What do japanese sea catfish whiskers detect? It’s enough for the Japanese sea catfish. Like all catfishes, this species has long whiskers or barbels sticking out of its face. They house tastebuds that allow the animal to detect chemicals in the water around it. But John Caprio from Louisiana State University has discovered that the barbels are also pH meters.
What are the whiskers on catfish for? Catfish have up to eight “barbels” (whisker-like appendages) located on the chin or sides of the mouth. The barbels’ function is to detect food.
How do catfish detect prey? Catfish are equipped with sensors that can locate prey by detecting slight changes in the water’s pH level, researchers have discovered. The study was an offshoot of work initiated in 1984 when researchers began a collaborative investigation examining the physiology of the taste system of the Japanese sea catfish.

What is sensed by Pacinian corpuscles?
Pacinian corpuscles are rapidly adapting (phasic) receptors that detect gross pressure changes and vibrations in the skin. Any deformation in the corpuscle causes action potentials to be generated by opening pressure-sensitive sodium ion channels in the axon membrane.
Can Kardia detect heart attack?
Kardia can detect atrial fibrillation. In fact, it is only FDA-cleared to identify AF, tachycardia (increased heart rate) and bradycardia (low heart rate). It’s important to know that it’s not for diagnosing heart attacks or other diseases.
