Step 1: Start by drawing the mouth for which we draw a "C" shape and then draw a circular, curved line above it for the head.
Step 2: Now we draw the fins. First we draw a a loop-like fin at the top of the head and two smaller, curved "V" shaped fins at the bottom leaving a small space between both.
Step 3: Next we draw the tail for which we draw a curved line going down and toawrds the right, starting from behind the top fin. Draw a fork like tail fin at the end of this curved line. Now draw a horizontal line between both bottom fins and further join the bottom fins to the end of the tail with a curved line.
Step 4: Now we add detail by drawing a circle for the eye with a shaded circle for the pupil inside, a small curved line below the eye for the mouth, a tiny circle above the eye for the hole and a curved line from the middle of the tail to the middle of the body.
