Sensitivity of a tucuxi (Sotalia fluviatilis guianensis) to airborne sound
The Journal of the Acoustical Society of America, 2005Auditory systems of cetaceans are considered highly specialized for underwater sound processing, whereas the extent of their hearing capacity in air is still a point of issue. In this study, the sensitivity to airborne sound in a male tucuxi (Sotalia fluviatilis guianensis) was tested by means of a go/no go response paradigm.

Whistles of boto, Inia geoffrensis, and tucuxi, Sotalia fluviatilis
The Journal of the Acoustical Society of America, 2001Whistles were recorded and analyzed from free-ranging single or mixed species groups of boto and tucuxi in the Peruvian Amazon, with sonograms presented. Analysis revealed whistles recorded falling into two discrete groups: a low-frequency group with maximum frequency below 5 kHz, and a high-frequency group with maximum frequencies above 8 kHz and ...

Whistles of tucuxi dolphins (Sotalia fluviatilis) in Brazil: Comparisons among populations
The Journal of the Acoustical Society of America, 2005A quantitative and comparative analysis of the acoustic whistles parameters of tucuxi dolphins (Sotalia fluviatilis) from eight areas in Brazilian waters were conducted. Tucuxi produced mainly upsweep whistles, and despite their similar characteristics to other delphinids, whistles were shorter and less complex in shape.

Distribution of the South American dolphin Sotalia fluviatilis
Canadian Journal of Zoology, 1991The marine form of the South American dolphin Sotalia fluviatilis has an extensive and possibly continuous distribution, from the Florianópolis region, Brazil (27°35′S, 48°34′W), north to Panama (~9°22′N, 79°54′W). The high number of records from 25–20°S is due to the presence of many observers in those latitudes.

Molecular Ecology Notes, 2007
AbstractTwelve dinucleotide polymorphic microsatellite loci were isolated from the marine tucuxi dolphin (Sotalia guianensis). Levels of genetic diversity were assessed using 34 individuals from the coasts of Rio de Janeiro and Pará, Brazil. Numbers of alleles varied between two and 14, and observed and expected heterozygosities ranged from 0.040 to 0 ...

Whistles of small groups of Sotalia fluviatilis during foraging behavior in southeastern Brazil
The Journal of the Acoustical Society of America, 2005Whistle emissions were recorded from small groups of marine tucuxi dolphins (Sotalia fluviatilis) in two beaches located in an important biological reserve in the Cananéia estuary (25°03′S, 47°58′W), southeastern Brazil. A total of 17h of acoustic data was collected when dolphins were engaged in a specific feeding foraging activity.
