This lifeform is found in Brazil.

Tarantula Family (Theraphosidae) is found worldwide and contains some of the largest known spiders. The body length of some tropical species measures up to four inches long.

Spiders (Araneae) are a large group of animals usually with eight legs. Most spiders spin webs to catch their prey. There are about 3,000 species of spiders in the United States.

Arachnid (Class Arachnidae) consists of nine to eleven different surviving orders depending upon how one divides the Arachnid class. In total, there are about 60,000 to perhaps 75,000 species grouped in the following eleven orders:

              Order                     Number of Species

  Acarina-Mites and Ticks                    30,000
  Amblypygi-Tailless Whipscorpions               60
  Araneae-Spiders                            35,000
  Palpigrada-Micro Whipscorpions                 50
  Ricinulei or Podogona-Ricinulids               20
  Pseudoscorpionida-False Scorpions           1,000
  Schizomida-Short Tailed Whipscorpions         --
  Scorpionida-Scorpions                       2,000
  Solpugida-Sun Spiders, Windscorpions        1,000
  Phalangida-Daddy Long Legs                  2,200
  Uropygi-Whipscorpions                          70

The old order, Pedipalpida (Whipscorpions), has been divided into the following orders:

        Uropygi (Whipscorpions)
        Ambylypygi (Tailless Whipscorpions
        Schizomida (Short Tailed Whipscorpions))

Jointed Legged Animals (Phylum Arthropoda) make up the largest phylum. There are probably more than one million different species of arthropods known to science. It is also the most successful animal phylum in terms of the total number of living organisms.

Butterflies, beetles, grasshoppers, various insects, spiders, and crabs are well-known arthropods.

The phylum is usually broken into the following five main classes:

   Arachnida:      Spiders and Scorpions
   Crustacea:      Crabs and Crayfish
   Chilopoda:      Centipedes
   Diplopoda:      Millipedes
   Insecta:        Insects

There are several other "rare" classes in the arthropods that should be mentioned. A more formal list is as follows:

   Sub Phylum Chelicerata

     C. Arachnida:      Spiders and scorpions
     C. Pycnogonida:    Sea spiders (500 species)
     C. Merostomata:    Mostly fossil species

   Sub Phylum Mandibulata

     C. Crustacea:      Crabs and crayfish
      
   Myriapod Group

     C. Chilopoda:      Centipedes
     C. Diplopoda:      Millipedes
     C. Pauropoda:      Tiny millipede-like
     C. Symphyla:       Garden centipedes

   Insect Group

     C. Insecta:        Insects

The above list does not include some extinct classes of Arthropods such as the Trilobites.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
