The Belgian, who is a commanding figure with his large hair sitting on top of his six-foot-four frame, is the Toffees' top scorer this season having netted 11 times.
The 25-year-old believes that his appearance makes him an easy target for referees, who are quick to dish out the cards to the former Standard Liege man.
"During my first season at Everton I got 12 bookings," Fellaini told The Sun. "At the end of it a delegation of referees visited the club to explain why I had got so many yellow cards. But they ended up admitting some of the bookings were unduly harsh. I ask myself why they get given to me.
"No doubt it's because I am not someone who can pass by unnoticed. I am tall, and my hairstyle is easily recognised. I know how to give defenders problems.
"I can see them keeping a special eye on me - they are frightened of me."
Everton travel to Norwich City on Saturday in the Premier League.
