Lipids of freshwater dolphinSotalia fluviatilis: Comparison of odontocete bioacoustic lipids and habitat

Lipids, 1975
AbstractThe melon and jaw lipids of the freshwater dolphinSotalia fluviatilis are composed mainly of isovaleroyl wax esters and diisovaleroyl triglycerides. The blubber fat contains only a trace of wax ester and is mostly tri‐ (long chain) and monoisovaleroyl triglycerides.

RETINAL TOPOGRAPHY AND VISUAL ACUITY IN THE RIVERINE TUCUXI (SOTALIA FLUVIATILIS)

Marine Mammal Science, 1999
AbstractThe distribution and size of ganglion cells in the retina of two tucuxi were investigated. Retinal cell size varied from 10 to 50 μm with a polymodal size distribution; major groups were seen with sizes of 8‐20, 21‐35, and more than 35 μm. Ganglion cells concentrated at two spots of the highest density in the nasal and temporal quadrants, about

Purification and Characterization of a Liver-derived β-N-Acetylhexosaminidase from Marine Mammal Sotalia fluviatilis

The Protein Journal, 2010
A beta-N-Acetylhexosaminidase (EC 3.2.1.52) was purified from hepatic extracts of Sotalia fluviatilis, order Cetacea. The protein was purified by using ammonium sulfate fractionation and four subsequent chromatographies (Biogel A 1.5 m, Chitin, Deae-Biogel and hydroxyapatite resins).

Age estimation of marine tucuxi dolphins (Sotalia fluviatilis) in south-eastern Brazil

Journal of the Marine Biological Association of the United Kingdom, 2003
This study reports the age estimation of marine tucuxi dolphins (Sotalia fluviatilis) found dead along the south-east coast of Brazil (24°40′S–25°30′S). The investigated specimens were collected from August 1995 to December 1998. Ages were estimated through the number of Growth Layer Groups (GLGs) from decalcified and stained thin sections of teeth.

Selective Heating of Vibrissal Follicles In Seals (Phoca Vitulina) and Dolphins (Sotalia Fluviatilis Guianensis)

Journal of Experimental Biology, 2000
ABSTRACT The thermal characteristics of the mystacial vibrissae of harbour seals (Phoca vitulina) and of the follicle crypts on the rostrum of the dolphin Sotalia fluviatilis guianensis were measured using an infrared imaging system. Thermograms demonstrate that, in both species, single vibrissal follicles are clearly defined units of ...

Concentrations of heavy metals in Sotalia fluviatilis (Cetacea: Delphinidae) off the coast of Ceará, northeast Brazil

Environmental Pollution, 2003
Lead (Pb), cadmium (Cd) and mercury (Hg) concentrations on liver and kidney of Sotalia fluviatilis (Cetacea: Delphinidae) stranded in the coast of Ceará, Brazil, were studied from 1996 to 1999. Pb levels were usually lower than the detection limit (0.1 microg/g).
