Surface patterns of Sotalia guianensis (Cetacea: Delphinidae) in the presence of boats in Port of Malhado, Ilhéus, Bahia, Brazil

Latin American Journal of Aquatic Research, 2013
Interactions with boats can cause several behavioural changes in cetaceans. The purpose of this research is to analyse if Guiana dolphins, Sotalia guianensis, change their surfacing patterns in the presence of different boat categories, and their contact

Progress report on the Sotalie study (Sotalia guianensis)

Les dauphins de rivières et notamment les sotalies de Guyanes (Sotalia guianensis) sont des animaux discrets et ainsi difficiles à étudier. Pour étudier le comportement de ces animaux, en particulier leurs zones de présence, leurs habitudes journalières ou encore leurs modes de communication, l’acoustique passive est une méthode très efficace.

Underwater audiogram of a tucuxi (Sotalia fluviatilis guianensis)

The Journal of the Acoustical Society of America, 1998
Using a go/no go response paradigm, a tucuxi (Sotalia fluviatilis guianensis) was trained to respond to pure-tone signals for an underwater hearing test. Auditory thresholds were obtained from 4 to 135 kHz. The audiogram curve shows that this Sotalia had an upper limit of hearing at 135 kHz; from 125 to 135 kHz sensitivity decreased by 475 dB/oct. This
