Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb) (Maui’s Dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 LT; 11 ST) (the Orca or Killer Whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacean order, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals and their often friendly appearance and seemingly playful attitude have made them popular in human culture

It is not so easy to define exactly what we mean by a lighthouse, and various organizations and individuals 
have used very different definitions when describing or classifying lighthouses. Clearly, all lighthouses are lighted aids to navigation, but not all lighted aids are considered to be lighthouses.
Some definitions are not controversial. An aid to navigation is a structure placed on or near navigable water to provide visual guidance to mariners. A beacon is an aid to navigation that is fixed in place (that is, not floating). A lighted beacon or lightbeacon is a beacon displaying a light, while an unlit beacon is called a daybeacon. Often, a lighted beacon is simply called a light.
In this Directory, a lighthouse is a lightbeacon having a height of at least 4 meters (13 ft) and a cross-section, at the base, of at least 4 square meters (43 sq ft). This simple definition does not require that a lighthouse have any particular form or appearance. The structure of a lighthouse may be enclosed, partially enclosed, or completely open.
