Old world vs New World

[WhitenerJ]

im very new to Ts and was wondering what is the difference in old world and new world Ts?

Old World Tarantulas are found in the "Old World," meaning Africa, Asia, Europe, etc.

New World Tarantulas are found in the "New World," meaning North and South America. When the Americas were discovered, they were the "New World."

Most New World Tarantulas have urticating hairs as their main form of defense.

Old World Tarantulas have a nasty attitude and bite as their main form of defense.

To generalize, New World Tarantulas are a bit more docile than Old World Tarantulas. There are some exceptions, of course.

What Tarantula1995 said. OW's Theraphosidae are more prone to bite, nervous, some of those are extremely defensive (like Pterinochilus murinus) and they have, in general, a very potent venom (genus Poecilotheria, S.calceatum, P.murinus just mere examples) a venom able to send an adult man to E.R in pain (read some bite reports here if you are curious about)

Very interesting. So can OW and NW Ts coexist in the same habitat?

What do you mean for "habitat" man? Same room (where you keep your Arachnids) or... same enclosure?

Enclosure.

 

[Ellenantula]

Conditions will vary: some need dryer, warmer, moister, better ventilated, etc., conditions. I have kept both in same room, but not in same enclosure -- each receives their special housing needs. Some need room to climb, some need depth to burrow. Each T may vary in requirements. But kept in same room -- should be fine. Obviously in the wild, NW and OW do not share same habitat -- due to differing geographical locations.

Enclosure.

Short answer: never. Well you could but one of them would have very expensive meal - just kidding, of course. Mike Jacobi's book on tarantula keeping is a nice basic book and reasonably priced, maybe start there. Cheers.

Enclosure.

There are very few Ts that can be kept communally. For the most part they are lone dwelling hunters that will absolutely eat each other, even between members of the same species.

 

[Toxoderidae]

Another thing to remember is build. OW tarantulas (all, even terrestrials) have a much thinner, more athletic build, to run quickly and defend.

 

[Chris LXXIX]

Enclosure.

That's the worst thing to do.

 

[Flexzone]

Enclosure.

NO, Unless you want to recreate fight club

 

[Toxoderidae]

And who was the one who gave you the idea a primitive spider OF DIFFERENT SPECIES AND CONTINENT could be housed together? Like, people from different countries that border eachother can hardly coexist. And we're the most advanced creatures known on the planet. Just.. I know you like spiders and reptiles and such, but please for the love of Pelinobius muticus actually do some research on these animals. Just a little bit takes you a long way.

I don't think Ceratogyrus are that lean at all. The females tend to be stocky IMO.

total fatties...they plump like a Brachy.

True, they can get bulky, but it's different than with NW's. Females of some Ceratogyrus seem to produce eggs in advance of pairing, and will hold off molting waiting for a date. Marshalli are prone to this.
