STOCK DEFINITION AND GEOGRAPHIC RANGE The coastal morphotype of common bottlenose dolphins is continuously distributed along the Atlantic coast south of Long Island, New York, to the Florida peninsula, including inshore waters of the bays, sounds and estuaries. Several lines of evidence support a distinction between dolphins inhabiting coastal waters near the shore and those present in the insh...

A young man employed at the local aquarium was bitten by a bottlenose dolphin (Tursiops truncatus) during a training session, receiving a slight injury which healed rapidly. Some two months later fluctuant swellings appeared in the region of the bite, which developed into indolent ulcers which have not completely healed seven months after the original bite. Cultures taken on two occasions have ...

A new species of the genus Sinocaulus Fairmaire, 1878, S. truncatus sp. nov., is described from Guizhou, China. Based on the strongly protuberant eyes, the new species is similar to S. omiensis Jin, Ślipiński & Pang, 2013 from Sichuan, but differs from that species in the truncate phallobase of the aedeagus and ventral lobes slightly shorter than dorsal lobe. Distributional data and a key to al...

Along the East African coast, marine top predators are facing an increasing number of anthropogenic threats which requires the implementation of effective and urgent conservation measures to protect essential habitats. Understanding the role that habitat features play on the marine top predator' distribution and abundance is a crucial step to evaluate the suitability of an existing Marine Prote...

The semiwild beach-feeding bottlenose dolphins (Tursiops adunrus) of Monkey Mia, Western Australia, provide an unparalleled opportunity to examine prey preference of this species. In a series of binary-choice feeding experiments, we took advantage of the animals’ willingness to be fed by hand, to explore their preferences for fish species, size, and state (freshly caught or previously frozen). ...

An unusual number of near term and neonatal bottlenose dolphin (Tursiops truncatus) mortalities occurred in the northern Gulf of Mexico (nGOM) in 2011, during the first calving season after two well documented environmental perturbations; sustained cold weather in 2010 and the Deepwater Horizon oil spill (DWHOS). Preceding the stranding event, large volumes of cold freshwater entered the nGOM d...

Bottlenose dolphins (Tursiops truncatus) use the frequency contour of whistles produced by conspecifics for individual recognition. Here we tested a bottlenose dolphin's (Tursiops truncatus) ability to recognize frequency modulated whistle-like sounds using a three alternative matching-to-sample paradigm. The dolphin was first trained to select a specific object (object A) in response to a spec...

In recent years a number of experiments and measurements associated mainly with the Atlantic bottlenose dolphin (Tursiops truncatus) and one with the harbor porpoise (Phocoena phocoena) have shed some interesting light on biosonar signal production and propagation in the head of the animals and the formation of the biosonar beam. In this short review, the results of these experiments will be ta...
