Are you fascinated by spiders? Do you want to learn more about one of the most venomous and aggressive spiders in the world? If so, this blog post is for you! In this post, I will tell you everything you need to know about the wandering spiders, also known as Ctenidae.
Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts.
Wandering spiders are a family of spiders that includes the Brazilian wandering spiders, which are sometimes called banana spiders because they are often found on banana leaves. They live in tropical and subtropical regions of Central and South America, where they hunt for prey on foliage and on the ground. They have a distinctive groove on their carapace (the upper part of their body) and strong bristles on their first two legs.
Wandering spiders are nocturnal hunters that use their excellent vision and speed to catch insects, frogs, lizards, mice and even birds. They do not build webs but wander around looking for food. They are very defensive and will not hesitate to bite if they feel threatened. They have an intimidating posture where they raise their front legs straight up into the air.
Wandering spiders have a powerful venom that affects the nervous system of their victims. Their venom can cause symptoms such as pain, swelling, nausea, sweating, salivation, irregular heartbeat and difficulty breathing. In some cases, their venom can also cause priapism (a prolonged painful erection) in men. This condition can lead to impotence or gangrene if not treated promptly.
The most dangerous species of wandering spiders are Phoneutria fera and Phoneutria nigriventer, which are responsible for most human deaths from spider bites in South America. These species have a leg span of up to 15 cm (6 inches) and can deliver up to 0.6 mg of venom per bite. The lethal dose for humans is estimated at 0.2 mg.
If you ever encounter a wandering spider, do not panic or try to touch it. Keep a safe distance and try to identify it by its size, color and markings. If you are bitten by a wandering spider, seek medical attention immediately. Antivenom is available for some species but not all.
These spiders live mostly near ponds, rivers and other freshwater habitats, and can walk on water due to fine air-trapping hairs on the tips of their legs. They can also dive under the surface, and can stay underwater for over an hour by using the air trapped in hairs surrounding their book lungs. They will consume anything from insects to small lizards and, occasionally, small fish. One of the most important may be the ability to detect chemical marks of prey, they can efficiently detect the tracks of some of the potential prey, thats why they also called “tropical wolf spiders”. Despite all this, they are very caring mothers and stay in place and feed their young for almost a year.
Wandering spiders are amazing creatures that deserve respect and admiration for their hunting skills and adaptability. However, they are also very dangerous animals that should be avoided at all costs. I hope this blog post has given you some insight into these fascinating arachnids.
