Upon visiting the South American coast in the mid 1400s, Amerigo Vespucci named present day Venezuela, which translates to little Venice, because the stilt dwellings that sat over the water within the mangrove forest reminded him of the Venice canals. A fluctuation of ten degrees in a short period of time is enough stress to damage the plant and freezing temperatures for even a few hours can kill some mangrove species.
