26th February, 2024

CHIRANJIT MITRA

● Found in Australia, this spider's venom is highly toxic to humans. ● Bites can cause severe symptoms, and fatalities have been recorded, though an antivenom exists.

Sydney Funnel-Web Spider (Atrax robustus)

Brazilian Wandering Spider (Phoneutria species)

● Also known as the banana spider, this South American native is highly aggressive. ●  Its venom is a potent neurotoxin, and bites can cause intense pain, paralysis, and potentially death.

Brown Recluse Spider (Loxosceles reclusa)

● Found in North America, the brown recluse's venom causes tissue necrosis (tissue death around the bite site). ● Severe bites can lead to significant, gruesome wounds and systemic illness.

Redback Spider (Latrodectus hasselti)

● Australia's answer to the black widow, the redback, has potent venom causing severe pain. ● While deaths are rare, young children and the elderly are more vulnerable to its venom.

Black Widow Spiders (Latrodectus species)

● Found worldwide, black widows (and related species) have venom that attacks the nervous system. ● Bites cause severe pain and cramping and can be dangerous for children and the health-compromised.

Mouse Spider (Missulena species)

● Australian mouse spiders are closely related to funnel-webs, with similarly potent venom. ● While less aggressive, their bites can cause severe symptoms and require medical attention.

● Native to Southern Africa, its sand-colored body makes it almost invisible. ● The venom of this spider causes tissue necrosis and potentially organ failure.

Six-Eyed Sand Spider (Sicarius hahni)

● The most dangerous recluse species is found in South America. ● Its venom is more potent than other recluse spiders, causing severe necrosis and sometimes fatal complications.

Chilean Recluse Spider (Loxosceles laeta)

● Found worldwide, yellow sac spiders can deliver painful bites, causing some necrosis. ● Though usually not life-threatening, severe reactions can occur, especially in children.

Yellow Sac Spider (Cheiracanthium inclusum)

● While primarily a tarantula, this Asian species is large and has a powerful, painful bite. ● Its venom causes severe localized pain and swelling and can induce hospitalization in some cases.

Chinese Bird Spider (Haplopelma hainanum)
