Also known as: Australia’s cousin of the black widow.

• Geographic range: Throughout Australia, increasingly common in urban areas and even overseas (e.g., New Zealand, parts of Asia).
• Venom profile: Similar to black widow latrotoxin, causing severe pain, sweating, nausea, and muscle rigidity.
• Bite frequency: Often occurs when the spider is trapped against skin (e.g., in shoes).
• Medical notes: Antivenom is available in Australia; symptoms usually resolve within a few days with proper care.

Why it’s dangerous: Its expanding urban presence raises the odds of accidental contact.
