|---|---|
| Lifespan | 7–10 years |
| Juvenile Stage Ends | 24 months |
| Senior Age Threshold | 7 years |
| Exercise Needs | Low - slow continuous movement; explores enclosure at night |
|---|---|
| Grooming | None - maintain moist substrate; provide calcium sources; remove old food |
| Annual Exam Focus | Segment condition, leg movement coordination, mite check between segments, weight, coloration |
| Routine Care | Maintain 72-80°F; 70-80% humidity; fresh vegetables and leaf litter daily; calcium source always available; mist substrate |
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Mite Infestation | adult | very high | No | N/A |
| Dehydration | adult | high | No | N/A |
| Calcium Deficiency | adult | high | No | N/A |
| Bacterial Infection | adult | medium | No | N/A |
| Parasitic Nematodes | adult | medium | No | N/A |
| Molt Complications | juvenile | medium | No | N/A |
| Risk Level | Very Low |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Body segments should be evenly rounded; not shriveled between segments (dehydration sign); consistent diameter |
| Daily Activity | 3 minutes |
| Caloric Notes | Continuous access to leaf litter, vegetables, and calcium; self-regulates intake |
| Litter Size | 50–300 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | N/A |
| Neonatal Weight | 0.1–0.3 g |
|---|---|
| Growth Notes | Born with few segments; add segments with each molt; molt frequently as juveniles; slow growth to full size over 2-3 years |
| Vaccine/Health Schedule | No vaccines; maintain calcium availability; quarantine wild-caught for mites |
| Temperature | 22-27°C (72-80°F); moderate warmth |
|---|---|
| Humidity | 70-80%; moist substrate essential; mist daily; leaf litter layer |
| UVB Requirement | Not required; avoid direct light; nocturnal/crepuscular; ambient room lighting fine |
| Diet | Decaying leaf litter (primary), cucumber, sweet potato, apple, banana, cuttlebone/calcium powder supplement |
| Common Issues | Mites (extremely common), dehydration, calcium deficiency (soft exoskeleton), bacterial infections |
| Anxiety Proneness | Very Low |
|---|---|
| Top Triggers | Dry conditions, lack of calcium, bright lights, rough handling, vibrations |
| Separation Anxiety Risk | None |
| Calming Interventions | Moist dark environment, leaf litter coverage, group housing, minimal disturbance, calcium availability |
| Enrichment Needs | Varied leaf litter types, rotting wood, cork bark, deep substrate, vegetable variety, moss patches |
| Cognitive Dysfunction Risk | Very Low |
| Sociability Score | 4/10 |
| Locomotion | Slow continuous walking; burrowing into substrate; climbing low structures; coiling when disturbed |
|---|---|
| Social | Communal - can be kept in groups; often found resting together; no aggression; mutual tolerance |
| Comfort | Burrowed partially in substrate; coiled resting; slow exploration; feeding on leaf litter |
| Stress/Displacement | Tight coiling, defensive secretion (benzoquinones), refusing food, excessive burrowing, immobility |
| Breed-Specific | Largest millipede species (30cm+); gentle detritivore; communal; defensive chemical secretion (stains skin); excellent beginner invertebrate; long-lived |
| Types | None; completely silent |
|---|---|
| Frequency Range | N/A |
| Tendency | Very Low |
| Primary Modality | Primarily chemical (defensive secretions, pheromones); tactile (antennae); minimal visual |
| Tail/Body Signals | No distinct tail; posterior segments taper; anal segment condition indicates health; defensive coiling protects head |
| Top Problems | Defensive chemical secretion (stains/irritates), excessive burrowing, food selectivity |
|---|---|
| Medical Etiology | Soft segments (calcium deficiency); shriveling between segments (dehydration); mite clusters; lethargy |
| Fear/Anxiety Etiology | Tight coiling into spiral, chemical secretion, complete immobility |
| Frustration Etiology | Repeated climbing attempts on smooth surfaces, circling enclosure edges |
| Learned Behavior | Learns food placement locations; habituates to handling; recognizes moisture sources |
| Cognitive Dysfunction | Extremely limited; basic chemosensory navigation; food source memory |
| AI-Trainable Signals | Coiling tightness (stress level), movement speed (health), segment condition (hydration/calcium), chemical secretion |
|---|---|
| Context-Dependent Vocalizations | Coiling can be resting position OR defensive - handling context and secretion presence differentiate |
| Interspecies Communication | Very tolerant of handling; defensive secretion can stain/irritate skin; wash hands after; gentle disposition |
