Steno bredanensis (Cetacea: Delphinidae)

Abstract: Steno bredanensis (Cuvier in Lesson, 1828) is a small odontocete commonly called the rough-toothed dolphin. A slender, gray dolphin with a slightly darker cape, this species is most easily distinguished from other small delphinids by a gradually sloping forehead and a long rostrum. It is the only species in the genus Steno. Despite reports of sightings or stranded specimens from all tropical and subtropical oceans, the species is thought to typically occur in low abundance. The conservation status of S. bredan… Show more

“…The rough-toothed dolphin (Steno bredanensis) has been implicated in depredation of Hawaiian recreational and commercial hook and line fisheries for billfish and tuna (Nitta & Henderson, 1993), and it is reported that this species can remove 20 to 50% of the bait set in some areas (West et al, 2011). However, reports of depredation by this species have primarily been anecdotal in nature, and no specific accounts could be located by Hamer et al (2012) in their review.…”

“…Se caracteriza por sus hábitos pelágicos, encontrándose generalmente en aguas oceánicas profundas y ocasionalmente cerca de la costa, con profundidad de 15 m (Delgado 1994;West et al 2011). Suelen viajar solitarios o en grupos de varios tamaños, que van desde dos hasta 160 animales (Watkins et al 1987;Baird et al 2008).…”

“…Se distingue de otros delfínidos pequeños debido a que la porción frontal del cráneo se inclina gradualmente, formando un rostro largo y estrecho, con ausencia de una separación entre el melón y el hocico (West et al 2011). Tiene la aleta dorsal falcada con terminación en punta y coloración oscura, con sombras negras, blancas y grises, en el dorso se forma una franja negra que se vuelve angosta entre el rostro y la aleta dorsal, haciéndose ancha por detrás de ésta, los costados son grisáceos y el vientre blanco (Carwardine 2002;Urbán y Guerrero-Ruíz 2008).…”

“…Steno bredanensis is a pantropical species (West et al 2011) found along the Brazilian coast, with regular records along the coast of São Paulo (Martuscelli et al 1996, Santos et al 2010. This dolphin has a seemingly diverse diet (West et al 2011) that includes large fish like 50 cm-long remoras (Echeneidae, Wedekin et al 2004) and 1.5 m-long Dolphinfish Coryphaena hippurus (Coryphaenidae, Pitman & Stinchcomb 2002); the species has been suggested to be specifically adapted to handle such prey (Pitman & Stinchcomb 2002), an affair that requires dismembering and results in scraps that may float into reach of attending seabirds.…”
