| Risk Level | Very Low |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Body segments evenly filled; not shriveled; healthy sheen |
| Daily Activity | 4 minutes |
| Caloric Notes | Fresh fruits and vegetables daily; dry dog food as protein supplement |
| Litter Size | 20–60 |
|---|---|
| Dystocia Risk | Very Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | N/A |
| Neonatal Weight | 0.3–0.5 g |
|---|---|
| Growth Notes | Ovoviviparous (live birth); nymphs white at birth; molt 6 times over 6-7 months to adult size |
| Vaccine/Health Schedule | No vaccines; maintain clean conditions; avoid overcrowding |
| Temperature | 24-29°C (75-85°F); warm tropical conditions |
|---|---|
| Humidity | 50-70%; moderate humidity; water gel or moist cotton; ventilation important |
| UVB Requirement | Not required; nocturnal; avoid direct light |
| Diet | Fresh fruits (apple, banana, orange), vegetables (carrot, lettuce, sweet potato), dry dog food for protein |
| Common Issues | Mites (extremely common), dehydration, bacterial infections, overcrowding stress |
| Anxiety Proneness | Low |
|---|---|
| Top Triggers | Isolation from group, bright lights, dry conditions, overcrowding without hides |
| Separation Anxiety Risk | Low |
| Calming Interventions | Group housing, dark hides, consistent temperature, adequate food |
| Enrichment Needs | Vertical climbing surfaces, bark hides, egg crate layers, varied food, group dynamics |
| Cognitive Dysfunction Risk | Low |
| Sociability Score | 6/10 |
| Locomotion | Climbing vertical surfaces, nocturnal exploration, burrowing under bark/hides |
|---|---|
| Social | Highly social - colonial species; males establish dominance hierarchy; mutual antennation |
| Comfort | Clustered together under bark; antennae grooming; slow exploration; group resting |
| Stress/Displacement | Loud hissing, rapid movement, attempting to escape, isolation from group, refusing food |
| Breed-Specific | Famous for hissing sound (spiracle-based); wingless; colonial; male horn combat; excellent educational animal |
| Types | Disturbance hiss, male combat hiss, female attraction hiss, alarm hiss |
|---|---|
| Frequency Range | 2,000-10,000 Hz |
| Tendency | Medium |
| Primary Modality | Acoustic (hissing primary); chemical (pheromones); tactile (antennation) |
| Tail/Body Signals | No distinct tail; cerci at posterior; abdominal condition indicates health |
| Top Problems | Male-male horn combat, colony escape attempts, hissing at handling |
|---|---|
| Medical Etiology | Lethargy, loss of exoskeleton sheen, mite clusters, inability to climb |
| Fear/Anxiety Etiology | Loud disturbance hiss, rapid scatter, freezing, wedging into crevices |
| Frustration Etiology | Climbing walls, pushing at lid, increased male aggression, escape behavior |
| Learned Behavior | Associates lid opening with disturbance; learns food placement; recognizes colony members |
| Cognitive Dysfunction | Basic social learning; hierarchy recognition; food source memory |
| AI-Trainable Signals | Hiss type/intensity, antennae position, clustering behavior, horn posture (males) |
|---|---|
| Context-Dependent Vocalizations | Hissing varies by context: disturbance (sharp), combat (rhythmic), courtship (soft) |
| Interspecies Communication | Tolerates handling after habituation; hissing is defensive not aggressive; excellent educational animals |
