Rough Toothed Dolphin Steno Bredanensis Kona Coast Big Island

Rough Toothed Dolphin Steno Bredanensis Kona Coast Big Island Encounter data from a 2010 shipboard line transect survey of the entire hawaiian islands eez was recently evaluated using beaufort sea state specific trackline detection probabilities for rough toothed dolphins, resulting in an abundance estimate of 72,528 (cv = 0.39) rough toothed dolphins (bradford et al. 2017) in the hawaii stock. For rough toothed dolphins during 2014 2018 are zero rough toothed dolphins within the hawaiian islands eez and 1.0 (cv = 1.6) dolphins outside of u.s. eezs (table 2, mccracken 2019). two unidentified cetaceans were taken in the dsll fishery that were considered to possibly be rough toothed dolphins, and three additional unidentified.

Rough Toothed Dolphin Steno Bredanensis Kona Coast Big Island Hawaii Credit: noaa fisheries. rough toothed dolphins are found throughout the world in tropical and warmer temperate waters. these small members of the dolphin family usually travel in small, tight knit groups of two to 20 individuals. their common name was based on the ridges found on their teeth, which are unique to this species. The steno feed on fish and squid as well as mollusks and cephalopods. rough toothed dolphins usually occur in tight knit groups of 3 to 7, though on the leeward coast of oahu, we usually see them in large pods of 40 100. pollutants have been detected in blubber analysis of rough toothed dolphins in hawaii. The rough toothed dolphin is a tropical to warm temperate species and is found in oceanic waters worldwide (miyazaki and perrin, 1994) (fig. 4). for instance, it prefers waters greater than 1500 m deep and is found mostly in waters deeper than 1000 m off hawai’i (baird, 2016, baird et al., 2008). this preference for very deep waters appears.
