The blind river dolphin (Platanista gangetica), first written about by Pliny the Elder in A.D. 72, was found (10 November 1968) to be the first known side-swimming cetacean. The rudimentary eye lacks the lens, but anatomical evidence suggests that the eye may serve as a light sensor. The underwater sound emissions of this species, although similar to those of the Amazon River dolphin (Inia geoffrensis), appear to be produced constantly. 
The anatomy of the eye of the Ganges River Dolphin Platanista gangetica (Roxburgh, 1801)
In the scientific and populär literature about vision or about cetaceans, the "blind" River Dolphin is a favourite subject, being frequently mentioned as the only known aquatic mammal with degenerate
Ex situ options for cetacean conservation
China’s Yangtze river dolphin (Lipotes vexillifer), was declared likely to be extinct in 2006, due to threats in the wild such as habitat loss, entanglement in fishing gear and ship strikes, which
Adaptiveness and Ecology of Echolocation in Toothed Whales
Of all aquatic animals only odontocete cetaceans are known to have a well developed sonar system, and this review is primarily concerned with the toothed whales.
Behavioural laterality in foraging bottlenose dolphins (Tursiops truncatus)
A significant right-side (left turn) bias in bottlenose dolphins off Bimini, The Bahamas is reported, which is hypothesized to be due in part to the possible laterization of echolocation production mechanisms, the dolphins' use of the right set of phonic lips to produce eCholocation clicks, and a right eye (left hemisphere) advantage in visual discrimination and visuospatial processing.
Hyper-longirostry and kinematic disparity in extinct toothed whales
The results show that the extremely long rostra of extinct toothed whales vary considerably in functionally relevant measures of shape and likely exhibited a diversity of feeding behaviors, ranging from those similar to modern odontocetes to those convergent with billfish.
Conservation ecology and phylogenetics of the Indus River dolphin (Platanista gangetica minor)
The historical range of the Indus River dolphin has declined by 80% since the 19th century and has been fragmented into 17 river sections by construction of irrigation barrages. Dolphin sighting and
Joint attention and echoic eavesdropping in wild bottlenose dolphins (Tursiops aduncus)
This thesis aims to determine if wild Indo-Pacific bottlenose dolphins engage in behaviors predicted to follow directly from the 'echoic eavesdropping' hypothesis in a natural setting, and to explore how these behaviors are related to a discussion of joint attention in dolphins.

Ganges River Dolphin: An Overview of Biology, Ecology, and Conservation Status in India
This article reviews current status of the sub-species, habitat use, and the potential threats that the dolphins face for their survival and recommends strategies for the conservation of this Endangered and endemic sub- species.
Auditory Thresholds of a Fresh Water Dolphin, Inia geoffrensis Blainville
A fresh water Amazon River dolphin, Inia geoffrensis, was conditioned to respond to pure tones by pushing a response lever. By using this method an audiogram was obtained for frequencies between 1.0
