In the U.S., this well-studied intelligent species can be found all throughout the Atlantic coast, the Gulf of Mexico and the Caribbean as well as along the Pacific coast from Washington to California. Measuring from six to thirteen feet and weighing up to 1,400 lbs, these dolphins can be seen in open ocean, near the coastline or in estuaries, bays and harbors.<\/p>\n<p>The bottlenose\u2019s close proximity to human beings creates one of its greatest threats. Becoming entrapped in fishing gear is one of the major threats affecting the populations of bottlenose around the world, as well as contamination from industrial pollution and harmful algae blooms. \u00a0<\/p>\n<p>In five of the population stocks along the Atlantic coast, bottlenose populations are classified as \u201c<a href=\"https:\/\/www.fisheries.noaa.gov\/laws-and-policies\/glossary-marine-mammal-protection-act?ref=beautifulpublicdata.com#strategic-and-depleted-stocks\">depleted<\/a>\u201d.<\/p>\n<p>In addition to simply counting and identifying the dolphins, the researchers set out to understand the social networks that the dolphins adhered to. <\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.beautifulpublicdata.com\/content\/images\/2023\/04\/Screenshot-2023-04-10-at-2.09.09-AM.png\" alt=\"A screenshot of a figure from the research paper showing a network diagram made up of three main clusters of dolphins. \" loading=\"lazy\" width=\"1774\" height=\"1190\"  ><figcaption>A figure from the research paper illustrating the three distinct clusters of dolphins observed in the study.
