Morfologia do sincrânio do boto-cinza, Sotalia guianensis (P.J. van Bénéden) (Cetacea, Delphinidae)

Abstract: Apresenta-se uma descrição da morfologia comparada do sincrânio de Sotalia guianensis (P.J. van Bénéden, 1864), incluindo suas variações ontogenéticas e intra-específicas. As descrições foram baseadas em 51 crânios completos ou parciais depositados na coleção do laboratório de Mamíferos Aquáticos, do Departamento de Ecologia e Zoologia, CCB, Universidade Federal de Santa Catarina. O sincrânio é bastante homogêneo e manifesta sua assimetria na morfologia dos ossos, passagens nasais e forames. O rostro é proporc… Show more

“…The characters that refer to the position or counting of the foramina in the maxillary bone (characters 16, and 17) were quite variable among the specimen. Our results corroborate the data presented by Fettuccia et al (2009) and Simões-Lopes (2006). According to these authors, the foramina of the facial region of S. guianensis are variable as refers to the number, and position.…”

“…These skulls were used to compare the bone development with the time of formation and fusion of each bone structure. The exclusion from the analysis of the qualitative data not associated to the development and displaying variable distribution among the specimens, according to Fettuccia et al (2009) and Simões-Lopes (2006), was necessary to associate the characters with the age estimates (features 16, 17, and 23). Besides these, more eight characters (features 1, 2, 21, 23, 25, 26, 27 and 29) were excluded, as they did not present any significant variation among the states of the character.…”

“…Therefore, for this study we used the data from the right periotic -timpanic complex, and from the left complex when the right was not available. The definition of the periotic -timpanic bone complex followed Simões-Lopes (2006), while the osteological terminology and anatomic orientation followed Mead & Fordyce (2009).…”

“…Animais encalhados ou pegos em redes também foram fonte de pesquisa para Daura-Jorge et al( 2011), mas avaliando especificamente a dieta dos animais por meio do conteúdo estomacal. Outro fator corporal dos animais foi estudado através de anatomia comparada em se que investigou os crânios de S. guianensis depositados em uma coleção zoológica (Simões-Lopes, 2006).…”
