This is my adult tarantula - she is female. Her name is Acanthoscurria geniculata and this species is commonly knows as Brazilian whiteknee tarantula or Whitebanded Tarantula. This one is really big one and I fed her using one mouse. She striked quickly and the mouse had no chance to survive. In this video you can see how this tarantula cought the mouse and then how it looked when she was eating it. It took more than 33 hours to eat the whole mouse. I reccomend you to read everything and consider if you want to see brutal (but natural) process of tarantula's eating.
