Defensive behavior: Brazilian Giant White Knee is a bold tarantula, but not aggressive as an adult. It may use a defensive pose, but would rather retreat than stand and fight. It rarely kicks hair.

Bite danger: If you are bitten, this has been likened to a bee sting. A small percentage of people are allergic to bee stings so care should be taken.

Handling: Always use caution when handling any tarantula, no matter how docile.

Diet/Nutrition: This is a hungry, greedy tarantula. Brazilian Giant White Knee spiderlings eat pinhead crickets and other small insects. Adults eat crickets, other large insects, small lizards, pinkie mice, and an occasional fuzzy mouse.
