Codas have led researchers to propose that sperm whales belong to distinct cultural clans, but it is presently unclear if they also convey individual information. Coda clicks comprise a series of pulses and the delay between pulses is a function of organ size, and therefore body size, and so is one potential source of individual information. Another potential individual-specific parameter could be the inter-click intervals within codas. To test whether these parameters provide reliable individual cues, stereo-hydrophone acoustic tags (Dtags) were attached to five sperm whales of the Azores, recording a total of 802 codas. A discriminant function analysis was used to distinguish 288 5 Regular codas from four of the sperm whales and 183 3 Regular codas from two sperm whales. The results suggest that codas have consistent individual features in their inter-click intervals and inter-pulse intervals which may contribute to individual identification. Additionally, two whales produced different coda types in distinct foraging dive phases. Codas may therefore be used by sperm whales to convey information of identity as well as activity within a social group to a larger extent than previously assumed.<\/jats:p>","DOI":"10.1121\/1.4949478","type":"journal-article","created":{"date-parts":[[2016,5,20]],"date-time":"2016-05-20T03:28:09Z","timestamp":1463714889000},"page":"2860-2869","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":41,"title":["Sperm whale codas may encode individuality as well as clan identity"],"prefix":"10.1121","volume":"139","author":[{"given":"Cl\u00e1udia","family":"Oliveira","sequence":"first","affiliation":[{"name":"Universidade dos A\u00e7ores Marine and Environmental Sciences Centre and Institute of Marine Research, Departamento de Oceanografia e Pescas, , 9901-862 Horta, Portugal"}]},{"given":"Magnus","family":"Wahlberg","sequence":"additional","affiliation":[{"name":"University of Southern Denmark Department of Biology, , Campusvej 55, DK-5230 Odense M, Denmark"}]},{"given":"M\u00f3nica A.","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade dos A\u00e7ores Marine and Environmental Sciences Centre and Institute of Marine Research, Departamento de Oceanografia e Pescas, , 9901-862 Horta, Portugal"}]},{"given":"Mark","family":"Johnson","sequence":"additional","affiliation":[{"name":"Scottish Oceans Institute, University of St. Andrews Sea Mammal Research Unit, , St. Andrews, Fife KY16 8LB, United Kingdom"}]},{"given":"Ricardo","family":"Antunes","sequence":"additional","affiliation":[{"name":"Wildlife Conservation Society Ocean Giants Program, Global Conservation Programs, , 2300 Southern Boulevard, Bronx, New York 10460, USA"}]},{"given":"Danuta M.","family":"Wisniewska","sequence":"additional","affiliation":[{"name":"Aarhus University Zoophysiology, Department of Bioscience, , Ny Munkegade 116, DK-8000 Aarhus C, Denmark"}]},{"given":"Andrea","family":"Fais","sequence":"additional","affiliation":[{"name":"University of Veterinary Medicine Institute for Terrestrial and Aquatic Wildlife Research, , Bischofsholer Damm 15, 30173 Hannover, Germany"}]},{"given":"Jo\u00e3o","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Universidade dos A\u00e7ores Marine and Environmental Sciences Centre and Institute of Marine Research, Departamento de Oceanografia e Pescas, , 9901-862 Horta, Portugal"}]},{"given":"Peter T.","family":"Madsen","sequence":"additional","affiliation":[{"name":"Aarhus University Zoophysiology, Department of Bioscience, , Ny Munkegade 116, DK-8000 Aarhus C, Denmark"}]}],"member":"231","published-online":{"date-parts":[[2016,5,19]]},"reference":[{"key":"2023072807203595900_c1","unstructured":"Antunes, R.
