Selenocosmia Stirlingi
''Selenocosmia stirlingi'' is a species of tarantula (family Theraphosidae) that is native to the arid regions of Australia. It is sometimes also referred to as a barking spider or whistling spider as this species, like many tarantulas, can stridulate to produce a "hissing" sound when disturbed or threatened. This species is largely fossorial, living in burrows deep underground, however males are sometimes encountered during the breeding season. Taxonomy and naming This species was originally described by Henry R Hogg in 1901. However, early research from 1894 had noted that this species could produce an audible sound. This is likely how the species got the name "the barking spider". ''Selenocosmia stirlingi'' is a member of the Selenocosmiinae subfamily, which is widespread throughout Australia and South-East Asia.

Tarantula
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. 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". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Selenocosmiinae
The ''Selenocosmiinae'' are a subfamily of tarantulas (Mygalomorphae: Theraphosidae) found throughout South-East Asia and Australia. This subfamily is defined by the presence of a lyra on the maxillae and strikers on the chelicerae, allowing these spiders to stridulate and produce a "hissing" sound. However some species within ''Phlogiellus'' may have secondary lost their lyra but retain their strikers. The monophyly of the subfamily has been only tested using genetic data with a handful of genera or species in a few studies. However, these studies found genera that had been previously placed in this subfamily were actual their own separate subfamily (''Poecilotheria'') and that Selenocosmiinae is most closely related to the Indian Thrigmopoeinae. As of 2021, Selenocosmiinae contains 11 genera.

Australian Desert
The deserts of Australia or the Australian deserts cover about , or 18% of the Australian mainland, but about 35% of the Australian continent receives so little rain, it is practically desert. Collectively known as the Great Australian desert, they are primarily distributed throughout the Western Plateau and interior lowlands of the country, covering areas from South West Queensland, Far West region of New South Wales, Sunraysia in Victoria and Spencer Gulf in South Australia to the Barkly Tableland in Northern Territory and the Kimberley region in Western Australia. By international standards, the Great Australian desert receives relatively high rates of rainfall or around on average, but due to the high evapotranspiration it would be correspondingly arid. No weather station situated in an arid region records less than of average annual rainfall. The deserts in the interior and south lack any significant summer rains. The desert in western Australia is well explained by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambush Predator
Ambush predators or sit-and-wait predators are carnivorous animals that capture or trap prey via stealth, luring or by (typically instinctive) strategies utilizing an element of surprise. Unlike pursuit predators, who chase to capture prey using sheer speed or endurance, ambush predators avoid fatigue by staying in concealment, waiting patiently for the prey to get near, before launching a sudden overwhelming attack that quickly incapacitates and captures the prey. The ambush is often opportunistic, and may be set by hiding in a burrow, by camouflage, by aggressive mimicry, or by the use of a trap (e.g. a web). The predator then uses a combination of senses to detect and assess the prey, and to time the strike. Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expandi ...

Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

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] |
