Ampullae of Lorenzini
Videos
Ampullae of Lorenzini are electroreceptors, sense organs able to detect electric fields. They form a network of mucus-filled pores in the skin of cartilaginous fish and of basal bony fishes such as re

Magnetoreception

Magnetoreception is a sense which allows an organism to detect the Earth's magnetic field. Animals with this sense include some arthropods, molluscs, and vertebrates. The sense is mainly used for orie

…of their body. Ampullae of Lorenzini also contribute to the ability to receive geomagnetic information. As magnetic and electrical fields are related, magnetoreception via electromagnetic induction in the ampullae of Lorenzini is possible. A study from 2004 shows this magnetoreception by cartilaginous fish as they…
Experiments on European robins, which are migratory, suggest their magnetic sense makes use of the quantum radical pair mechanism.
The yellow stingray is able to sense the intensity and inclination angle of a magnetic field.
Magnetoreception plays a part in guiding loggerhead hatchlings to the sea.
The Zambian mole-rat is one of several mammals that use magnetic fields, in their case for nest orientation.
