is this chi square value really wrong? !!!?

i’m currently doing my stats test for my biology coursework and i think i have done the chi squared wrong although i have no idea how! i am working with two variables and 5 degrees of freedom investigating how the size of limpets relates to the type of shore. i got a huge chi result of 81.06 but the critical value is only 11.07 at 95%. is this really wrong or just very certain! lol. PLEASE help!
