What are the types of spiders?

Answer 1

I will give some facts about Spiders and kinds of it.

-They are an eight-legged creature that have organs to spill silk at the ends of their body.

-They are the largest part of the arachnid family.

*Arachnid family includes scorpion and ticks.

-All Spiders have the ability to bite with their venom-injecting fangs.

Bites:

Most of the spider do no harm than a bee sting or a mosquito bite. Most spiders with a life-threatening bite are quite shy and only attack when they feel threatened.

Spider venoms work on one of two fundamental principles; they are either attack the nervous system, or attack tissues around the bite

Researchers are investigating novel uses for spider venom, from an eco-friendly alternative to pesticides to treatments for Alzheimer's disease, cardiac arrhythmia and strokes. In addition, spider silk has lots of engineering uses, from body armor to optical communications.

Arachnophobia

Humans have long had a tumultuous relationship with the eight-legged critters.Arachnophobia, or fear of spiders, is one of the most common phobias. Some statistics show that 50 percent of women and 10 percent of men have the fear. Evolutionary biologists surmise that a modern fear of spiders may be an exaggerated form of an instinctive response that helped early humans to survive. Other scholars think that spider fears began in the Middle Ages, when spiders became a cultural scapegoat for inexplicable epidemics of the time, like the plague.

Three suborders

Spiders, which make up the order Araneae, are divided into three suborders, Mesothelae, Mygalomorphae and Araneomorphae:

Mesothelae: These are the small, light descendants of the most ancient types of spiders, and their living relatives reside in southeast Asia, China, and Japan. They live in silk-lined burrows with trapdoors, and lack venom glands - though they do have the mechanism to express venom through their fangs.Can you imagine yourself holding this tarantula?

Mygalomorphae: These spiders are generally heavily-built and hairy, like tarantulas. They live in burrows underground, and can prey on creatures as large as frogs, lizards, and snails. A few species build webs, but it is not very common. Although most spiders live for at most two years, many mygalomorph spiders can live up to 25 years in captivity. The largest tarantulas have a leg-span of ten inches.

Araneomorphae: These are the most common of spiders, making up more than 90 percent of all the species. They build webs and have fangs that close together like a puzzle, instead of the Mygalomorphae fangs that move in parallel with each other. Some of the most interesting species include the only known vegetarian spider, the Bagheera kiplingi, as well as the most venomous spider, the Brazilian wandering spider. Scientists have found that the spider only needs to inject 6 micrograms of its venom to kill a 20-gram mouse, and a full venom load is more than ten times that. People have died from a wandering spider bite after antivenom has been administered.

That's all and I hope you have learned something from this.
