Telodeinopus assiniensis, commonly known as the Satin Millipede, is a medium-to-large species native to the warm, humid forests of West Africa (specifically regions like Ghana and Togo). It is highly regarded in the hobby for its glossy appearance and docile, beginner-friendly nature. 
 
Physical Appearance & Size
Appearance: Characterized by a "satin" or smooth shine. Its body features alternating dark brown to chocolate and cream, yellow, or orange rings.
Legs: The legs are typically lighter than the body, often appearing beige, whitish, or slightly pink.
Size: Adults reach an impressive length of 15–16cm. 
 
Care & Habitat Requirements
Temperature: Maintain a range of 22–26°C (72–79°F). Precise temperatures (up to 28°C) are often necessary for successful breeding.
Humidity: Requires high humidity levels of 80–90%. The enclosure should be misted regularly, and the substrate should remain damp like a wrung-out sponge.
Substrate: A deep substrate (at least 10–15cm) is vital for burrowing. A mix of leaf humus, white rotten wood, and dried leaves is recommended.
Diet: They are detritivores. While they primarily eat their substrate, they should be offered supplemental fresh vegetables (like cucumber or sweet potato) and calcium (cuttlefish bone) for exoskeleton health. 
 
Behaviour
The Satin Millipede is a "quiet giant"—peaceful and sociable, making it possible to house multiple individuals together provided there is enough space. They are primarily nocturnal, burrowing during the day and emerging at night to forage.
