Most aggressive tarantula?

[Urticate]

What's the most aggressive tarantula species you believe there is.
What's a tarantula the most painful bite/venom?
All personal opinion!

 

[Chris_Skeleton]

Please just do a search. There are plenty of threads on this topic already.

Also, tarantulas aren't aggressive, they're defensive.

 

[Ultum4Spiderz]

yeah very easy to search.... Ive never seen a T attack without provoked.. they arent actualy agressive
Ts are defensive...

all Ts are mean when in a bad MOOD

 

[Terry D]

All of them!- with the exception of docile spp such as Stromatopelma calceatum, Heteroscodra maculata, Pterinochilus murinus, Haplopelma lividum, and Pelinobius muticus, of course (-;

No, but most likely candidate for defensiveness might be a better way to put it.

 

[loudan]

my guess is an obt or am H. lividum.

No bite experience (yet) so can't comment.

As for "leave me alone" threats, I *would* have said my OBT, but in all fairness it only stands its ground some of the time, the rest it bolts into it's webbed up plant-pot.
The one who really puts on a show is my juvenile A. geniculata, that one has some serious mental issues going on. It rears bolt upright, spins a full circle instantly if it needs to, kicking hairs everywhere the whole time and it stays wound up like that for a good half-hour or more after it's been left alone. If there's one T that I have that I could imagine holding some kind of grudge and coming out for revenge this would be the one!

I think it really depends a lot on the individual spider, too. I keep many notoriously defensive species, but one particular LP I have is the nastiest thing I've ever seen.

Yea do a search for an easy answer like this next time. Anyways ill be gracious.

Hottest venom Heteroscodra maculata.
Most defensive for me is my Chilobrachys sp. IDK (as in I don't knoe what sp. Yet) as far as biting or raising into threat posture. And for hair flicking, my LP. NASTY little man he is..

 

[catfishrod69]

S. calceatum has more potent venom.....and OBT and the good ole P. muticus are pretty defensive...

I had a very mellow OBT that I raised from a .5 inch sling all the way to an adult male. The only time he ever gave a threat pose or acted defensive at all was when I was trying to get him into a deli for shipping on a breeding loan. On the other hand I have a G. puchra that has reared up into a sorta threat pose on more than one occasion. It just does not like its overturned water dish messed with. LOL

Always read that Hmacs had the hottest venom. I'll take your word for it though

 

[catfishrod69]

they are second to the calceatum....S. calceatum is one of my favorites...i have 2 adult females and a MM...

Are there any publications on tarantula venom strength or is this anecdotal? Also, how is the strength being determined (LD50% in mice/rats/rabbits)? I can imagine there being a lot of variation depending on how the study is performed, and which animal it is being tested on. Plus, I would guess that venom toxicity would be strongest against primary prey type or primary predator, so there could be variation depending on what is being bitten. Another thing to consider, is the size of spider and amount of venom injected. I would probably prefer an S. calceatum sling to bite me than a 10" P. ornata.

I am going to post this thread relevant to the S. Calceatum issue. I thought the post was written well.

edit
I just read more of the thread on the Calceatum, is it true they can glide?

 

[catfishrod69]

im not sure i would rather have either bite me...and you never know a calceatum sling might punch out full venom, and the ornata might give you a dry bite....soooo that would suck....as far as the studies, i have no clue...but everything i have read is that the S. calceatum is the worst, check out this thread...http://www.arachnoboards.com/ab/sho...s-the-most-potent-venom&highlight=worst+venom

yes they can glide...and wet glass? not a problem...they can run upside down on it....

Maybe they're both hot in venom Cus they look alike at a quick glance lol not exactly but you can see the similarities

ummmm...."gliding". What does this mean?

As for defensive/aggressive. My lil' L. klugi that came in at 0.25 and has molted to 0.5 used to hide ALL the time, now I open the lid and it runs out to ck it out -- something tells me it is going to grow in to be quite the little booger. For some reason I thought it would be a slower spc.

 

[catfishrod69]

gliding...the same as gliding....like jump then glide...not fly..

My favorite T is the H.mac. I love her colors, even though she still hasn't started to get her true female colors yet. The S.calceatum is a beautiful T, and I would love to have a large one in a nice tall terrarium. There legs are unbelievable too! And as for gliding, my H.mac has jumped before, and I was pretty suprised how far she got. I can't wait to see one of these jump ima go YouTube it.... Haha

 

[ijmccollum]

hmmm...sounds like interesting behaviour....would be interested in seeing this. Anyone know if there is video of it?
