B. smithi rehoused and now stressed out

My jumper will literally tackle a cricket from across its cage, nifty little hunters

I wish there was a jumper the size of a large tarantula.

These are the largest jumpers

Orb weavers lay and wait as well, though there are a few species which don't spin the characteristic web we are familiar with if I recall correctly.

I own a few black widows and brown recluses. The instant that they know there is prey in that enclosure, they'll scurry around after it until they get it. It's quite funny with black widows, they often have trouble getting through the mess of web that they laid down.

True, they seem to be nimble only when they need to escape hah.

Ts don't have the eyesight that Jumpers have. They can discern movement.

Yes, but that movement could be perceived as a threat, don't you think?

That's HUGE compared to my Phidippus audax! I totally agree that I wish there was a T sized jumper, I love their personality and activity. I hope I see some next year in my yard from the sacs I've released this year

In point of fact, I'm not sure which species have "good" eyesight, nor are we sure what they observe. Observations from owners indicate arboreals tend to have better vision than terrestrials. A few of my Avics and Pokis could at least detect my movement up to 6 ft away. But what they perceived I don't know. I suspect it was a change in shadows personally. Their eyes aren't that complex to begin with, so they are limited there.

Also, like humans and other predators, jumpers have forward facing eyes, and tarantulas don't. Their eyes are mounted facing upward.

There's very little research done on T physiology. The majority of the vision research is done on true spiders, typically Jumpers for obvious reasons.

I'm honestly not sure what they observe.

Their early warning system is vibration. While I don't know for sure, I speculate they would react to the vibration of air currents long before movement generally speaking.

Makes me want an animal research lab. I love biology.

@JumpingSpiderLady @viper69 theres a discription of a study conducted on the vision of aphonopelma which noted that the main pair of eyes are less functional than the secondary eyes. http://thebts.co.uk/forums/showthread.php?4465-A-hello-and-a-few-questions!&p=33943#post33943

Yep I have that paper, old news That's the spectral sensitivity paper.

You may want to post a link to the actual paper however for others.

Thanks!

Yup, 'Scrooge' :-s

Everyone that doesn't offer to their T's a good level of inches of substrate (btw, aside for the "height safety mode", you never know if T's feel or wants to burrow a bit) IMO is a 'Scrooge'.

I understand, but as i said, in the other one he will have waaay more substrate, got it yesterday actually

Love the way how they can stare to you haha

If jumping spiders were the size of tarantulas they would take over the world... they're curious so they're intelligent and ferocious!!! LOL

My B. Smithi will hunt his food down. On the daily, he's the slowest thing ever. But toss in a cricket, and once he knows it's there, bam! He can jet. I agree with the others on the amount of substrate, for sure. A fall from that height could be super dangerous. I feel for the guy, being all bald. Hopefully the few fixes to the enclosure will fix whatever his nervous issue is.
