## Basic Information
| Field | Value |
|---|---|
| Species | Invertebrate |
| Origin | Madagascar |
| Size Category | Small |
| Scientific Name | Gromphadorhina portentosa |
| Husbandry Difficulty | Beginner |

## Vital Statistics
| Metric | Value |
|---|---|
| Weight Range | 0.02–0.025 kg |
| Lifespan | 3–5 years |
| Puppy/Kitten Stage Ends | 6 months |
| Senior Age Threshold | 3 years |

## Puppy/Kitten Development
- **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 Schedule**: No vaccines; maintain clean conditions; avoid overcrowding

## Adult Preventive Care
- **Exercise Needs**: Low - active climbers; nocturnal exploration
- **Grooming**: None - maintain substrate; provide fresh food daily
- **Annual Exam Focus**: Exoskeleton condition, horn size (males), leg integrity, mite check
- **Routine Care**: Maintain 75-85°F; 50-70% humidity; fresh fruits/vegetables daily; water gel; spot clean weekly

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Mite Infestation | adult | very high | No | No |
| Dehydration | adult | high | No | No |
| Bacterial Infection | adult | medium | No | No |
| Molt Complications | juvenile | medium | No | No |
| Wing Bud Deformity | juvenile | low | No | No |
| Overcrowding Stress | adult | medium | No | No |

## Obesity Management
- **Risk Level**: Very Low
- **Ideal BCS**: 3/9
- **Visual Cues**: Body segments evenly filled; not shriveled; healthy sheen
- **Daily Activity Target**: 4 minutes
- **Caloric Formula**: Fresh fruits and vegetables daily; dry dog food as protein supplement

## Breeding & Genetics
- **Litter Size**: 20–60
- **Dystocia Risk**: Very Low
- **CHIC Required Tests**: N/A
- **Recommended DNA Tests**: N/A

## Behavioral Ethogram
- **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

## Vocalization Baseline
- **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 Signals**: No distinct tail; cerci at posterior; abdominal condition indicates health

## Emotional Wellbeing
- **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
- **Cognitive Dysfunction Risk**: Low

## Behavior Problems (Six-Etiology Classification)
- **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

## AI Communication Decoding
- **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

## Husbandry Environment
- **Temperature Gradient**: 24-29°C (75-85°F); warm tropical conditions
- **Humidity Range**: 50-70%; moderate humidity; water gel or moist cotton; ventilation important
- **UVB Requirement**: Not required; nocturnal; avoid direct light
- **Diet Type**: Fresh fruits (apple, banana, orange), vegetables (carrot, lettuce, sweet potato), dry dog food for protein
- **Common Health Issues**: Mites (extremely common), dehydration, bacterial infections, overcrowding stress
