Terrestrial Tarantulas - Hanging out, high and dry.


The term terrestrial can sometimes be somewhat misleading. Many so called "terrestrials" actually construct a small shelter in vegetation or utilize a short tunnel, sometimes that of another animal like a mouse for example. Then again there are some species that really do fit the description of terrestrial. To illustrate, Lasiodora Parahybara is the third largest spider on the planet, with some females weighing as much as a hundred grams. These spiders are content to sit out in the open (like at the base of a tree) and just munch on any foolish passerby. However as previously mentioned many will benefit from a hide and all should be offered one anyway. Typical terrestrial anatomy is that of strong thick legs and a rotund body along with very powerful mandibles. Some species are capable of short spurt pursuit of prey over about 30-40 centimeters. Most of the terrestrial species prey on animals of similar size, power or weight ratio to themselves making them in general a rather robust and hardy group.
Basic CareTank/Cage
: Knowing the size and type of tarantula and its habits are integral  in choosing the tank/cage you will need. MAKE SURE that the tank/cage you select has a secure lid. 
 Water Source: A shallow water dish will need to be provided for your tarantula. If the spider is on the smaller side, or the dish a little deeper, you may want to add a few small rocks to the dish to keep the tarantula from getting submerged and drowning. Sea sponge is another watering alternative but it tends to go moldy. Take care to ensure correct humidity for your species. 
  Long Tweezers: Hardware stores, medical supply stores, or most pet shops or suppliers  that sell invertebrates will be able to provide you with this invaluable tool. Long tweezers keep your fingers out of the way when removing dead prey (or pieces of dead prey). It is also useful in rearranging tank furniture. 
  Wooden Spoon or Paintbrush: Basically, you want something handy to prod or coax a reluctant or angry tarantula out of your way (or into a holding tank). Make sure it has no chemicals on it, only use new paintbrushes and rinse them in warm water before using to remove any lingering trace chemicals.
Terrestrial tarantulas are more concerned with the length and width of the cage than height. The general consensus is that the minimum floor space is 1.5 - 2 times the leg span of the tarantula. The height of the cage should be enough that the spider can flip over onto it's back (for moulting). Many people go the inexpensive route and purchase plastic storage containers (shoe/sweater box) and ventilation holes drilled into them. Aquariums are also popular choices, but you must be careful that the tank is not too high. Terrestrial tarantulas will explore their tank, which includes climbing the sides and the lid to the tank. There is a good chance that the spider could lose it's hold and fall to the cage floor. If the spider is too high off of the ground when it falls, that could spell trouble for the tarantula.
