| Visual Cues | Rounded but not bloated; defined tail base; active movement |
| Daily Activity | 20 minutes |
| Caloric Notes | Earthworms (staple), crickets, waxworms; feed every 2-3 days; 2-3 items per feeding |
| Litter Size | 100–1000 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | N/A |
| Neonatal Weight | 0.5–1 g |
|---|---|
| Growth Notes | Aquatic larval stage 2-5 months; metamorphosis to terrestrial; some remain neotenic; adult size 12-18 months |
| Vaccine/Health Schedule | No vaccines; quarantine; test for ranavirus in new animals |
| Temperature | 15-22°C (60-72°F); avoid temperatures above 24°C |
|---|---|
| Humidity | 60-80%; moist (not wet) substrate; large water dish for soaking |
| UVB Requirement | Not required; 12h light cycle; avoid bright direct lighting |
| Diet | Earthworms (primary), crickets, waxworms, occasional pinky mice for large adults; dust with calcium |
| Common Issues | Skin infections, ranavirus, MBD in juveniles, obesity, parasites |
| Anxiety Proneness | Very Low |
|---|---|
| Top Triggers | High temperatures, dry substrate, excessive handling, bright lights |
| Separation Anxiety Risk | None |
| Calming Interventions | Moist cool substrate, hides, consistent environment, gentle handling |
| Enrichment Needs | Burrowing substrate, varied terrain, water dish for soaking, leaf litter, cork bark hides |
| Cognitive Dysfunction Risk | Very Low |
| Sociability Score | 4/10 |
| Locomotion | Walking, burrowing, swimming (if aquatic morph), climbing low structures |
|---|---|
| Social | Can cohabitate with similar-sized individuals; may eat smaller animals; generally peaceful |
| Comfort | Burrowing in moist substrate, soaking in water dish, exploring at night |
| Stress/Displacement | Excessive hiding, refusing food, skin dryness, attempting to escape |
| Breed-Specific | Largest terrestrial salamander in North America; some populations remain aquatic (neotenic); hardy; personable; long-lived |
| Types | Squeaking when handled (rare), no significant vocalizations |
|---|---|
| Frequency Range | N/A - minimal vocal communication |
| Tendency | Very Low |
| Primary Modality | Chemical (pheromones), visual (body posture, color), tactile |
| Tail/Body Signals | Thick tail stores fat reserves; tail can be autotomized (dropped) if grabbed; regenerates |
| Top Problems | Escape attempts (strong diggers), obesity if overfed, substrate ingestion |
|---|---|
| Medical Etiology | Skin dryness from low humidity; lethargy from high temperatures; MBD causing soft bones |
| Fear/Anxiety Etiology | Burrowing to hide, tail thrashing, releasing cloacal contents; rarely bites |
| Frustration Etiology | Digging at enclosure walls; climbing corners; escape attempts |
| Learned Behavior | Recognizes feeding time; hand-feeding possible; some individuals become quite tame; food-motivated |
| Cognitive Dysfunction | Minimal; consistent friendly temperament; long-lived with stable behavior |
| AI-Trainable Signals | Activity level, skin moisture/condition, feeding response, burrowing patterns |
|---|---|
| Context-Dependent Vocalizations | Increased burrowing may be normal OR temperature stress - check ambient temperature |
| Interspecies Communication | Most personable salamander species; hand-feeds readily; recognizes keeper; tolerates gentle handling; excellent beginner species |
