These \"throws\" occur in several contexts at a site in Jervis Bay, Australia, including in interactions with other octopuses. Material thrown in interactive contexts frequently hits other octopuses. Some throws appear to be targeted on other individuals, as suggested by several kinds of evidence: Throws in interactive contexts were more vigorous than others, and more often used silt, rather than shells or algae. High vigor throws were more often accompanied by uniform or dark body patterns than other throws. Some throws were directed differently from beneath the arms and such throws were more likely to hit other octopuses. Throwing at other individuals in the same population, as apparently seen in these octopuses, is a rare form of nonhuman projectile use, previously seen only in some social mammals.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0276482","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T13:48:07Z","timestamp":1668001687000},"page":"e0276482","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["In the line of fire: Debris throwing by wild octopuses"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1519-3661","authenticated-orcid":true,"given":"Peter","family":"Godfrey-Smith","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Scheel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie","family":"Chancellor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Linquist","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Lawrence","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"pone.0276482.ref001","doi-asserted-by":"crossref","first-page":"107e113","DOI":"10.1016\/j.jhevol.2014.09.004","article-title":"Clavicle length, throwing performance and the reconstruction of the Homo erectus shoulder","volume":"80","author":"NT Roach","year":"2015","journal-title":"Journal of Human Evolution"},{"key":"pone.0276482.ref002","doi-asserted-by":"crossref","first-page":"807","DOI":"10.1038\/385807a0","article-title":"Lower Palaeolithic hunting spears from Germany","volume":"385","author":"H.
