Tailless Tenrec

Tenrec ecaudatus
Today's animal is native to Madagascar, and has been introduced to the Mascarene Islands. But happily, unlike some of the other critters we've talked about this week, the Tailless Tenrec is not on the verge of extinction! These interesting little mammals actually have a stable population, no major threats, and a wide range.

So now that we've got conservation status out of the way, what on Earth is a Tenrec?! The answer is... interesting. Tenrecs are members of that weird African Superorder known as Afrotheria. Their hodgepodge of relatives includes Elephants, Manatees, Hyraxes, Aardvarks, and Sengi. Tenrecs themselves look a bit like shrews or opossums, and some species even resemble Hedgehogs. This is due to convergent evolution-- Tenrecs evolved to fill the ecological niches that were normally filled by the aforementioned creatures. They May look alike and act alike, but they aren't actually related!

The Tailless Tenrec is the largest of the land-dwelling Tenrecs. They actually do have tails, despite the name, though the tails are very, very short. They look a bit like a Shrew crossed with a Hedgehog, and the younger Tenrecs even have spines to protect them while they grow up (adults have long, coarse hairs).

The Tailless Tenrec is one of the largest insectivores in the world. They detect prey with their long whiskers (they are nocturnal), and capture it with their mouths. Aside from insects, they do also feed on small vertebrates and plants.

You will only really see these Tenrecs in groups during a  few times each year-- during the breeding season when males attract mates, and after the young are born when females are taking care of their offspring. They are very solitary otherwise. Tailless Tenrecs can have massive litter sizes-- up to 32! The young are helpless for the first week or so, but they grow fast and will be on their own after about 5 weeks. They reach sexual maturity around 6 months of age.

Tailless Tenrecs communicate in a number of different ways. When threatened, the ridge of hair on their back rises up. They also hiss, squeal, and even scream!

    Hello! My is E.M. Schwab. I have a blog called 100 most Unknown Animals (www.unknownanimals.blogspot.com) and i was wondering if you have any suggestions for any unknown animals. Also if you would be able to promote my site, I will happily do the same for you,

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a...

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills. IUCN Status :  Not Listed ...

Four!

For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!
