From Wikipedia, the free encyclopedia

Mud plume feeding (or mud ring fishing) is a cooperative feeding behavior seen in bottlenose dolphins on the lower coast of Florida.[1] Dolphins use this hunting technique to forage and trap fish. A single dolphin will swim in a circle around a group of fish, swiftly moving his tail along the sand to create a plume[2]. This creates a temporary net around the fish and they become disoriented. The fish begin jumping above the surface, so the dolphins can lunge through the plume and catch the fish.

Strategy[edit]

  1. Single dolphin in the group will begin to swim with his tail moving along the sand; initial appearance of suspended sediment will appear
  2. As the dolphin moves in a circle, the plume begins to grow
  3. Cessation of plume growth and repositioning of dolphin in orientation to the plume
  4. Dolphin lunges through the plume into the group of trapped fish
