The star-nosed mole (Condylura cristata) is a small mole found in wet low areas of eastern Canada and the northeastern United States, with records extending along the Atlantic coast as far as extreme southeastern Georgia. It is the only member of the tribe Condylurini and the genus Condylura.
The star-nosed mole is easily identified by the 11 pairs of pink fleshy appendages ringing its snout, which is used as a touch organ with more than 25,000 minute sensory receptors, known as Eimer's organs, with which this hamster-sized mole feels its way around. With the help of its Eimer's organs, it may be perfectly poised to detect seismic wave vibrations.The star-nosed mole is covered in thick, blackish-brown, water-repellent fur, and has large, scaled feet and a long, thick tail, which appears to function as a fat storage reserve for the spring breeding season. Adults are 15 to 20 cm (5.9 to 7.9 in) in length, weigh about 55 g (2 oz), and have 44 teeth. The mole's most distinctive feature is a circle of 22 mobile, pink, fleshy tentacles called rays at the end of the snout, from which it derives its name. These are used to identify food by touch, such as worms, insects and crustaceans.
