Arizona Bark Scorpion or Centruoides sculpturatus
Found in our house. Nasty little guys particularly for small children and seniors because they are the most venomous scorpion in North America but usually not lethal.
The ventral side highlights the Book lungs (round areas with slots on the bottom) where they breath and the Pectins (feather like) that are sensory organs thought to sense surfaces, vibrations and possibly chemoreceptors like female pheromones'.
