And since we have this sweet thread about big spiders, we need what's thought to be the worst bite out of all the poisonous arachnids, the Brazilian Wandering Spider (also refered to as the banana spider.)
Bite: Life threatening, highly toxic venom (one of the most neurologically active), and is regarded as among the most dangerous spiders in the world. May hitch a ride in clusters of bananas and has been found in the United States. Many bites are dry bites. One of the most excruciating of all spider bites because of the large size of the chelicerae (fangs) and high levels of serotonin contained in the venom.
Symptoms:
* Loss of muscle control, and breathing problems, resulting in paralysis and eventual asphyxiation.
* Causes intense pain and inflammation
* Extremely painful bite and immediate pain.
* Heavy perspiration and drooling
* Priapism
Treatment:
* Seek medical attention immediately.
* Keep the patient calm and quiet to avoid spreading the venom.
* An antivenin is available for the bite.
