Electromagnetic sensing ability found in manyrndifferent vertebrates and invertebrates is largely mediated through the opioidrnreceptors and internal opioid peptides. This sensing ability has been shown tornbe light dependent, and therefore also likely dependent on a photoreceptor.rnMost of the research done in invertebrates has been conducted using ​Cepaearnnemoralis​ (the land snail), but none has been done using shell­lessrngastropods or slugs. We tested the effect of two different wavelengths of lightrn(red light­ 650nm and blue light ­ 450nm) on the electromagnetic sensingrnabilities in the Arion Distinctus​ (aka the garden slug). ​Thisrnexperiment was performed by injecting the slugs with an enkephalinase inhibitor,rnfollowed by a 15min exposure to a ±60μT magnetic field in the presence ofrneither red light, blue light, or white light. This experiment demonstrated forrnthe first time that an electromagnetic sensing ability is present in the ​Arionrndistinctus and is light sensitive. ​ Blue light was the most effectivernlight setting for slugs to sense an electromagnetic field.
