Tarantulas give some people the creeps because of their large, hairy bodies and legs. But these spiders are harmless to humans (except for a painful bite), and their mild venom is weaker than a typical bee's. Among arachnid enthusiasts, these spiders have become popular pets.  
Tarantulas periodically shed their external skeletons in a process called molting. In the process, they also replace internal organs, such as female genitalia and stomach lining, and even regrow lost appendages.
There are hundreds of tarantula species found in most of the world's tropical, subtropical, and arid regions. They vary in color and behavior according to their specific environments. Generally, however, tarantulas are burrowers that live in the ground.  
Tarantulas are slow and deliberate movers, but accomplished nocturnal predators. Insects are their main prey, but they also target bigger game, including frogs, toads, and mice. The South American bird-eating spider, as it name suggests, is even able to prey upon small birds.  
A tarantula doesn't use a web to ensnare prey, though it may spin a trip wire to signal an alert when something approaches its burrow. 

These spiders grab with their appendages, inject paralyzing venom, and dispatch their unfortunate victims with their fangs. They also secrete digestive enzymes to liquefy their victims' bodies so that they can suck them up through their straw-like mouth openings. After a large meal, the tarantula may not need to eat for a month. Tarantulas have few natural enemies, but parasitic pepsis wasps are a formidable exception. Such a wasp will paralyze a tarantula with its sting and lay its eggs on the spider's body. When the eggs hatch, wasp larvae gorge themselves on the still living tarantula. 

The tarantula's own mating ritual begins when the male spins a web and deposits sperm on its surface. He copulates by using his pedipalps (short, leglike appendages located near the mouth) and then scuttles away if he can—females sometimes eat their mates. Females seal both eggs and sperm in a cocoon and guard it for six to nine weeks, when some 500 to 1,000 tarantulas hatch.


  1. I didn't know spiders come is such shapes and sizes. The good thing is I say in the city and the chances of these venomous spiders taking a lift is just way out of their imagination. I am safe where I am.

  2. Uh I lived in a city area and on a military base, we had brown recluses living in the houses and had to treat for them it depends on where you live. As a child growing up again I lived in a city and we had black widows. So seriously they CAN live in the city. Depends on what state you live in.
