The West Coast button spider is a small black spider that lives in Namibia and South Africa. It is one of the black button or black widow spiders, and its venom acts on the nerves. Knowing what it looks like helps people stay safe in its dry habitats.1

This spider has neurotoxins called latrotoxins, which act on nerve endings. Within 15 minutes of a bite there is intense pain, a burning sensation and swelling. Intense muscle pain and cramps can develop about an hour later, along with anxiety, slurred speech, nausea, headache, sweating and fever.1
