Step 1: Begin your perch with the head by drawing a sideways triangular cylinder with two semi-circles where the point would be.
Step 2: Add the eye by drawing a large, semi-shaded circle in the narrow end of the head.
Step 3: Next, draw the body by adding two curved lines moving back from the head. From the top line, add several "V" shapes coming down for the stripes.
Step 4: Now draw the fins. Add two semi-circles to the top of the body, and a trapazoid below it. In the center of the body, draw an incomplete triangle shape. Add lines all along each fin.
Step 5: Finally, draw the tail by drawing a "3" shape at the back of the body. Add several short lines along it.
