Mole's Star

Product Information

The ermine or stoat lives in some parts of North America, so it shares a habitat with the mole. Stoats make their homes in nests or underground tunnels, but they themselves do not dig. Instead, they’ll invade a mole’s burrow and kill them for mole tunnels. Buzzards Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, [1] reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. Vanderbilt University neuroscientist Kenneth Catania, who has studied star-nosed moles for 20 years, recently turned his research to the study of star-moles as a route to understanding general principles about how human brains process and represent sensory information. He called star-moles "a gold mine for discoveries about brains and behavior in general—and an unending source of surprises". a b c d e Catania, Kenneth C.; Northcutt, R. Glenn; Kaas, Jon H. (1999).

Much of the action occurs underground, beginning with the search for an appropriate mate. Males will travel up to half a mile to look for a female’s burrow. If no existing tunnel is available to connect the respective burrows, then the males may dig entirely new tunnels.

In our visual system it is not only the movements of the eyes and the anatomy of the retina that revolve around the high-resolution fovea; human brains are specialized to process information predominantly from this part of the visual scene.When golden mole species procreate, female moles may birth litters of one to three pups. They don’t breed at any specific time of the year but throughout the year as needed. Moles have been found to tolerate higher levels of carbon dioxide than other mammals, because their blood cells have a special form of hemoglobin that has a higher affinity to oxygen than other forms. In addition, moles use oxygen more effectively by reusing the exhaled air, and can survive in low-oxygen environments such as burrows. [8] Extra thumbs [ edit ] Mole paw

The star-nose is a highly specialized sensory-motor organ shaped by 22 fleshy finger-like appendages, or tendrils, that ring their nostrils and are in constant motion as the mole explores its environment. The star itself is a centimeter across and thus has a diameter slightly smaller than a typical human fingertip. [16] Nevertheless, it is much larger than the nose of other mole species, covering 0.92cm 2 (0.14in 2) per touch compared to 0.11cm 2 (0.02in 2) covered by the noses of other mole species. This structure is divided into a high resolution central fovea region (the central 11th pair of rays) and less sensitive peripheral areas. [17] In this way, the star works as a "tactile eye" where the peripheral rays (1–10 on each side) study the surroundings with erratic saccade-like movements and direct the 11th ray to objects of interest, just like the primate’s foveating eye. [18]Mole conservation is not a chief concern, which is saddening considering that some species have become rare and others endangered. The nose is about 1cm in diameter with its Eimer's organs distributed on 22 appendages. [5] Eimer's organs were first described in the European mole in 1871 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, [6] 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 120milliseconds (average: 227ms) to identify and consume individual food items. [7] Its brain decides in approximately 8ms if prey is edible or not. This speed is at the limit of the speed of neurons. Moles don’t blindly consume earthworms. Instead, they run the worms through their paws to remove as much dirt from the worm as possible.
