Myth: Eight Legs Are Only For Spiders

There's an idea floating about on how spiders are the only animals in the world to have eight legs and that is a disturbing myth to hear on how people think spiders just magically formed 8 legs during their evolution and it clearly isn't true. Spiders had formed their legs from the Cretaceous Period similar to what the horseshoe crab's legs on how similar their structure is compared to spiders. All animals in the Arachnid group are not just spiders and that everyone in this group have eight legs so only spiders with 8 legs is definitely not the case.

Tarantula Fun Fact #1: Web Size

Image
Spider webs are one of the smallest things a human can perceive with the naked eye of average eyesight. The human's limit of sight are 0.1 millimeters (100 micrometers) while the smallest web width is around 0.3 millimeters (webs range to around 0.3-0.8 millimeters width). But typically, tarantulas have thicker webbing than other spiders because of how the webs are extremely similar to cobwebs when spread about the floor. Now, I'm not particularly saying that spider webs are the 2nd smallest things we can see and that there are sizes around the egg cell like dust particles that can be seen in the sunlight or particularly small crumbs. Fun-fact inside a fun-fact: The upmost tiniest thing a human can see is a human female egg (female eggs are the biggest cell in the human body) and that sperm cells are the smallest cells.

Fun Fact #5: Formidable Infestation

Image
Once the spider population in a home is so over grown, not only in basements and dusty corners but in everyday rooms can be overcome with extremely dangerous types of spiders like a huntsman, recluse, tarantula or even black widow can kill. Many don't know how spiders anatomy works especially when it comes to their defenses like venom and how their venom is regained over a certain amount of time. Depending on the genus, a couple of bites could kill and so even though spiders usually aren't aggressive, this could still pose a huge threat particularly when neighboring spiders are close within territories, causing stress. This could mainly cause a threat against weak or vulnerable people like new born babies, elderly, or in dire need of help of an illness. But don't fret, these demonstrations would be considered a rare case because of how unlikely it is to happen since there are many ways on preventing a huge spider infestation in human-active places but nonetheless, be weary

Substrate

Image
I've been following a subreddit for tarantula lovers and many people keep saying that owners need to keep putting more substrate into their habitats. I do totally agree that tarantulas need a lot of room for their man cave (burrows) but they definitely do need room to use their webs and more space to actually catch their prey.
