One interesting phenomenon that has evolved in the English language is the use of poetic and interesting collective nouns. There is an old English hunting tradition of using nouns of assemblage that are specific to certain kinds of animals, and that is where many of these come from. Sometimes multipe names are even used for the same animal depending on the situation. Ducks are a good example. A dopping of ducks is diving, a paddling of ducks are swimming, a raft of ducks are floating, and a plump of ducks are flying. Below is a list of some other interesting examples, and you can find a description and history on wikipedia as well as specific pages for birds, fish, mammals, and reptiles.
