Pełniejszy materiał źródłowy / excerpt

The star-nosed mole (Condylura cristata) is a small semiaquatic mole found in moist, low elevation areas in the northeastern parts of North America. It is the only extant member of the tribe Condylurini and genus Condylura. It has more than 25,000 minute sensory receptors in touch organs, 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 nose is about 1.5 cm (0.59 in) in diameter with its Eimer's organs distributed on 22 appendages. Eimer's organs were first described in the European mole in 1872 by German zoologist Theodor Eimer. Other mole species also possess Eimer's organs, though they are not as specialized or numerous as in the star-nosed mole. Because the star-nosed mole is functionally blind, the snout was long suspected to be used to detect electrical activity in prey animals, though little, if any, empirical support has been found for this hypothesis. The nasal star and dentition of this species appear to be primarily adapted to exploit extremely small prey. A report in the journal Nature gives this animal the title of fastest-eating mammal, taking as little as 120 milliseconds (average: 227 ms) to identify and consume individual food items. Its brain decides in approximately eight milliseconds if prey is edible or not. This speed is…

Evolution of brains and behavior for optimal foraging: a tale of two predators.. Star-nosed moles and tentacled snakes have exceptional mechanosensory systems that illustrate a number of general features of nervous system organization and evolution. Star-nosed moles use the star for active touch--rapidly scanning the environment with the nasal rays. The star has the densest concentration of mechanoreceptors described for any mammal, with a central tactile fovea magnified in anatomically visible neocortical modules. The somatosensory system parallels visual system organization, illustrating general features of high-resolution sensory representations. Star-nosed moles are the fastest mammalia…

Life is a British nature documentary series created and produced as a co-production between the BBC Natural History Unit, Discovery Channel and Skai tv in association with The Open University. It was first broadcast as part of the BBC's Darwin Season on BBC One and BBC HD from October to December 2009 and was written and narrated by David Attenborough. The series takes a global view of the specialised strategies and extreme behaviour that living things have developed in order to survive; what Charles Darwin termed "the struggle for existence". Four years in the making, the series was shot entirely in high definition. Life premiered on 12 October 2009 in the United Kingdom consisting of ten…
