Tailless tenrec, Pyreras Reserve, Madagascar
Another Madagascar-only category: Tenrecs. Tenrecs visually somewhat resemble a hedgehog yet are not closely related. All 31 Tenrec species are believed to descend from a single ancestor that rafted from mainland Africa to Madagascar some 29-37 millions of years ago.
Some unique characteristics of Tenrecs:
- Low body temperature for a mammal, so no scrotum needed to cool sperm
- The anus and urogenital tracts share a single opening, very unusual for a mammal
- They can't see much yet compensate with other keen senses, especially their whiskers are sensitive
- Female carry as many as 32 young and have 29 teats, more than any other mammal
- They can hibernate uninterrupted for 9 months, longer than any other tropical mammal
Diversity within the Tenrec group is enormous. This particular one, the Tailless tenrec, does have a tail yet it is very short. It is the largest of Tenrec species and very spikey, even the face is covered with sharp spikes.
