Theraphosa apophysis

🔤 Taxonomy

Theraphosa apophysis is the pinkfoot Goliath birdeater. It should be kept and bred separately from T. blondi and T. stirmi because trade confusion is common.

World Spider Catalog accepts the species and records the older combination Pseudotheraphosa apophysis. Juvenile color is useful as a clue, but provenance and molt records are safer than color alone when maintaining a breeding line.

English common names used in the hobby:

• Pinkfoot Goliath birdeater
• Pinkfoot goliath tarantula

📌 Description

Theraphosa apophysis is a New World tarantula kept mainly as a display invertebrate. Adult size is usually 10-12 cm body, 25-30 cm legspan, and lifespan is females 12-20+ years; males shorter after maturity. It should not be handled routinely. Even species considered calm can bolt, fall, bite, or flick urticating hairs when stressed. The keeper’s job is to provide a secure enclosure, stable moisture gradient, safe fall height, and enough privacy for normal feeding and molting.

Its urticating hairs can cause intense and repeated irritation, especially if they reach the eyes or airways. Wear gloves, long sleeves, and eye protection for disruptive work, keep the enclosure away from food-preparation areas, and damp-wipe nearby surfaces rather than sweeping hairs into the air.

🌍 Distribution

Northern South America, especially Venezuela; humid lowland forest, burrows, and damp ground retreats.

Captive care should turn that habitat context into secure retreats, stable warmth, clean water, and a workable moisture gradient.

Range notes are most useful when they explain how the animal finds cover, water, warmth, and safety; avoid turning them into sudden swings in the enclosure.

⚖️ Legal status

As checked against current official sources in April 2026, Theraphosa apophysis is not currently listed in the CITES Appendices, and no species-specific EU wildlife-trade Annex listing was found. It is not relevant to the Bern Convention unless a country applies separate native-wildlife rules. Local rules on ownership, import, sale, transport, breeding, invasive-species control, dangerous-animal licensing, and proof of lawful origin may still apply; keep purchase and breeding records.

🤌 Husbandry

Babies or slings should start in smaller secure enclosures such as secure small cup with damp lower substrate and cross-ventilation. Smaller starter housing makes feeding, molts, hydration, and waste easier to monitor. Adults need the full planned enclosure, stronger locks or lids, and more stable environmental zones. Do not buy a young animal unless the adult housing, food supply, and legal responsibilities are already realistic.

Juveniles may look different from adults and are often bought because of the pink-footed appearance. Keep growth records and molt notes, because identity, sexing, and maturity are easier to interpret when the history is not guesswork.

For adult animals, make the enclosure secure before making it decorative: firm lid, safe ventilation, stable water dish, deep substrate, and limited fall distance.

For spiderlings and juveniles, stability matters more than display. Keep the container small enough to locate prey and check molts, but include cover and a moisture choice so the animal is not forced to sit in the open.

House one animal per enclosure. A practical adult enclosure is 45 x 30 x 30 cm minimum; 60 x 45 x 45 cm with 15-20 cm substrate is better. Larger is useful when it creates more usable movement, better gradients, and safer maintenance. Use secure ventilation and stable furnishings. Keep simple notes on feeding, molts, weight changes, and behaviour, and quarantine new animals before adding them to the collection.

For a new arrival, use a simple enclosure and separate tools for at least 60-90 days. Record feeding, drinking, feces, molts, and any mites; do not move used substrate or decor between enclosures. Imported animals may arrive dehydrated, so give darkness, a full water dish, and a stable retreat before offering a large meal.

Plan every opening before unlatching the enclosure. Keep a catch cup, rigid card, and long tongs within reach, close the room door, and work from the side rather than directly above the spider. Routine care should mostly mean refilling water, removing prey remains, and spot-cleaning; full substrate changes are reserved for contamination, persistent pests, or enclosure failure.

💡 Lighting

A clear 10-12 hour day-night cycle is useful. Ordinary room light is enough for tarantulas; UVB and bright basking lamps are unnecessary. Avoid visible night lights and any lamp that dries the enclosure or overheats retreats.

🌡 Heating and temperature

Aim for 24-27 °C with no direct hot lamp. Measure with digital probes and use an infrared thermometer for any warmed surfaces. Any supplemental heat should be controlled by a thermostat. Tarantulas are usually safer with warm room temperatures or gentle side heat rather than hot lamps or under-tank pads.

💧 Humidity and water

Humidity target: 75-85% with a large water dish and ventilation that prevents stagnant wet air. Keep fresh water available in a stable dish sized for the animal. The enclosure should have moisture choices without becoming wet and stale. Both bone-dry conditions and soaked substrate can create problems.

Maintain moisture by pouring water slowly along one or two enclosure walls so the lower substrate stays damp while part of the surface can dry. Check the substrate by appearance and feel rather than repeatedly spraying to meet a hygrometer number. Condensation that persists all day, sour odor, or widespread mold indicates too much water, insufficient ventilation, or both.

🌿 Enclosure and decoration

Provide a warm retreat, cooler retreat, water, safe texture for molting, and enough cover that the animal can move without feeling exposed. Juvenile setups should be simple enough to inspect but not bare. Adult enclosures must be built for strength, stable furniture, secure doors or lids, and safe cleaning access. Limit fall height for heavy terrestrial tarantulas. Use deep substrate, keep open space modest, and make sure lids, ventilation panels, and access points close securely.

🪳 Feeding

Feed large roaches, crickets, locusts, and occasional worms; vertebrate prey is unnecessary. Use the abdomen and recent molt or feeding history to judge meal size, not appetite alone. Spiderlings eat smaller meals more often; adults usually eat less often and should stay lean rather than swollen. Remove uneaten prey promptly, especially before a molt.

After a molt, wait until the fangs are fully dark and the spider moves normally before feeding: usually several days for a juvenile and at least 7-10 days for a very large adult. Prey that burrows should be disabled or offered in a smooth-sided dish so it cannot remain hidden beside a soft spider.

🥚 Breeding

Breeding is specialist work. Pair only robust adults, supervise introductions, and prepare for many individually housed spiderlings. Breeding should use healthy mature animals with known identity and lawful origin. Keep dates, pairings, offspring numbers, and transfer records, and do not produce more young than can be housed and placed responsibly.

🩺 Common problems

Common problems include dehydration, bad molts, overheating, mites, fall injuries, refusal to feed with visible weight loss, and stress from exposure or poor security. Warning signs include a shriveled abdomen, leaking injury, failed molt, swollen joints, twisting posture, sudden lethargy, or repeated frantic escape attempts. Consult an exotic-animal veterinarian for severe weakness, injury, swelling, failed molt, or prolonged refusal to feed with decline in body condition.

Food refusal by itself is common before a molt. First remove live prey, confirm the water dish is full, compare the abdomen with earlier photos, and check both temperature and lower-substrate moisture. Never dig out a spider that has sealed its retreat unless flooding, collapse, or another immediate hazard makes intervention necessary.

📌 Conclusion

Theraphosa apophysis needs adult-sized planning from the start, not only interest in the juvenile stage. Secure housing, measured conditions, appropriate feeding, and basic records make long-term care predictable.
