Monocentropus balfouri (Socotra Island Blue Baboon)

Communal species

Old World Terrestrial Baboon

Not a beginner species



  • It is a beautiful specie with blue legs from the tibia down, on a sand body.

  • This tarantula will also build an extensive web tunnels in the enclosure.

  • This baboon is not shy, but will stay out in view during the day and is a very hardy species. 

  • They make excellent parents.

  • This is a must have baboon. 


  • 24°-27°C humidity at 60-65% 


  • This is a opportunistic burrower. As a spiderling, use a vial that would allow at least 7cm of substrate for burrowing. As sub-adult-adult I use a terrarium that will allow at least 10cm of substrate.


  • Place a bark for a starter burrow hide. 

Food Consumption:

  • Feed slings twice a week.

  • Feed adults once a week.

  • Food size should be the size of the carapace. 

  • This species is a good eater. 

Water Requirements:

  • Keep a water dish in the tank.

  • Keep the substrate in the terrarium dry.

  • Every four months wet one side of the substrate, than allow it to dry out.

Growth Rate: 

  • The growth rate of this species is medium.

  • Adult leg span 12.7cm.


  • For a Old World tarantula, the Blue Baboon has a forgiving nature.

  • They are more likely to beat a retreat than confront its opponent as an adult, but spiderling and juveniles will stand their ground with a threat pose.
