Paintings of Araneus angulatus from Svenska Spindlar of 1757, the first major work on spider taxonomy. Spider taxonomy is the 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, which has more than 48,500 described species. [1]
The order name Araneae derives from Latin aranea [107] borrowing Ancient Greek ἀράχνη arákhnē from ἀράχνης arákhnēs. [108] Spiders are divided into two suborders, Mesothelae and Opisthothelae, of which the latter contains two infraorders, Mygalomorphae and Araneomorphae.
The extant chelicerates comprise two marine groups: Sea spiders and horseshoe crabs, and the terrestrial arachnids. These have been thought to be related as shown below. [41] [44] (Pycnogonida (sea spiders) may be excluded from the chelicerates, which are then identified as the group labelled "Euchelicerata". [46]) A 2019 analysis nests ...
The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders. [3]
By the Jurassic period, the sophisticated aerial webs of the orb-weaver spiders had already developed to take advantage of the rapidly diversifying groups of insects. A spider web preserved in amber, thought to be 110 million years old, shows evidence of a perfect "orb" web, the most famous, circular kind one thinks of when imagining spider webs.
The American Ornithological Society said it is trying to address years of controversy over a list of bird names that include human names deemed offensive. Around 70 to 80 bird species will be ...
This year has secured some “major nature wins”, from spoonbill breeding success to an impressive comeback for one of the UK’s largest spiders, conservationists said. Other wins for nature in ...
In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct.
