the mouth, and its rear edge stops before the pectoral fins. The disc should not extend onto the body behind the head.

Use a light guide line to mark the disc's long axis. The disc's width is about half the head height. Keep the disc centered on the underside; it should not wrap around the side of the head in a side view.

1. Draw a light oval on the underside of the head, starting just behind the mouth.
2. End the oval near the gill line, before the pectoral fins begin.
3. Check that the disc's long axis is parallel to the body centerline.
4. In a side view, show only the lower edge of the disc as a narrow band.

Fin Placement

Remoras have one long dorsal fin running along the back toward the tail. The sucker disc is the modified first dorsal fin, located on the underside of the head. The anal fin mirrors the long dorsal fin on the underside. The pectoral fins sit just behind the head, below the midline. The tail fin is forked or rounded depending on style, but its base aligns with the body's end.

Place the long dorsal fin so it begins above the rear of the sucker disc, roughly one-third of the body length from the front, and runs to about three-quarters of the body length. The anal fin starts below the dorsal fin and runs a similar distance. Pectoral fins attach just behind the gill line, angled slightly downward.

1. Mark the start of the long dorsal fin above the rear of the sucker disc.
2. Draw the long dorsal fin from that point to about three-quarters of the body length.
3. Mirror the dorsal fin with the anal fin on the underside.
4. Attach pectoral fins just behind the gill line, angled slightly down.
5. Draw the tail fin at the rear, aligned with the body centerline.

Checking Proportions and Consistency

Use simple arithmetic to check placement. If the body is 12 cm long, the head zone is 4 cm. The sucker disc should start about 0.5 cm behind the mouth and end about 3.5 cm from the snout. The long dorsal fin begins about 4 cm from the snout and runs to about 9 cm from the snout. These numbers are hypothetical examples; measure your own drawing and keep units consistent.

Check that the sucker disc does not overlap the pectoral fins and that the dorsal and anal fins do not cross the tail fin. Valid alternatives include a slightly rounder body or a more forked tail, as long as the relative positions remain correct.

1. Measure the body length and divide by three to find the head zone.
2. Check the sucker disc starts behind the mouth and ends before the pectoral fins.
3. Check the long dorsal fin begins above the rear of the sucker disc.
4. Check the dorsal and anal fins run toward the tail without crossing it.

Worked example

A learner draws a remora 15 cm long. The head zone is 5 cm. Where should the sucker disc start and end, and where should the long dorsal fin begin? Use hypothetical measurements.

Four practice exercises

Common mistakes

• Placing the sucker disc on the side of the body instead of the underside of the head. Draw a centerline and keep the disc centered on the lower edge of the head; in side view, show only a narrow band.
• Extending the sucker disc past the gill line onto the body. End the disc near the gill line, before the pectoral fins begin.
• Putting the long dorsal fin too far forward, above the eye. Start the long dorsal fin above the rear of the sucker disc, about one-third of the body length from the snout.
• Attaching pectoral fins on the head itself. Attach pectoral fins just behind the gill line, below the midline.

Self-check rubric

• Sucker disc is on the underside of the head, starting behind the mouth and ending before the gill line.
• Long dorsal fin begins above the rear of the sucker disc, about one-third of the body length from the snout.
• Long dorsal fin runs toward the tail without crossing it.
• Anal fin mirrors the long dorsal fin on the underside.
• Pectoral fins attach just behind the gill line, below the midline.
• Body is a tapered oval with a clear head zone; valid alternatives in body roundness and tail shape are accepted.
• All measurements use consistent units and are checked against the learner's own drawing.
