They were studied by Fifth years in Defence Against the Dark Arts, which was taught by Professor Quirinus Quirrell at the time, during 1991. As Dolores Umbridge said that Quirrell's classes were the only ones which would pass her inspection, iguanas are likely part of the curriculum approved by the Ministry of Magic Dolores Umbridge while talking to her Fifth years in 1995.
