This spider chart represents the allocated budget versus actual spending for a given organization. A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is ...
Spider taxonomy is that part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida with more than 48,500 described species. [1] However, there are likely many species that have escaped the human eye to this day, and many specimens stored in ...
Spiders (order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, [2] and spinnerets that extrude silk. [3] They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. [4][5] Spiders are found worldwide on every continent ...
External anatomy. The underside and head of a female spider. Spiders, unlike insects, have only two main body parts (tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). The exception to this rule are the assassin spiders in the family Archaeidae, whose cephalothorax ...
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
Argiope bruennichii. Argiope bruennichi, commonly known as the wasp spider, is a species of orb-weaver spider found across Central and Northern Europe, several regions of Asia, plus parts of the Middle east, North Africa and the Azores. [1][2] Like many other members of the same genus Argiope, this species features distinctive yellow, white and ...
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History.
The Goliath birdeater (Theraphosa blondi) belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass (175 g (6.2 oz)) and body length (up to 13 cm (5.1 in)), and second to the giant huntsman spider by leg span. [1] It is also called the Goliath tarantula or Goliath bird-eating ...
