The behavior of star nosed moles suggests a second function of the sensory tentacles. Star nosed moles frequently submerge all or part of their tentacles in the water before entering the water themselves. During this time, the proboscis scans the underwater environment and extremely quickly (within 200 miliseconds) allows the mole to identify and capture tiny prey. This behavior, along with the density and complexity of the eimer's organs, suggests that the tentacles may also serve not only as touch receptors but also possibly as electroreceptors analogous in function to the receptor pits in the duck billed platypus.
