Magnetoreception
Videos
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
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.
Ampullae of Lorenzini

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

…eukaryotes. Cartilaginous fish including sharks and stingrays can detect small variations in electric potential with their electroreceptive organs, the ampullae of Lorenzini. These appear to be able to detect magnetic fields by induction. There is some evidence that these fish use magnetic fields in navigation. Biologists…
