	Tucuxi
		The Tucuxi (Sotalia fluviatilis) is a dolphin found both in the rivers of the Amazon Basin and the in the coastal waters to the north and east of South America.
		The riverine Tucuxi exists along much the length of the Amazon River and many of its tribuitaries, and is found in Peru, south-east Columbia, eastern Ecuador.
		Tucuxis are quite active and may jump clear of the water, somersault, spy-hop or tail-splash.

	Tucuxi - Wikipedia, the free encyclopedia
		The beak is well-defined and of moderate length.
		The riverine Tucuxi exists along much the length of the Amazon River and many of its tributaries, and is found in Peru, south-east Colombia, eastern Ecuador.
		Tucuxis are quite active and may jump clear of the water (a behavior known as Breaching), somersault, spy-hop or tail-splash.

	Scientific Documentation Page
		The body of the tucuxi is similar to that of the bottlenose except that tucuxi have a slightly longer, more prominent beak, less clearly demarcated from the forehead than the bottlenose, and the body of the tucuxi as a whole, is stubbier (Leatherwood, 1983).
		Tucuxi are smaller than bottlenose, with a maximum length of 1.8 m, as compared to the maximum length of a bottlenose of 3.9 m (Carwardine, 1995).
		Tucuxi were identified by their more triangular shaped dorsal fin, smaller body size, and body coloration consisting of a dark gray back turning to pinkish-white on the belly.

	CMS: Sotalia fluviatilis, Tucuxi
		The appearance of the tucuxi resembles that of a smaller bottlenose dolphin.
		The tucuxi is light grey to blueish-grey, on the back and pinkish to light grey on the belly, with a distinct boundary between the mouth gape and the flipper's leading edge.
		The tucuxi is present in rivers of the Amazon region that cross territories of such countries as Brazil, Colombia, Ecuador and Peru.

	Tucuxi, Cananéia estuary, Brazil (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-09-10)
		The marine tucuxi dolphin, Sotalia guianensis (Ván Benéden, 1864), is one of the lesser-studied delphinids.
		Tucuxis can be found year-round throughout the Cananéia estuary and the area represents important breeding and calving grounds for this species.
		Photographs from individual tucuxis are preferably taken from both the left and right side as sometimes their unique notches and scratches on their dorsal fins are not always easily recognised.

	All About Dolphins
		The Sotalia, or tucuxi, is also found in the Amazon and Orinoco basins but is not as widely distributed as the boto.
		The boto and tucuxi are cetaceans and belong to the same scientific Suborder, the Odontoceti because they have teeth.
		The tucuxi's neck vertebrae are fused so they aren't as flexible as the boto and cannot maneuver between the flooded forest floor.

	Sarasota Dolphin Research Program
		The marine tucuxi (Sotalia fluviatilis) is one of the lesser-known delphinids.
		In Colombia, Tucuxi have been cataloged as a “vulnerable” species due to loss of habitat, deforestation, pollution, and incidental mortality in local fisheries and direct takes for use as shark bait or to be sold on the fl market.
		Tucuxi is one of the top predator species along the Caribbean coast of Colombia.

		Until this time, tucuxi dolphins were not known to exist as far north as Costa Rica.
		Tucuxi (pronounced "too koo shee") are a little-studied species of dolphins found in fresh water of rivers, estuaries and adjacent coastal areas of South America, and, until this, as far north as Panama.
		A scientific article describing the interspecies interactions between the tucuxi and bottlenose has been submitted to a Marine Mammal journal for publication, and will soon be made available to the public.

	CSI Whales Alive! Vol. X No. 2 Tucuxi Marine Dolphins
		The marine tucuxi dolphin or gray dolphin, Sotalia fluviatilis, is endemic along the tropical and subtropical Atlantic coastlines of South and Central America and is perhaps the cetacean most affected by human activities, mainly incidental captures in Brazil, after the franciscana, Pontoporia blainvillei.
		With the support of Cetacean Society International, the Dolphins Project ("Projeto Golfinhos") was begun in October 2000, a study with marine tucuxi dolphin that inhabits the Paraty Bay (23° 13'S 44° 42'W; 23° 02'S 44° 35'W) region on the south of Rio de Janeiro State, Brazil.
		The Marine Tucuxi Dolphin Area of Environmental Protection of Paraty Bay will be proposed by the Dolphins Project in 2002 to the Municipal Town Hall of Paraty.

	Sotalia fluviatilis, Tucuxi at MarineBio.org
		The Tucuxi (pronounced too-koo-shi), Sotalia fluviatilis (Gervais and Deville, 1853), (aka Gray dolphin and Gray river dolphin), resembles a Bottlenose dolphin except that it is slightly smaller in size.
		The marine Tucuxi reaches 2.1-2.2 m in length, and the riverine Tucuxi reaches 1.5 m in length.
		In one study, 938 Tucuxis were taken in drift nets from the port of Arapiranga during the summer of 1996 followed by another 125 during the winter.

	baiji.org foundation — Tucuxi
		There are two morphologically distinct forms, the freshwater tucuxi and the marine tucuxi, the former being distinctly smaller in size.
		However, there is concern over the tucuxi, particularly due to the high numbers caught and killed by gillnets in the lower reaches of the Amazon.
		The freshwater tucuxi are exclusively a freshwater species that inhabit rivers and lakes but not in flooded forest and avoids rapids.

	IUCN Red List of Threatened Species: Sotalia fluviatilis
		Tucuxis are generally not hunted, but they are extremely vulnerable to capture in gillnets.
		The genital organs and eyes of Tucuxis are sometimes sold as amulets, and their meat and blubber are eaten or used as shark bait.
		The Tucuxi's freshwater and near-shore marine distribution means that it is vulnerable to the effects of water development projects, chemical pollution, and noise, as well as bycatch.

		The Tucuxi are very adaptable dolphins, some living 2,500 kilometers up the murky fresh water of the Amazon River, some in clear coastal sea waters from Panama to Southern Brazil, and others in the polluted estuaries and rivers along eastern Central and South America.
		It's thought that their babies are usually born after a ten-month gestation, during the low water season, probably because fish are more concentrated in shallow pools and easier to hunt.
		As the previously unknown Tucuxi accept the presence of careful researchers we will learn much more about their lives and societies.

	Lago Preto - dolphins
		In the collection of behavioural and ecological data, populations of boto (Inia geoffrensis) and tucuxi (Sotalia fluviatillis) were studied during the month of July 2001, on the Rio Yavari of Peru.
		Boto and tucuxi were surveyed from a research boat, from aboard aluminium/wooden canoes equipped with outboard motors, from vantage points on the Peruvian shoreline and from elevated positions aboard an anchored research boat.
		It is hoped that these findings will contribute to the overall understanding of boto and tucuxi and aid in future studies of the two species in the Upper Amazon region of the Rio Yavari.

		It may be the last place to look for sick cattle, but animal health experts in Brazil have taken to the waters of the mighty Amazon to fight one of the region's age-old foes: foot-and-mouth disease.
		The Tucuxi ("River Dolphin") has been sailing the lower Amazon and its tributaries to spread the word among locals about what needs to be done to eliminate febre aftosa, or foot-and-mouth disease, from their region by the end of 2009.
		The Tucuxi is a pilot project that forms part of "Brazil Free from Foot-and-Mouth," a plan launched by Brazil's Ministry of Food and Agriculture late last year to promote vaccination and raise awareness of the connection between improving animal sanitation, eradicating the disease and generating local employment and income.

		Allison is one of 13 students selected to travel with Dr. Paul Forestell, Associate Professor for Psychobiology at Southampton College, to Manzanillo to participate in the study and to document the social behaviors of a group of tucuxi dolphins found off the east coast of Costa Rica.
		This will be Allison's third trip to the Talamanca Dolphin Foundation with Dr. Forestell to conduct research on the tucuxi and bottlenose dolphins in order to build upon previous data and learn more about the behaviors of the local dolphins.
		There is now increasing concern that ongoing attempts to observe the tucuxi may result in high levels of disturbance, and interfere with their use of what appears to be critical habitat.

		Forestell led the group in an ongoing study of the unusual observation of inter-species mating between the ubiquitous bottlenose dolphin (Tursiops truncatus) and the little known tucuxi dolphin (Sotalia fluviatilis), two species found along the coastal area of the Gandoca Wildlife Reserve in Costa Rica.
		The project is showing that a small sub-set of bottlenose dolphins, working in coalitions of two or three animals, move reproductively active female tucuxi away from their groups, and attempt to mate with them.
		The tucuxi engage in avoidance behaviors and male tucuxi display aggressive behaviors toward the bottlenose when they approach.

		In other areas of their range, especially in Brazil where habitat degradation due to gold mining is a greater problem for the dolphins than in Pacaya Samiria, populations of both Bufeo and Tucuxi are threatened.
		Buto inhabit more diverse habitat than Tucuxi and genetic evidence indicates that they have inhabited the Amazonian basin for much longer.
		Tucuxi and Buto both are common in the large and smaller rivers of the area, but only Buto appear to enter the flooded forest during high water.
