The source of many of phobias, dark images and negative press. Yes there are some to beware of, and all spiders have a venom. BUT! There is just a small percentage of spiders that contain any venom that effects humans and for the most part, spiders help control the quality of our lives from pesky insects that can make our lives miserable.
By spending so much time in the jungle, I just realize that I am NOT the top of the food chain and the I may just be asking to be a traveling
snack bar by running around in shorts all the time and usually barefoot.
That is for the most part because I don't wear repellent, and that I like to see things close up. In any case, I have only ever been spider bitten twice in my entire life! So please don't panic. Face your fear when you see one, keep your distance but let them provide their service on earth as well.
Fishing Spider Brachypelma vagans
Normally, fishing spiders stand on the water with only their hind pair of legs anchored to the shore, but this one might be on land because it's detected my presence, or because the water is flowing very rapidly.
As their name suggests, fishing spiders hunt in water, taking other bugs which have fallen in, or even catching tadpoles or very small fish under the water. They detect the ripples made by their prey, and then go out on the surface of the water to capture it, using small hooks on their front legs. They usually attach a silk safety line to the shore to prevent themselves from being carried away by any current.
When they crawl underwater their bodies are surrounded by a thin, silvery pocket of air, which allows them to continue breathing. They're covered with hairs which repel water, so when they resurface they're completely dry.
Being in the open makes spiders very vulnerable to predators, so the hundred or so species of fishing spider found around the world are nocturnal hunters. They have hairs on their legs which are very sensitive to vibration, allowing the spiders to distinguish struggling insects or moving aquatic animals from waves generated by the wind or by the flowing water. They can even work out how far away their prey is, and in what direction.
Golden Orb Nephila clavipes
Called banana spiders, golden silk orb-weavers, golden silk orb-weavers and probably more. There are more than 150 species and new ones are discovered every year. Prized for their silk in Austraila these are some interesting spiders. Click the image to learn more.
Spinybacked orbweaver SpiderGasteracantha cancriformis
Females are 5 to 9 mm long and 10 to 13 mm wide. The six abdominal spine-like projections on the abdomen are characteristic. The carapace, legs and underside are black with white spots under the abdomen. Variations occur in the colour of the upperside of the abdomen with black spots on white to yellow ground colour and red spines or yellow instead of white. Spines are sometimes black. Like in many other spiders, males are much smaller (2 to 3 mm long) and longer than wide. They are similar to the females in colour but have a gray abdomen with white spots and the spines are reduced to four or five stubby projections.
You probably have had more opportunity to come across these in the United States than here where it is not all that common, but this is a creature worthy of knowing about, and from personal experience, one to be knowledgable about.
The Chilean recluse spider is a venomous spider, Loxosceles laeta, of the family Sicariidae (formerly of the family Loxoscelidae). In Spanish, it (and other South American recluse spiders) is known as araa de rincn, or "spider of the corner"; in Portuguese, as Aranha-marrom or "brown spider". This spider is considered by many to be the most dangerous of the recluse spiders, and its bite is known to frequently result in severe systemic reactions, including death.

Tarantula Brachypelma vagans
There are a couple varieties of tarantulas here, but as you may have seen, unless they feel they are being attacked, they are also kept as pets in many places. We have black and Mexican redrumps which are reported from Belize, El Salvador, Guatemala, Honduras and Mexico. Tarantulas can live up to 35 years and grow up to 11 inches. They hunt at night for insects, small lizards, small birds and rats. Their venom pre-digests their victims tissue so it's easier to eat. Last but not least the female has up to 2,000 eggs at the same time.
Tailless Whip Scorpion
Amblypygids are also known as tailless whip scorpions. Even though they are related to scorpions, they are harmless! The name "amblypygid" means "blunt rump", a reference to a lack of the telson ("tail") carried by related species.
The long "antennae" are actually the first pair of legs, which have become extremely thin, very long, and covered with sensory receptors. As they walk, they hold one of these long feelers in front of them, and one out to the side, in order to detect whatever is out there. If they touch a prey item with one of these feelers, they capture it with the large spiky pedipalps at the front of their body.
Approximately 5 families, 17 genera and 136 species have been described. They are found in tropical and subtropical regions worldwide. Some species are subterranean; many are nocturnal. During the day, they may hide under logs, bark, stones, or leaves. They prefer a humid environment.
Because of the size of this spider, it is commonly mistaken for a tarantula. Have no fear though, yes they have fangs that you can see, but these are very beneficial spiders as they feed on household pests. They are normally seen in fields and I will write more as I research them for you.
