Knowra Ram feeding Ram feeding Ram feeding is a strategy in which an animal captures prey by moving through it with its mouth open. It occurs in aquatic predators that engulf prey along their path.
Suction feeding : A feeding strategy that draws prey into an animal's mouth by rapidly expanding the mouth cavity. Unlike ram feeding, it relies on inward water flow rather than simply overtaking prey.
Baleen whale : A cetacean that filters small prey from seawater using baleen plates instead of teeth. Some baleen whales engulf large volumes of prey-filled water while swimming forward.
Filter feeding : A feeding method that removes small food particles from water or another fluid. Ram feeding can power filtration, but the two terms describe different parts of the process.
Aquatic locomotion : Movement through water by animals using fins, flippers, tails, or other structures. Ram feeding depends on locomotion to bring the mouth into contact with prey.
Hydrodynamic drag : The resistive force exerted by fluid on an object moving through it. An open mouth increases drag, creating a trade-off between prey capture and swimming cost.
Lunge feeding : A feeding behavior in which an animal accelerates into a dense prey patch and engulfs prey-laden water. It is a specialized, high-speed form of ram feeding used by rorqual whales.
Benthic feeding : Feeding on organisms or organic matter found on or within the bottom of a body of water. It targets food at the substrate rather than intercepting prey while moving through open water.
Fish jaw : A movable skeletal structure in fishes used to seize, manipulate, or process food. Jaw size and mobility shape the opening through which prey enters during ram feeding.
Buccal cavity : The space inside the mouth, bounded by the jaws and other oral structures. Its shape and expansion affect how prey and water enter during a feeding strike.
Basking shark : A large filter-feeding shark that swims with its mouth open to collect plankton. Its steady forward swimming carries plankton-rich water through the mouth and gill rakers.
