Stingray jaws strut their stuff
Article Abstract:
Cartilage is less dense than bones helping chondrichtyan fishes to maintain near neutral buoyancy. Some stingrays often use their cartilaginous jaws to crush hard prey. The cownose ray Rhinoptera bonasus has been studied to determine how cartilaginous jaws are used to crush hard-shelled prey. Organized, mineralized structures were found that serve a distinct biomechanical role in the core of a mature cartilaginous tissue.

Caught in the crossflow
Article Abstract:
Some fish species have been found to use crossflow filtration to remove small food items from the water. With cross filtration, food particles stay in suspension instead of adhering to the gill rakers. This research has not been able to identify exactly how crossflow filtration in fishes functions.

Crossflow filtration in suspension-feeding fishes
Article Abstract:
The rakers of three distantly related species of suspension-feeding fishes have been found to function as a crossflow filter. It was established that the high-velocity crossflow along the rakers carriers particles away from the raker surfaces and moves the particles towards the oesophagus.
