Star-nosed moles
What are star-nosed moles? The star-nosed mole, Condylura cristata, is one of about 30 species of mole in the mammalian order Insectivora. Although they are rarely seen, they are relatively common in the wetlands of eastern North America and Canada. They weigh about 30–50 grams and have large clawed forelimbs for digging their extensive underground burrows. Like most other moles, they give birt...
متن کاملBody oxygen stores, aerobic dive limits and diving behaviour of the star-nosed mole (Condylura cristata) and comparisons with non-aquatic talpids.
The dive performance, oxygen storage capacity and partitioning of body oxygen reserves of one of the world's smallest mammalian divers, the star-nosed mole Condylura cristata, were investigated. On the basis of 722 voluntary dives recorded from 18 captive star-nosed moles, the mean dive duration (9.2+/-0.2 s; mean +/- S.E.M.) and maximum recorded dive time (47 s) of this insectivore were compar...
متن کاملThe sense of touch in the star-nosed mole: from mechanoreceptors to the brain.
Star-nosed moles are somatosensory specialists that explore their environment with 22 appendages that ring their nostrils. The appendages are covered with sensory domes called Eimer's organs. Each organ is associated with a Merkel cell-neurite complex, a lamellated corpuscle, and a series of 5-10 free nerve endings that form a circle of terminal swellings. Anatomy and electrophysiological recor...
متن کاملAtypical moles.
Atypical moles can be distinguished visually by clinical features of size greater than 6 mm in diameter, color variegation, indistinct borders, and textured surface. All patients who have atypical moles should be counselled about sun avoidance, screening of family members, and regular skin checks at least once per year. Total body photography and dermoscopy can aid in regular skin monitoring fo...
متن کاملThe Star-Nosed Mole Reveals Clues to the Molecular Basis of Mammalian Touch
Little is known about the molecular mechanisms underlying mammalian touch transduction. To identify novel candidate transducers, we examined the molecular and cellular basis of touch in one of the most sensitive tactile organs in the animal kingdom, the star of the star-nosed mole. Our findings demonstrate that the trigeminal ganglia innervating the star are enriched in tactile-sensitive neuron...
