At almost every zoo I’ve visited, there’s a crowd around the naked mole rat (Heterocephalus glaber) display. For some reason, we find those ugly little rodents to be fascinating creatures. Kids will watch them scurry around transparent burrows longer than they’ll watch the lions. But even if you’ve been one of those fans, I’ll bet there’s plenty you still don’t know, so here are 14 fun facts:

1 ) Despite their names, naked mole rats are neither moles nor rats (nor are they totally hairless). They are more closely related to porcupines and guinea pigs.
2 ) Naked mole rats live in the horn of Africa and are native to Somalia, Ethiopia and Kenya.
3 ) They are one of only two mammal species that are eusocial. Eusociality, a type of social organization in which individuals live in a hierarchy, is more familiarly found in insects like ants and wasps. There is a queen mole rat, soldiers and workers. (The other eusocial mammal species is another type of mole rat.)
4 ) Soldier mole rats defend the colony from both predators—mostly snakes—and foreign mole rats, which they identify as foreign by their odor.
5 ) Worker mole rats are celibate and spend most of their time digging.
6 ) The queen isn’t born a queen. She’s a female who has fought her way to the top.
7 ) Naked mole rats live almost their entire lives in darkness underground, which is why zoo displays keep them under dim, red lights.
8 ) A colony of naked mole rats can consist of 20 to 300 individuals. Their underground territory can be as large as six football fields.
9 ) The burrow has rooms for specific purposes, such as nesting, raising young, eating and, um, waste disposal.
10 ) They’re not blind. However, their eyes are very small and naked mole rats will often close them when they run through the tunnels.
11 ) A mole rat’s incisors can be moved independently of each other and even work together like a pair of chopsticks.
12 ) They are the longest-lived rodents, with a lifespan of up to 30 years.
13 ) No one has ever found cancer in naked mole rats; they appear to be resistant to the disease.
14) Scientists recently sequenced the genome of the naked mole rat, hoping to find the secret to its long life and disease resistance.

Been dying to have a pet tarantula but ikienda Mia hakuna kurara till you find it. Here are some fun facts




There are approximately 900 species of tarantula in the family Theraphosidae.
The tarantula’s reputation is based more on legend than reality as there are only a few species which have a powerful bite. The venom of most is not highly toxic to humans. Tarantulas are actually placid and harmless and will only attack if goaded and, in many cases, the bite is no more harmful to humans than a bee sting.
Tarantula’s jaws move up and down, instead of the more common side-to-side motion in other spiders. They also have 8 tiny eyes, which are able to distinguish the slightest movement, and hairs which cover its body and are extremely sensitive to vibrations.
Some species have adhesive ‘hair-brushes’ on the tip of their legs which allows them to climb vertically up even the smoothest leaves.
Tree-dwelling species locate a mate by their scent, and then follow the silken trail that the female leaves as she moves.
While mating takes place at various times of the year, rainstorms in the desert areas of south-western Mexico causes vast number of male spiders to wander around in search of a potential mate. In some species, the male performs a jerky courtship dance to encourage the female to become receptive.
After mating, the female carries her eggs in a silken cocoon attached to her body. The growth of a newly hatched spider into a mature spider is a long process and can take up to ten years.
The tarantula does not spin a web, but bites its prey with long, curved fangs, injecting it with a poison which slowly renders the victim helpless. It will then crush its food between its powerful jaws, at the same time injecting a fluid which breaks down the victim’s tissues. This turns the prey into a soft pulp, which can then be eaten.

Tarantulas have a wide range of defences. Some species simply lean back on their haunches, raising their head and legs and exposing their curved fangs in an intimidating display. South American species of tarantula use their legs to scrape off the fine hairs from the top of their abdomen. Each hair is covered with tiny points which, when propelled at an enemy, are both painful and dangerous, especially if they come into contact with the eyes or skin. These tactics are used against a variety of predators, such as racoons and skunks which try to dig the tarantula out of its burrow, or birds, lizards and frogs which may attack it when it is exposed in the open.
The ‘spider-hunting wasp’ is the most deadly enemy of the tarantula. Known as the ‘tarantula hawk’, it is usually much smaller than the tarantula, yet ventures into the spider’s burrow and manages to paralyze it with its sting. It then drags the spider back to its own burrow and keeps it to provide a fresh supply of food for its larvae.
The purse-web spider, Atypus affinis, is a British species once thought to be a tarantula; however it has now been classified separately.
Some of the more popular and colourful species are now threatened due to collecting for the exotic pet trade. The Mexican red-kneed tarantula is a protected species and international trade in this spider is restricted under law.
The name tarantula was originally given to a spider living in Southern Italy from the town of Taranto where legend claims that a small species of spider living there had a fatal bite. The only cure was for the victim to dance until exhausted, by which time the poison would have been sweated from the system (the frenzied folk dance based on the Italian legend is called the tarantella).
