The Bombay duck lives in the tropical areas of the Indo-Pacific. The fish is also known as "strange fish" because of its discontinuous distribution along the
Type system when called, at run-time. Duck typing differs from structural typing in that, if the "part" (of the whole module structure) needed for a given local computation is present "at runtime", the duck type system is satisfied in its type identity analysis. On the other hand, a structural type system would require the analysis of the whole module structure at compile time to determine type identity or type dependence. Duck typing differs from a nominative type system in a number of aspects. The most prominent ones are that for duck typing, type information is determined at runtime (as contrasted to compile
