Texas Brown Tarantula

The reason for the arachnid’s sensitivity to temperature doesn’t rely chiefly on their muscles to move, but they rather employ their blood which also called hemolymph.
The spider’s fluid is sensitive to temperature. Hence, when the hydraulic fluid flows into their tube-like legs, it makes them quite loosened and enlarged. An associate professor of biology at Harvey Mudd College in California and who spearheaded the study quipped that temperature can alter the thickness, or viscosity, of hemolymph.
Ahn said that at colder temperatures, the spiders moved at a slower pace since the hemolymph has become more viscous than at higher temperatures. Ahn made a conclusion that their study may aid engineers to study hydraulic robots.
She also said that, “Hydraulic extension has its limitations. And the limitations happen at the faster speeds, rather than the higher fluid viscosities.”

Texas Brown Tarantula
kill it, kill it dead!
HATER!
A favorite tool of cheap horror movies because they’re so big, but those of us from tarantula country just giggle, because they’re non-venomous. Though given the size of their fangs getting bit by one hurts a lot.
Does it hurt more than a yellow jacket or wasp sting? If not, then I won't kill it if I encounter one......
No. It hurts like getting jabbed with a small crochet needle. Which for jabbing purposes is basically what it is.
Thanks, that's good to know. Not that I'll ever encounter one here in Michigan but If I'm ever in a climate where they are I'll just let them be..........
A bald-faced hornet bite is very painful. They’re extremely aggressive and have dirty mouths. I was on antibiotics for six weeks after one followed me into the house and bit me on the foot.

Sorry about the double post.
I’ve seen those things. Creepy looking, but not very dangerous, especially when contrasted with the REALLY BAD tarantulas, or the damn brown recluse spider (I hate them).
Unless you find one in the bottom of your pantry and go to grab it 'cause you think your kids left it there to scare you.
You make a noise, but it' not a giggle. :-)
I can relate to that....
As a side note, this past late summer, my neighbors saw numerous juvenile bald-faced hornets on their wooden privacy fence and asked me about them.
I told them they were stripping the wood in order to help build their nest and that such nest was likely within a hundred yards of their deck........
Sure enough, when the cold weather came and the leaves fell, they found the basketball sized hive in the bushy tree right in front of their front picture window..........LOL!
Spiders.
When I was out in the Permian Basin, one of the neatest things I never had experienced until then was the sheer volume of Tarantulas that would be everywhere when the monsoon rains would come and flood their burrows.
Cute critter. Freaks people out when you pick one up.
