The seahorse, sometimes spelled sea horse or sea-horse, is a small ocean fish so named because of its resemblance to a horse's head. They range in size from less than an inch to 14 inches (2 to 35 cm).

Seahorses are very unique. Their tails are prehensile, meaning they use them to grab onto objects like plants. They are camouflaged, blending into their surroundings. Perhaps the most interesting characteristic is that the male, rather than the female, gives birth! Male seahorses have a pouch on their tail where the female deposits her eggs.

Seahorses are symbolic of beaches and the coast. There are also lots of cartoons that feature seahorse characters. In Disney's The Little Mermaid, the tiny Seahorse Herald made announcements, and large seahorses pulled underwater chariots. Sheldon was the "H2O intolerant" seahorse from Finding Nemo.

Step-by-Step Instructions for Drawing a Seahorse

1. Begin by drawing a circle. This will become the seahorse's head.

2. Draw another, larger, circle below the first. This will become the seahorse's torso and belly. Connect the two circles with a straight line. Note how the line passes through both circles. This will help you to sketch the seahorse's neck.

3. Draw two small rectangles, one crossing into the small circle and the other between the two circles. These will help form the mouth and neck of the animal.

4. Draw another straight vertical line passing through the center of both of the circles. It should extend above and below the circles. At the bottom of the line, draw a circle within a circle. This will help you sketch the seahorse's curly tail.

5. Use the rectangle attached to the head as a guide to sketch the sea horse's mouth. Use curved lines that connect the upper and lower inner corners of the rectangle. On the front of the rectangle, attach the curved lines using a sideways "V" shaped line.

7. Draw curved lines within the rectangle at the seahorse's neck. Then, draw a straight horizontal line through the circle that represents the body. It should cross the vertical line at a perpendicular angle.

8. Draw a curved line from the top of the vertical line to the bottom of the rectangle. This outlines the fin on the back of the seahorse's head. Then, draw a triangle from the back of the rectangle to the crossing of the perpendicular lines.

9. Draw a series of short, connected, curved lines along the curved line and triangle drawn in the last step. This forms a scalloped edge to the fin. Then, draw the seahorse's bulging eyes. Draw a circle within the head, using the vertical line as a guide. Use a curved line to enclose a half-circle on the front of the face.

10. Erase guide lines from the head. Draw a small, sideways trapezoid on the side of the face to indicate a small fin. Then, draw another straight, horizontal line below the first. Extend the lines of the neck fin and the curved line between the circles to meet at a point on top of this line.

12. Draw a square or diamond shape between the circles of the body and the tail. Connect it to the shape drawn in 10 using a curved line.

13. Add detail to your seahorse. Shade a large circle within each eye to form the pupils. Use a curved line to draw an eyebrow above the eye. Then, draw a series of connected curved lines from the base of the neck to the square above the tail. Connect the corner of the square to the bottom of the tail using a straight line.

17. Color your cartoon seahorse. We've chosen shades of green and orange for our illustration. In the wild, seahorses may be yellow, orange, cream, brown, red, black, or blue. Place your seahorse in an underwater scene! Is it an aquarium or an ocean coral reef? The choice is yours.
