'''Please do not over-categorize this category.''' Under no circumstances should this category be placed in "Enemy of <X>" categories — especially of the various Doctors — as it ''completely'' overburdens the category structure of this wiki. Given the number of pages that are related to both the Homo Reptilia and the Doctors, placing [[:Category:Silurians and Sea Devils]] within [[:Category:Third Doctor enemies]], et al, '''totally''' breaks the category structure of the wikia. Instead, place the ''page'' [[Silurian]] within those "enemies" categories.
