'Big boy' spider is Australia's largest deadly funnel-web spider
Australia is known for its diverse array of unique creatures, and among them is the "Big Boy" spider, which is now recognised as Australia's largest deadly funnel-web spider. The "Big Boy" spider, also known as Atrax christenseni, is one of three species of the Sydney funnel-web spider, previously thought to be a single species. The Sydney funnel-web spider was first described in 1877 as Atrax robustus, and is found throughout the city and suburbs of Sydney.
The "Big Boy" spider was discovered in the early 2000s by Kane Christensen, a spider enthusiast and former head of spiders at the Australian Reptile Park. It was first found near Newcastle, about 170 kilometres (105 miles) north of Sydney. The spider is described as dark and glossy, with fangs so big it could bite through a human fingernail. It is the largest of the three Sydney funnel-web spider species, growing up to 3.5 inches (9 cm) long.
The discovery of the "Big Boy" spider highlights the hidden diversity among funnel-web spiders and underscores the importance of ongoing research to understand these arachnids better. While funnel-web spiders are not aggressive by nature, they can attack when cornered, so it is essential to be cautious when encountering one. The "Big Boy" spider's venom is particularly potent, and its fangs are longer than those of other funnel-web spiders.
The current antivenom is effective against bites from the "Big Boy" spider, and there have been no recorded deaths from funnel-web spiders since the antivenom was developed in 1981. However, confusion about the different species of funnel-web spiders may impact the effectiveness of antivenoms. By studying the specific compounds in the venom of each species, researchers can tailor antivenoms to improve their specificity and better protect humans from these deadly spiders.

Giant huntsman spiders are the largest member of the Sparassidae family
Huntsman spiders are known for their long legs, which twist forward in a crab-like fashion. They are often confused with tarantulas or brown recluse spiders due to their size and coloration. However, their venom is considered less dangerous to humans than that of a brown recluse. The giant huntsman spider is yellowish-brown with several irregularly distributed dark spots on the rear half and wide dark bands on the legs before the first bend.
These spiders are not known to be aggressive, but they can bite if they feel threatened. They are considered beneficial in Australia because they feed on large insects such as cockroaches. Huntsman spiders are also quite fast, moving up to a yard (almost 1 meter) per second. They are sometimes called "wood spiders" because of their preference for woody places like forests, mine shafts, and wooden shacks.
In addition to the giant huntsman spider, there are other large huntsman species, such as the banded huntsman (Holconia), which is grey to brown with striped bands on its legs, and the badge huntsman (Neosparassus), which is brown and hairy. The tropical or brown huntsman (Heteropoda) is also large and hairy, with mottled brown, white, and black markings.

Huntsman spiders are not aggressive but can attack when cornered
Australia is known for its diverse array of unique creatures, including the giant huntsman spider, one of the country's largest spider species. Huntsman spiders are large, fast-moving spiders found in various parts of the world, including Australia, Asia, Africa, and the Americas. They are often mistaken for being highly venomous, but their venom is not considered medically significant for humans. While their bites can be painful and cause localized symptoms such as redness, swelling, and discomfort, they are not known to possess venom that poses a serious threat to human health.
Huntsman spiders are not aggressive towards humans and do not actively seek out human interaction. They are more inclined to flee or hide when confronted rather than attack. Bites from huntsman spiders are relatively uncommon and typically occur when a person accidentally touches or attempts to handle the spider, or when the spider perceives a threat and defends itself. In such cases, a huntsman spider may bite as a defensive reaction.
The giant huntsman spider is the largest member of the family Sparassidae, with a leg span of up to 30 cm (12 inches) and a body length of 4.6 cm (1.8 inches). It is characterized by its long legs, which twist forward in a crab-like fashion, and its yellowish-brown coloration with dark spots and bands. The giant huntsman spider is found in Laos and is believed to be a cave dweller due to its physical characteristics.
While huntsman spiders are generally not aggressive, they can attack when they feel threatened or cornered. It is important to be mindful when encountering these spiders and to avoid touching or handling them, as they may bite in self-defense. However, their bites are typically mild and short-lived, and severe allergic reactions to their venom are exceedingly rare.
In conclusion, huntsman spiders, including the giant huntsman spider found in Australia, are not aggressive by nature but can attack when they feel cornered or threatened. While their bites can be painful, they are not considered medically significant, and severe reactions to their venom are rare. It is important to respect these spiders and give them space to avoid any potential defensive reactions.

The giant green-bellied huntsman spider is one of Australia's largest spiders
Australia is known for its diverse array of unique creatures, and among them is the giant green-bellied huntsman spider (Typostola barbata). This spider is one of Australia's largest spider species and can be found along the country's eastern coast. It is a member of the huntsman spider family, Sparassidae, which is native to tropical and warm temperate regions worldwide. Huntsman spiders are known for their hunting abilities, using their speed and agility to catch prey rather than building webs. They are also distinctive in appearance, with their long legs twisted in a crab-like fashion and their vibrant green underside.
The giant green-bellied huntsman spider is not as large as some internet images suggest, but it still boasts an impressive leg span of around 20 centimetres (almost 8 inches). This makes it one of the largest spider species in Australia and an imposing presence in its native habitat. While it may appear intimidating, this spider is not aggressive towards humans. In fact, they tend to avoid humans and are more interested in going about their "spidery" business in the bush, eating bugs.
Like most spiders, the giant green-bellied huntsman uses venom to immobilize its prey. However, its venom is not considered to be highly dangerous to humans. The spider's legs bear prominent spines, while the rest of its body is smoothly furry. They can be found living under rocks, bark, and in other natural shelters, as well as in human-made structures like sheds and garages.
The giant green-bellied huntsman spider is just one of the many unique and fascinating creatures that can be found in Australia. While some may find them frightening, they play an important role in the country's ecosystem and contribute to its rich biodiversity.
