The moose (Alces alces) – North America – or elk –Eurasia – is the largest and heaviest extant species in the deer family. Moose are distinguished by the broad, palmate (open-hand shaped) antlers of the males; other members of the deer family have antlers with a dendritic ("twig-like") configuration. Moose is an Algonquin (a Native American tribe) term that means twig eater. Male moose are called bulls. Females are called cows. Moose prefer a swampy, boggy habitat but are also found in woodlands. The European elk is almost identical to a moose. Thus when Europeans talk about an elk they are usually referring to what Americans call a moose – but the European elk is slightly smaller than moose found in North America.
