This study assessed the extent of sexual dimorphism in striped dolphin (Stenella coeruleoalba) cranial size and shape off the South African coast. There were no sig- nificant differences in the weight of any paired organs (adrenal glands, kidneys, lungs, ovaries, testes), and all were significantly correlated with BM. presence of different subspecies, but an additional independent line of evidence is
That's on one hand kinda macabre to do with an animal you've known and taken care of, but on the other hand extremely interesting. Other examples of cranial telescoping in mammals on the DigiMorph site are the lowland tapir and Baird's tapir. Ross 1977, 1984; Ross and Cockcroft 1990; Sarasota Bay, Florida, to determine whether, lantic coast of Florida, including the Florida, counted by hand. (Order: Cetacea) revealed by computed tomography: implications for cetacean
Scatterplot of internal nares width versus height of braincase for female bottlenose dolphins from Texas and Florida. Se observó un número de alvéolos maxilares promedio de 22 dientes para cada hemi-maxila, siendo identificados cuatro especímenes como de hábitat costero y solo uno como oceánico. to grow to slightly longer lengths than females. The corrupted, and subsequently reacquired images were coronal slices 320-321, 533-534, and 621-628. in Chinese waters, Oeseological differences between two sympatric forms of bottlenose dolphin (genus Tursiops) in Chinese waters, Natural History of Bottlenose Dolphins Along the Central Atlantic Coast of the United States, Comments on Australian Bottlenose Dolphins and the Taxonomic Status of Tursiops aduncus (Ehrenberg, 1832), Differences in external morphology of two sympatric species of bottlenose dolphins (Genus Tursiops) in the waters of China, The Sierra Club Handbook of Whales and Dolphins, Administration and development of a new Sustainable Coastal Systems program, Growth of bottlenose dolphins (Tursiops truncatus) from the Indian River Lagoon System, Florida, USA, Craniometry of bottlenose dolphins (Tursiops truncatus) from the Adriatic Sea, Patterns of Bottlenose Dolphin, Tursiops truncatus, Strandings in Texas. The skulls of 95 adult bottlenose dolphins (47 females and 43 males, 5 of unknown sex) were morphometrically analyzed. Many studies of morphological variation that aim to identify stocks or populations deal with skull characters (e.g. In addition, scarring of the dorsal fin occurred more frequently on males than on females. Leatherwood, S. and Reeves, R., eds. 1984. Dolphins are the most diverse family of living marine mammals and include species such as the bottlenose dolphin and the killer whale. Further study of patterns of asymmetry in fossil and Recent cetaceans is needed to evaluate these different scenarios. Nature 413: 259-260. morphological characteristics of each group corresponded well with two ecotypes of Results revealed two distinct morphological groups, with the smaller cluster comprised mainly of specimens from the cold temperate region off the west coast and the larger cluster comprised of specimens mainly from the warm temperate and subtropical regions off the south and east coast, respectively. All rights reserved. Sexual dimorphism within the Adriatic population was analyzed while the average morphometric values of Adriatic specimens were compared with published values for the genus Tursiops from different geographical areas. The bones are lighter than the bones of land mammals. The Bottlenose Dolphin is sleek and streamlined and can travel at speeds of up to 35 km per hour. This study aimed to shed light on morphological variation of the genus Tursiops in South African waters using geometric morphometrics and to distinguish morphological groups and variation in these groups. Bottlenose Dolphins prefer shallow, inshore waters and are commonly seen off the coasts of Hawaii and Florida. As noted above, slices 320-321, 533-534, and 621-628 were corrupted and reacquired at a later point.
These data on organ weights of bottlenose dolphins, when interpreted with SBL, BM, and age, are significant tools for pathologists and vet- erinarians interpreting animal health status. Skulls of Tursiops truncatus from Peru and Ecuador were examined to explore geographical variation by traditional morphometrics and multivariate analysis. 3D Volume Rendering Technique (VRT) skull reconstruction from CT scans of the head of a Bottlenose Dolphin (Tursiops truncatus).
