Step 1: To start draw the body of the Piranha and then add the tail. Be sure to leave a little room to draw the mouth.
Step 2: Let's add a little detail now by adding lines to show the neck, then the eye. Draw three circles and shade in the middle one, and we can move on to the fins.
Step 3: Now we can draw two fins on the bottom of the fish, and then one on top. To finish add lines to fins and the tail, and you're done!
