Pterinochilus Murinus: The African Green Baboon Tarantula

Introduction

Pterinochilus murinus is a species of tarantula native to the arid regions of southern Africa, primarily found in countries such as South Africa, Namibia, Botswana, and Zimbabwe. This tarantula is known for its striking emerald-green coloration, a distinctive feature that sets it apart from other tarantula species.

Physical Characteristics

• Size: Adult P. murinus typically measure between 6-10 centimeters (2.4-4 inches) in body length, with a leg span of 15-20 centimeters (6-8 inches). Females are generally larger than males.
• Coloration: P. murinus is instantly recognizable by its vibrant green coloration, which can range from deep emerald to bluish-green. The legs and abdomen are typically a darker green, while the carapace (head and thorax) is a lighter shade.
• Hair: P. murinus tarantulas have sparsely distributed urticating hairs on their abdomen. These hairs can be released as a defense mechanism when threatened.

Behavior and Habitat

• Behavior: P. murinus is a burrowing species that creates underground burrows lined with silk. They are typically nocturnal and prefer dry, arid environments. Adult males may wander in search of mates during the breeding season.
• Habitat: P. murinus is found in various arid habitats, including deserts, savannas, and grasslands. They prefer areas with loose, sandy soil suitable for burrowing.

Venom and Toxicity

• Venom: P. murinus venom is primarily composed of neurotoxins, which target the nervous system.
• Toxicity: The venom of P. murinus is generally considered to be mild to moderately toxic to humans. Bites typically cause local symptoms such as pain, swelling, and nausea. In rare cases, severe allergic reactions or respiratory distress may occur.

Care and Maintenance in Captivity

• Enclosure: P. murinus tarantulas require a terrestrial enclosure with adequate space for burrowing. A minimum enclosure size of 10 gallons is recommended.
• Substrate: The substrate should be a mixture of sand, loam, and peat moss to provide a suitable burrowing environment.
• Temperature and humidity: Optimal temperatures range between 75-85°F (24-29°C). Humidity levels should be kept relatively low at around 30-50%.
• Feeding: P. murinus tarantulas are opportunistic predators that primarily feed on insects and small vertebrates. Crickets, roaches, and mealworms are common feeder insects.
• Handling: While P. murinus tarantulas are generally not aggressive, they can be skittish and may bite if provoked. Handling should be kept to a minimum and done with caution.

Breeding

• Mating: Breeding occurs during the summer months. Males will wander in search of females and perform a courtship dance to attract them.
• Egg sac: The female will lay her eggs in a silken egg sac, which she will guard until the spiderlings emerge.
• Spiderlings: The spiderlings will typically emerge from the egg sac after 6-8 weeks. They will molt several times as they grow and reach adulthood in around 2-3 years.

Conservation Status

P. murinus is not currently considered to be an endangered or threatened species. However, habitat loss and degradation due to human activities may pose potential threats to their populations in the future.

• Observe the tarantula's behavior to identify any potential health issues.
• Handle the tarantula gently to avoid causing stress.

Step-by-Step Approach to Caring for Pterinochilus Murinus

1. Set up the enclosure: Ensure the enclosure meets the size and environmental requirements of the tarantula.
2. Provide a burrowing environment: Add a deep substrate and provide a hideout for the tarantula to burrow into.
3. Regulate temperature and humidity: Use a heating pad or lamp to maintain optimal temperatures and a hygrometer to monitor humidity levels.
4. Feed the tarantula: Offer a diet consisting of live insects or small vertebrates at regular intervals.
5. Handle the tarantula carefully: Use caution when handling the tarantula and minimize handling to avoid stress.
6. Monitor the tarantula's health: Observe the tarantula for any signs of illness or stress and seek veterinary assistance if necessary.

Conclusion
