Star-nosed moles are nature’s speed-eating champions
Neuroscientist Kenneth Catania reports, "It is also clear from the behavior that the teeth and the star act as an integrated unit — the 11th rays, located directly in front on the teeth, spread apart as the teeth move forward to grasp small food. All rights reserved. The star-nosed mole mates in late winter or early spring, and the female has one litter of typically four or five young in late spring or early summer.
These bubbles are then drawn back into the nostrils , so that odorant molecules in the air bubbles are wafted over the olfactory receptors. The star-nosed mole Condylura cristata is a small mole found in wet low areas in the northern parts of North America. They can smell underwater. The star-shaped nose is a unique organ only found on the star-nosed mole. Free full text available for further reading. This speed makes the star-nosed mole the fastest-eating animal.
Despite the poorly developed eyes, star-nosed moles have an intricate system to detect prey and understand their environment. The differences between both rapid responses rely on the fact that one of them only has a response during the compression phase.

However, instead of having more sensory organs this fovea region uses a different approach in which a skin surface may be more sensitive to mechanoreceptice input; it has more innervation density. It has free terminals and is therefore able to detect pressure and texture with a high sensitivity and at a Random Sustained Discharge.
If these moles come above ground to look for food it is almost always at night. Carnivore vermivore Average lifespan in the wild: Japanese shrew mole U.
Star-nosed mole - Wikipedia
The myelinated fibers innervating the 11 rays were photographed and counted from an enlarged photomontage by Catania and colleagues. As the drosophila fly is to genetics, or the squid giant axon , is to neurobiology,  the star-nosed mole may be the model organism for tactile transduction.
The moles, which are nearly blind, use their tentacles to survey their murky marshland habit. See the Collection. The tentacled nose is a sense organ used to locate prey. From Wikipedia, the free encyclopedia. By Ed Yong. Journal of Comparative Physiology A. Using their shovel-like front paws, they dig tunnels through marshes, providing an underground superhighway for other mammals, including several different species of shrew and weasels, to enjoy.
