Finding Dory that cried out to be made." Conservationists warned that, very much like "Finding Nemo", the film could lead to uninformed customers buying blue tangs for home aquariums. Blue tangs cannot be bred in captivity and have to be caught in the wild. They are related to surgeonfish and exhibit razor-sharp spines on both sides of the tail that can inflict formidable wounds. While promoting the film, actress Ellen DeGeneres reminded audiences that Nemo and Dory's real-life home, the Great Barrier Reef, is under enormous threat, mostly due to coral bleaching, a process induced by climate change, which has killed coral
Forgetful functor set, privileged subsets of the underlying set, etc.) which may satisfy some axioms. For these objects, a commonly considered forgetful functor is as follows. Let formula_1 be any category based on sets, e.g. groups—sets of elements—or topological spaces—sets of 'points'. As usual, write formula_2 for the objects of formula_1 and write formula_4 for the morphisms of the same. Consider the rule: The functor formula_11 is then the forgetful functor from formula_1 to formula_13, the category of sets. Forgetful functors are almost always faithful. Concrete categories have forgetful functors to the category of sets—indeed they may be "defined" as those categories
