Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spiders Of New Zealand
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions. The New Zealand spider with the largest leg span is the Nelson cave spider ('' Spelungula cavernicola''), with a leg span of up to and a body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites. The flat huntsman spider ('' Delena cancerides''), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.Rowell and Avilés (1995).

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Celaenia Excavata
''Celaenia excavata'', the bird dropping spider of Australia and New Zealand, derives its name from mimicking bird droppings to avoid predators, mainly birds. However, there are other species of spider that resemble bird droppings, for example species of '' Mastophora'' (a bolas spider). Habitat and appearance The males are much smaller than the females, about 2.5 mm as opposed to 12 mm. The females have up to 13 egg sacs, with about 200 eggs each, strung together with strong threads. Their toxicity is unknown, but may be able to cause mild illness in humans. ''Celaenia excavata'' is found throughout large parts of eastern and southern Australia and have also been recorded in central Australia; they are also seen in suburban gardens. The egg sacs of the bird-dropping spider are large, marbled brown colored spheres, each about 12 mm in diameter and containing over 200 eggs. Up to 13 sacs are silked together in a group, beneath which the spider may be found awaiting pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
