Naked Mole Rats (Heterocephalus glaber), a.k.a the sand puppy, a.k.a. the desert mole rat, are more than meets the eye– even given that what meets the eye is just about everything. Among the many interesting facts about mole-rats is that while long belived to be blind, they are in fact merely myopic; having adapted to their mostly-lightless environment, they use the sudden incursion of brilliant light into their subterranean burrows as an early-warning sign for approaching predators.
Another unique characteristic of the naked mole rat is that it is effectively cold-blooded, making it an oddity amongst mammals. Still more oddly, the Naked mole rat is one of only two mammalian species to live eusocially, in complex social structures containing only one female (the queen) and between one and several males responsible for reproduction, while the rest of the colony functions as workers.*
However, the oddest attribute of the naked mole rat is, indisputably, it’s uncanny resemblance to naked old man penis (see figure B., below).
