BEHAVIORAL STUDIES OF THE MARINE TUCUXI, Sotalia guianensis (Cetacea: Delphinidae) IN BRAZIL: A REVIEW OF SAMPLING METHODS AND TERMINOLOGY.
Abstract
The
marine tucuxi (Sotalia guianensis Van Bénéden, 1864) is a small delphinidae currently under investigation by several different research groups along the Brazilian coast. Due to its habit of swimming in murky waters and
to some morphological characteristics, studying the behavior of this animal is difficult, yet behavioral studies with S. guianensis are becoming more frequent in Brazil. However, the methods employed by different studies,
including sampling techniques and terminology are not standardized, thus hindering comparisons of the results and general conclusions of such studies. This paper reviews the current state of knowledge about the behavior
of this species while attempting to revise the terms, definitions and methods employed by different studies.
