Chemically Receptive hair

[jrh3]

So I am watching an episode on Netflix of Night on earth, episode Jungle nights, 24 min. in, there is a curly hair Tarantula, the commentator says, “ with chemically receptive hairs, she smells her victim’s approach.

Where do they get this info from? Just make up something that sounds good for tv? I can't believe they consider this to be a documentary.

Dude you didn’t know this? Your late to the game I think the scientific term is chemical smell-o-vision. You can quote me on that

So maybe we can spray cricket scent on an apple, yeah that should work haha.

Well, everyone should know that tarantulas, especially curly hairs, may lack acute vision, but make up for it with their exquisitely sensitive chemoreceptive setae! These special hairs have the ability to detect a mealworm from over 3 miles away! That's why tarantulas are seen wandering the roads in the fall....they smell crickets. These hairs can also cause irritation because they will cause intense itching if they detect the scent of a predator.

Here's an interesting topic.

Tarantula brains (or lack thereof....)

I have read many times here and elsewhere that tarantulas do not have a brain, cannot think, feel emotions, etc. The little reading I've done on this seems to base this conclusion on physiological data, e.g. organization of nerve clusters and the like, but I don't recall seeing a lot of...

There is also a whole general explanation about chemical senses and olfaction in spiders on Biology of Spiders (Foelix), and smell is also mentioned a lil bit on TKG.

If bet they have some kind of smell , maybe not the way we think about it. I doubt it’s on septae though

males seem to be able to sense females from a distance when the females are in an adjacent enclosure or not moving at all. I’m not sure how they do it but I’d assume it’s a pheromone

I bought this e-book a few months ago and love it. It's fascinating stuff. Highly recommend it!

If you see it on tv it must be true.
Documentaries on Netflix often seem to lack factual information and eat time like langoliers!

It may be possible, however.
I don't know how they do it but they "smell", somehow.

Langoliers! Hadn’t heard that in a long time. I loved that movie as a kid... bowling balls with teeth that eat the past

They're here, dude!
They look like shiny rectangles.

Oh they can smell alright, as soon as i walk in from a sweaty day at work they all just shoot down their holes as soon as im within 6 feet of their shelving

They do have chemo-sensory "hairs", but (generally speaking) not for the purpose of prey finding/hunting. More so for intraspecific interactions and "interpreting" the environment they are in. It also helps them differentiate between regular air movement and breath from a vertebrate.
