Mud ring feeding (or mud plume fishing) is a cooperative feeding behavior seen in bottlenose dolphins on the lower Atlantic coast of Florida, United States and guiana dolphins, on the Estuarine-Lagoon Complex of Cananéia, south São Paulo State, southeastern Brazil. [1] Dolphins use this hunting technique to forage and trap fish.
The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. [3] Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is one of three species of bottlenose dolphin in the genus Tursiops.The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it receives in human care in marine parks and dolphinariums, and in movies and television programs.

Bottlenose dolphins and California sea lions are the main animals used, and are kept at the base in San Diego. Dolphins have powerful biological sonar, unmatched by artificial sonar technology in detecting objects in the water column and on the sea floor. Sea lions lack this, but have very sensitive underwater directional hearing and ...
