Mole's Star

Secret of how moles breathe underground revealed". The Telegraph. 20 July 2010. Archived from the original on 23 July 2010 . Retrieved 19 August 2016. Unlike the five-digit structure of hands with thumbs that we’re accustomed to, moles have an additional thumb called the prepollex. It’s conveniently located beside their thumb, giving this animal six digits. The renowned physicist John Archibald Wheeler once suggested, “In any field, find the strangest thing and then explore it.” Certainly it is hard to imagine an animal much stranger than the star-nosed mole, a creature you might picture emerging from a flying saucer to greet a delegation of curious earthlings. Its nose is ringed by 22 fleshy appendages that are usually a blur of motion as the mole explores its environment. Add large clawed forelimbs, and you've got an irresistible biological mystery. How did this creature evolve? What is the star? How does it function, and what is it used for? These are some of the questions that I set out to answer about this unusual mammal. It turns out that the star-nosed mole has more than an interesting face; it also has a remarkably specialized brain that may help answer long-standing questions about the organization and evolution of the mammalian nervous system. Based on the circular organization of the nerve endings and its innervation pattern in Eimer’s organs, Marasco proposed by mapping experiments that nearly all receptors in the star-nosed mole have a preference for a particular direction of applied stimuli. [22] Thus, while one receptor elicits a strong response if compressed in one direction, it may stay "silent" when compressed in another one.

Most humans don’t intentionally set out to kill moles like they would when hunting for sport or fun. Rather, to preserve their gardens, humans will use chemical treatments that can kill moles when exposed. DogsMost of the species have a single breeding season that lasts throughout the spring months. 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.

The family Talpidae contains all the true moles and some of their close relatives. Those species called " shrew moles" represent an intermediate form between the moles and their shrew ancestors, and as such may not be fully described by the article.Hunting, for moles, often requires digging and excavating the ground. These actions are necessary for them to ambush and capture their ground-dwelling prey. Moles can remove insects that many perceive as undesirable, as those are the primary diet of these creatures. In many areas, humans are the biggest threat to mole survival. Homeowners often trap or poison the animals because of the perceived threat to their lawns. And while moles don’t target plant roots like some believe, many people consider their tunnel systems to be a nuisance. Development projects, agriculture, and other habitat changes can also affect mole populations. Conservation
