Resumo: | The vertebral morphology of the estuarine dolphin, Sotalia guianensis (Cetacea, Delphinidae). We present a description of the backbone of the marine tucuxi (Sotalia guianensis) vertebrae (n=34), including the variations in the vertebral formula (n=32) (UFSC-Universidade Federal de Santa Catarina): Ce7 , T12 , L10_12, Ca23_25 == 52-56. Species diagnostic characters and intraspecific variations are presented. Cervical ribs occur in 22.5% of the samples. The metapophyses start from the fourth thoracic vertebra, and the zigapophyses start at the cervical level, being observed up to T11 . The inclination of the transverse processes and neurapophyses is most reduced around L5 or L6 . Transverse processes on caudal vertebrae disappear between Ca9 and Can . The neurapophyses, neural arches and metapophyses are observed up to Ca n or Can. Caudal foramina appear between Ca3 and Ca6. The height of the vertebral body increases up to Ca n, then starts to decrease. The maximum width is found around Ca6, where the vertebral body becomes laterally compressed. The length of the vertebral body increases from the last cervical to T7 andthen remains constant up to Ca 13, decreasing from then on. This is the first study to take into account intraspecifc shape and count variations, representing an improvement over the traditional typologic approach. |

Caracteres diagnósticos da espécie e variações intra-especificas são aqui apresentadas. Costelas cervicais ocorreram em 22,5 % da amostra (n=31). As metap6fises iniciam-se a partir da quarta torácica e as zigapófises surgem nas cervicais, podendo ser observadas até a T 11 . Os processos transversos e neural encontram-se mais eretos em torno da L5 OU L6. Nas vértebras caudais, os processos transversos deixam de existir entre a Ca 9 e Ca13 . 0 processo neural, o arco neural e as metapófises são observados até a Ca 13 ou Ca 15 . Os foramens caudais surgem entre a Ca3 e Ca6 . A altura do corpo da vertebra apresenta-se crescente até a Ca n, onde começa a diminuir. A largura maxima do corpo da vértebra é encontrada em torno da Ca6 , sendo que a partir dai o corpo da vértebra torna-se lateralmente comprimido. 0 comprimento do corpo da vértebra cresce entre a última cervical e a T7 e dai em diante mantém-se constante até a Ca n, diminuindo a partir deste ponto. Este é o primeiro estudo a considerar as variações intraespecificas de forma e contagem, oferecendo avanços sobre a abordagem tipológica tradicional.Universidade Federal de Santa Catarina2004-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/23252Biotemas; v. 17 n. 2 (2004); 125-1482175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/23252/20974Copyright (c) 2004 Daniela de Castro Fettuccia, Paulo César Simões-Lopeshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFettuccia, Daniela de CastroSimões-Lopes, Paulo César2022-11-21T11:18:55Zoai:periodicos.ufsc.br:article/23252Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:18:55Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
