Group size and feeding success in strand‐feeding bottlenose dolphins (Tursiops truncatus) in Bull Creek, South Carolina

An adaptive bottlenose dolphin foraging tactic, “shipside feeding,” using container ships in an urban estuarine environment

“…As a result, dolphins and humans in coastal areas often overlap in habitat and resource use. While bottlenose dolphins have been observed using natural surfaces to trap fish, mostly including the beach during low tides (Duffy‐Echevarria et al, 2008; Gisburne & Connor, 2015; Hoese, 1971; Jiménez & Alaver, 2015; Mullin et al, 1990; Petricig, 1995; Rigley et al, 1981; Sargeant et al, 2005; Silber & Fertl, 1995), they have also been reported using nonnatural barriers to trap fish against, including the nylon netting of fish farms in Italy (López, 2006) and gill nets on commercial fishing boats in North Carolina (Cox et al, 2003), seawalls (Wells, 2019), and possibly the underwater walls of manmade channels (Ronje et al, 2018). Weiss (2006) described “barrier‐feeding” in Sarasota Bay, in which bottlenose dolphins used a variety of surfaces to herd fish, including natural surfaces and the sides of boats.…”

Determinación de peces presas consumidos por toninas (Tursiops truncatus) que vararon en la Isla del Carmen, Campeche

“…Tursiops truncatus ha mostrado diferentes técnicas o estrategias de alimentación (Connor, Wells et al, 2000;Nowacek, 2002;Torres y Read, 2009). Pueden vararse voluntariamente luego de haber conducido a los peces hasta la playa (Duffy-Echevarría et al, 2008;Gisburne y Connor, 2015;Silber y Fertl, 1995), utilizar esponjas como protección en el rostro para obtener peces escondidos bajo rocas (Patterson y Mann, 2011), usar a moluscos como herramienta de alimentación e ingesta (Allen et al, 2011), golpear con la aleta caudal en aguas somera de zonas de camas de pastos marinos para lograr que los peces salgan de su refugio (Connor, Heithaus et al, 2000).…”

An experimental assessment of social tolerance and den ecology in a high-density octopus population

“…The social behaviour of animals regularly receives interest in the academic literature, exploring taxa across the animal kingdom (Economakis and Lobel 1998;Ritz et al 2011) and the degree of interaction they have with conspecifics. Nearly all motile marine animals interact with other members of its species at some point in their lives, and some species aggregate together to improve feeding success (Gisburne and Connor 2015), protection against predators (Magurran 1990), and/or mate accessibility (Baeza 2008;Subramoniam 2013). Consequently, the commonly used definition of 'social behaviour' refers to all intraspecific interactions, from aggressive, through cooperative, sexual and parental (Rubenstein and Rubenstein 2013).…”
