The venom contains neurotoxins, which attack the nerves. They are similar to those isolated from Phoneutria nigriventer and act on the ion channels (gates that control charged particles such as calcium, sodium and potassium) in nerve cells, and on NMDA-type glutamate receptors (chemical receptors in the brain and nerves). The venom also contains CRISP-1, a protein that acts as an allergen.1

E kotsi hakae ho batho?

Kotsi ho batho: E kotsi haholoE ka bolaya motho ya sa fumaneng kalafo.

This spider should be treated with caution. Studies on its close relatives are scarce, so less is known about this species than about some others. CRISP-1 is known to cause a dangerous allergic reaction in humans.1

Haeba e loma

  • Hlatswa moo e lomileng teng mme o bee pakete ya leqhwa hodima teng bakeng sa bohloko. Fumana thuso ya bongaka haeba bohloko bo le matla, bo phatlalla kapa motho a ikutlwa a kula.

Dintlha

1

Its venom contains neurotoxins that are similar to those of Phoneutria nigriventer, another species in the same genus.1

2

CRISP-1, a protein found in its venom, is basically an allergen, meaning it can trigger an allergic reaction.1

3

The family of proteins that includes CRISP has also been found in cephalopods, cone snails, scorpions, reptiles and ticks.1

4

Its venom neurotoxins act on NMDA-type glutamate receptors as well as ion channels in nerve cells.1
