Phormictopus cancerides and Phormictopus auratus difference

[BrokenLegBaboon]

I just ordered a stirmi and looking for a sling to add some spice. Should I go for cancerides or auratus? And what are their average sizes? I was informed that auratus are smaller

 

[Vanisher]

P cancerides gets bigger as you say. Getting up to maybe 9 inch! P auratus i am not sure? Their coloration is totally diffrent to. P auratus are golden in volor and more stocky build? If i where you i would buy both of them!

I wanted something different so i got auratus and sp south hispaniola. I think cancerides is the biggest of all phormics but not sure

P. atrichomatus is the largest, not sure which one is the runner up, heard that sp. gold carapace is

So cancerides isn’t the biggest of their genus? Anyone have atrichomatus adult pic?

Oh and do P.auratus behave like cancerides too? Do they also have that great feeding response? And how big do they get?

From what I've read, P. auratus are a bit more calm and less defensive than P. cancerides, but I only have my sub-adult female P. auratus for reference. She is an amazing eater, and I have no doubt she'd eat everything that all my other tarantulas refused if I let her. No messing about when something drops onto the substrate with that lass -- she's a pretty active hunter once she thinks something is nearby, and rarely sits and waits for things to come to her.

According to whom?

I dont have the atrichomatus, but my AF cancerides is over 8".

Hmm why do some cancerides (female) appear purple ish and others look more black?

Whoops re-read a paper and it had said cancerides tend to be more ‘robust’ and larger. Shouldn’t go off of memory anymore..

Well my 2 auratus slings tear up crickets like nothing I have ever owned. Once the cricket hits the substrate, it's on like donkey kong. I don't know how big they get. I am guessing around 6 inches honestly. Supposedly Cuban phormics are the relative dwarfs of the genus. In my opinion, they might be the best looking.

All good.

They go through some interesting color changes as they grow, my female went from brown to black on her last molt.

That’s cool! Just asked my friend who keeps them and he said that every time they molt it’s like you have a completely different spider lol!

Can I have the link to that paper? I want to read it too

Yeah pretty much, one of the many pros of keeping Phormictopus.

 

[nicodimus22]

what size was it when it started to gain the ‘gold sheen’?

I have two that are a little less than 3 inches DLS, and you can already see it on both.

 

[Goopyguy56]

I know this is oldish but i was able to get a few pics of my sling to see if it might be p auratus. It isnt blue but it has a red abdomen. 2 pics, one without flash and one with it on

 

[nicodimus22]

^ What are you disagreeing with, exactly?

 

[Goopyguy56]

Just skeptical that what i purchased is auratus. Didnt know if others that commented on this thread had auratus that looked like this

That's fine, but if you're not sure what you have, why are you disagreeing with my comment? I know that I have two P. auratus, and they both show some gold on the carapace already.

Sorry, I wasn't dissagreeing with you. I wasn't responding to anything you said. I previously said that I did not think that my t was an auratus and someone asked if i could post a pic on this thread. I should have been more specific
