Acanthoscurria geniculata Volcano
In the early evening Adam came to me and told me his tarantula, a juvenile female Acanthoscurria geniculata, was building something. I went up to his bedroom to have a look.
The tarantula had been moving a lot of substrate to make its burrow larger and shaped it like a turret, or like a volcano as I said to Adam. Some of the substrate covered up the bottle cap that is used to provide water, hence the very moist spot to the right of the volcano.
Adam got this female tarantula as a belated birthday gift the 20th of May, 2020.
