Giant huntsman spider
The Goliath birdeater tarantula is found in the South American rainforest and is the largest spider in the world. You need a large meal when you’re a spider the size of a dinner plate . A fully-grown Goliath birdeater has a leg span of about a foot, and a thick, heavy body that can weigh as much as 7 ounces.

Spiders range in body length from 0.5 to about 90 mm (0.02–3.5 inches).
If these hairs embed in an animal’s skin or eyes, they cause itching and discomfort. Although venomous with inch-long fangs, the Goliath Birdeater’s bite will not kill a person. It will, however hurt quite a bit, and has been described as somewhere between the pain of a wasp sting and hammering a nail into your hand.
They do not have venom glands, fangs or any other mechanism for chemically subduing their food. Therefore, they do not have poison and, by the powers of logic, cannot be poisonous from venom. Some have defensive secretions that might be poisonous to small animals if ingested.
Defining the term “most venomous” as the most toxic to humans (as some venomous spider species show varying degrees of toxicity to different animal species envenomed by them), the world’s most venomous spider is the male Sydney funnel-web spider Atrax robustus .
Even if a spider DID want to chase you down, it probably couldn’t. With an open circulatory system, spiders don’t have a system of veins and capillaries for oxygen distribution through the body. But do know that spiders aren’t out to get you , aren’t mad, and honestly would prefer you not poke them with a stick.
Wolf spiders (Lycosa) aren’t deadly to humans, but they can still bite and cause uncomfortable symptoms. These spiders are found across the United States. A wolf spider bite isn’t usually a cause for significant concern because they’re not poisonous to humans. If your symptoms worsen, call your doctor.

The venom from this spider is packed with at least 40 different toxic proteins, which can overload the body’s nervous system and reportedly kill someone in minutes. “With a funnel web bite to the torso, you ‘re dead,” Dr.
When spiders get sucked into a vacuum cleaner, can they eventually crawl back out, or do they suffocate in all that dust? Almost every spider sucked into a home vacuum cleaner will die —either immediately, from the trauma of ricocheting through the machine’s narrow tubes, or eventually, from thirst.
Despite their often large and hairy appearance, huntsman spiders are not considered to be dangerous spiders . As with most spiders , they do possess venom, and a bite may cause some ill effects. However, they are quite reluctant to bite, and will usually try to run away rather than be aggressive.

Spiders have the same basic bodily systems as people, but they don’t work in the same way and they’re arranged differently in the body. The cephalothorax contains the brain , stomach, eyes and mouth, and the abdomen contains the heart , digestive tract, reproductive organs and lungs.
