According to Moller, the rays do not use vision for hunting in this mode, but rely on pressure and electroreception alone. |
I think they've demonstrated in a convincing way that this dolphin species can use electroreception, and in a way that's sensitive enough to potentially detect prey. |
In addition, electroreception, the ability to detect minute electrical activities, works effectively at short distances in sharks. |
Muscle contractions also produce little surges of electrical activity that a shark can detect using electroreception. |
At least one species, the tucuxi or Guiana dolphin, is able to use electroreception to sense prey. |
It is the electroreception system that allows them to navigate through the muddy dark waters they dwell in. |
