Monotremes and Electroreception

Abstract

Through their evolution, monotremes have developed several characteristics that make them unique from most other mammals.

The bill of the platypus, Ornithorhynchus anatinus, and the beaks of the echidnas, Tachyglossus aculeatus and Zaglossus bruijni, all contain three types of receptors: push-rod mechanoreceptors, serous gland electroreceptors, and mucous gland electroreceptors. The information collected by these receptors is sent to the somatosensory cortex. The platypus, whose electroreceptive system is more complex than that of the echidna, uses electroreception to capture prey and is the only mammal know to so. (It is not yet known if the echidna uses electroreception to capture prey.)
