Advertisement I always thought the longest s T could live was 30 years, and that was relegated to the slowest growers like B. smithi and G. porteri. But I've heard of tarantulas lasting longer. @cold blood has a G. porteri that's over 30 now, and showing no signs of slowing down. Dang. So who's your longest lived T? Or the longest lived T you've heard of? Heck, while we're at it, we could throw scorpions in the bucket too.
