Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

Its venom contains an excitatory neurotoxin, which attacks the nerves that control involuntary body functions and releases adrenaline and related chemicals. Mild cases cause mainly localised pain, while more serious cases can bring fever, sweating, tremors, vomiting, agitation, a fast heartbeat and inflammation of the pancreas. Deaths can occur within 1 to 6 hours, or 12 to 14 hours, depending on age, health and the amount of venom injected.1

Hoe gevaarlik is dit vir mense?

It is responsible for more medically significant accidents than any other scorpion in Brazil, and most of the country's fatal scorpion cases. Mortality rates are 1.0 to 2.0% among children and elderly people. In a nationwide study from 2000 to 2012, Brazil recorded 482,616 scorpion accidents and 728 deaths, and this species was believed to cause most of those deaths.1

Wat doen dit as dit bang is?

It uses its tail barb to deliver defensive strikes.1

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Reported scorpion stings in Brazil rose from 12,000 in 2000 to 140,000 by 2018.1

It has a low metabolic rate, so it can survive for months without eating.1

Scorpion numbers have grown in Brazilian cities, helped by plenty of cockroaches to eat and few predators.1

Its venom varies by region. Scorpions from Distrito Federal have an LD50 of 51.6 μg/kg, compared with 26 μg/kg for those from Minas Gerais. LD50 is the dose that kills half of the animals tested.1

Its tail is bulbous and segmented, with ridges and serrations, and it often curls forward over its back.1
