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 Forgetful functor In mathematics, in the area of category theory, a forgetful functor (also known as a stripping functor) 'forgets' or drops some or all of the input's structure or properties 'before' mapping to the output. For an algebraic structure of a given signature, this may be expressed by curtailing the signature: the new signature is an edited form of the old one. If the signature is left as an empty list, the functor is simply to take the underlying set of a structure. Because many structures in mathematics consist of a set with an additional added structure, a forgetful
