Connecting link is an organism having characteristics of two different group of organisms .

e.g, duck-billed platypus ( scientific name Ornithorhynchus anatinus) is a connecting link between reptiles and mammals i.e, it has mammary glands to feed its young ones like other mammals e.g human being, cow, buffalo etc., and it lays hard-shelled egg with a large amount of yolk like reptiles , so duck-billed platypus is a connecting link between two evolutionary groups viz., reptiles and mammals.
