How do you classify a tarantula?

Answer 1

A spider is classified as an arachnid. :D

Answer 2

Australia's described spider fauna consists of about 2000 species, perhaps as little as half of the total spider fauna. Most of these species come from the eastern and southern regions of Australia. Numbers of species are are continually changing due to constant research and new species discoveries.

World-wide, more than 40,000 species of Spiders have been described. To make sense of this diversity scientists recognise taxonomic groups, of which the most natural is the species. Species are separated from each other by differences in the structure of their mating organs (genitalia). Related species share similar genitalic structural patterns.

Related species are classified into groups called genera and related genera into larger groups called families.

Classification of spiders

-Phylum - Arthropoda

-Class - Arachnida

-Order - Araenae

-Suborder Mesothelae - segmented spiders

-Suborder Opisthothelae - includes all other spiders

-Infraorder Mygalomorphae - 'ancient' spiders such as tarantulas, trapdoor and funnel web spiders). Mygalomorph spiders have reduced spinnerets, dagger-like fangs and two pairs of book lungs similar to ancestral ground-living spiders.

-Infraorder Araneomorphae - 'modern' spiders include the vast majority of spiders such as orb weavers, redbacks and huntsman spiders. Araneomorph spiders have pincer-like fangs, most have 6 spinnerets, and one pair of book lungs plus a pair of air tubes (tracheae)

At each of these taxonomic level a unique set of structural identifying features (morphological characters) identifies the particular taxonomic group. Characters may be derived from examination of chromosomal, protein and genomic (DNA, RNA) data. Relationships between groups of species, genera, families, etc. can be studied by examining the distribution of derived characters within the group using cladistic techniques.

Taxonomic keys are used to separate spiders into different families, genera and species. Keys are constructed using key structural features of the spiders. Taxonomic descriptions and revisions, with keys and data on distribution patterns, relationships and Biology, are published in scientific journals.

Answer 3

A tarantula cannot be classified it does not belong to the Amphibian, Mammal, Fish, Bird or Reptile group.

Answer 4

Arachnids
