Fun facts

  • GeneralIt digs burrows over 1 m deep and can live more than 25 years.
  • It stridulates by rubbing the bristles of its chelicerae and produces an audible hiss as a warning before it strikes.
  • Unlike the American tarantulas, the African ones have no urticating hairs: they defend themselves by biting, and their venom causes intense pain and prolonged cramping.
  • It is one of the longest-lived tarantulas: females can live more than twenty-five years.
  • It is extremely fossorial: it digs tunnels up to two metres deep and virtually never leaves them, so in captivity it is a species that is almost never seen.
  • It stridulates when disturbed: it rubs the bristles on its chelicerae and pedipalps to produce an audible hiss, a warning uncommon among tarantulas.
  • Unlike the American tarantulas, the African ones have no urticating hairs; their defence is stridulation and, failing that, the bite.
  • Its venom is not lethal to people but causes severe, prolonged pain and cramps.
