Theraphosa blondi & stirmi comparison

MaximusMeridus · Feb 20, 2013

After quite a bit of time with both Theraphosa blondi and stirmi and little information on comparisons other than setae on patella, here are 'my observations', of which seem to be consistent across all specimens.

Conclusion: T.stirmi is bigger built, more proportional, more agile, more powerful with longer legspan and T.blondi is hairier, less agile, stumpier and but far prettier.

For reference 2 adult females compared both with 4.1cm carapace width.

so then are saying from your picture that T. stirmi generally get to larger sizes then T. blondi, because that would be interesting

MaximusMeridus · Feb 20, 2013

My observations, due to significantly proportionally longer 1st exoskeleton segments i.e. femur and chelicerae, results in a stronger, longer(~1-1.5cm legspan), marginally heavier spider with the same carapace width. That doesn't however mean that the largest ever found in this respect is a T.stirmi although all indications show that T.stirmi and blondi share records and growth patterns for same carapace width.

Wow, nice analysis. What about apophysis though? Any comparable info on him?

Thanks for sharing.

Very nice, really appreciate this. Before I noticed there was a difference, I used to wonder why some "blondis" appeared hairy and others more hairless, I put it down to picture variations and lighting or regional variations of the same sp, which is technically true.

Adding an Apophsis to this comparison would be epic.

Very interesting!!
What about Goliath Pinkfoots?? I heard they get very large

+1 Adding T Apophsis :biggrin:

I never thought T. stirmi was much bigger.
Anyways, this should be pinned! Thanks!

Very cool, I miss my T Stirmi. He was my first tarantula ever and I recently lost him after 3 years to his own self destruction. The stupid spider started wandering aimlessly around his cage and climbing up the walls until he lost 3 legs and became so physically damaged he died. This post makes me want to get another theraphosa!

SpiderFreak585 · Jul 17, 2014

So im confused, does the stirmi really get more powerful and larger than blondi, just please somebody give me some info on these species, i would greatly appreciate it
