The Ecological Conditions That Favor Tool Use and Innovation in Wild Bottlenose Dolphins (Tursiops sp.)

Abstract: Dolphins are well known for their exquisite echolocation abilities, which enable them to detect and discriminate prey species and even locate buried prey. While these skills are widely used during foraging, some dolphins use tools to locate and extract prey. In the only known case of tool use in free-ranging cetaceans, a subset of bottlenose dolphins (Tursiops sp.) in Shark Bay, Western Australia habitually employs marine basket sponge tools to locate and ferret prey from the seafloor. While it is clear that s… Show more

“…procure and wear basket sponges on their beaks while lightly scouring the seafloor for prey in deep (8-13 m) channels ( Fig. 1) [9][10][11][12] . Sponging is the bestdocumented case of tool use by wild cetaceans and is unique among wildlife in that only a small subset of the population uses tools.…”

“…This exceptional case of tool-use heterogeneity allows us to test for preferential affiliation based on tool-use. To date, 55 dolphins have been documented habitually using sponges in the eastern gulf of Shark Bay 12 , although sponging also occurs in the western gulf 13 . Only calves of spongers become spongers (24 offspring to date), but 8 offspring of spongers never adopted sponging.…”

“…Like many tool using species, ecological factors (such as the physical characteristics of prey) play a critical role in explaining complex behaviors (Collins andMcGrew 1987, Patterson andMann 2011). Future studies would benefit from quantifying the cost and benefits of learning to use tools, as well as further exploration to how individuals learn to use tools.…”

“…En el caso de los útiles, hoy en día, sabemos que distintos primates utilizaron herramientas (Schick y otros, 1999;Van Schaik, Deaner y Merrill, 1999;Mercader, Panger y Boesch, 2002), especialmente monos capuchinos (Fragaszy y otros, 2004;Ferreira, Emidio y Jerusalinsky, 2010;Proffitt y otros, 2016) y macacos (Gumert, Kluck y Malaivijitnond, 2009;Haslam y otros, 2013), además de otros animales como peces, osos y elefantes (Hart y otros, 2001;Deecke, 2012;Patterson y Mann, 2011) para algunas de sus funciones básicas, como la alimentación o la higiene personal y, por lo tanto, la humanidad no es la única que emplea o ha empleado herramientas.…”
