Amongst these are its all-white colour and the absence of a <a href="/wiki/Dorsal_fin" title="Dorsal fin">dorsal fin</a>, which allows it to swim under ice with ease.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> It possesses a distinctive protuberance at the front of its head which houses an <a href="/wiki/Animal_echolocation" title="Animal echolocation">echolocation organ</a> called the <a href="/wiki/Melon_(whale)" class="mw-redirect" title="Melon (whale)">melon</a>, which in this species is large and deformable. The beluga's body size is between that of a dolphin and a true whale, with males growing up to 5.5 m (18 ft) long and weighing up to 1,600 kg (3,530 lb). This whale has a stocky body. Like many cetaceans, a large percentage of its weight is <a href="/wiki/Blubber" title="Blubber">blubber</a> (subcutaneous fat). Its sense of hearing is highly developed and its <a href="/wiki/Animal_echolocation" title="Animal echolocation">echolocation</a> allows it to move about and find breathing holes under sheet ice. </p><p>Belugas are <a href="/wiki/Gregarious" class="mw-redirect" title="Gregarious">gregarious</a> and form groups of 10 animals on average, although during the summer, they can gather in the hundreds or even thousands in <a href="/wiki/Estuary" title="Estuary">estuaries</a> and shallow coastal areas. They are slow swimmers, but can dive to 700 m (2,300 ft) below the surface. They are <a href="/wiki/List_of_feeding_behaviours" title="List of feeding behaviours">opportunistic feeders</a> and their diets vary according to their locations and the season.
