Thai Silver Earth Tiger Tarantula for sale from Big Z's (Ornithoctonus costalis). Spice-rated keeper notes, care guidance, and live-arrival packing where eligible.
No warning hairs, no bluff: just speed and a bite it will use
Ornithoctonus costalis, the Thai Silver Earth Tiger, is a fast, defensive Old World fossorial out of the lowland forests of Thailand and Myanmar, in the same Ornithoctoninae group as the Cobalt Blue and the Asian earth tigers. Silvery-grey and built low and coiled like the dedicated burrower it is, adults stretch a serious 5 to 7 inches of legspan. It disappears into a tunnel of its own making, then explodes out of it when the mood turns.
Never handle this one. Old World tarantulas carry no urticating hairs to flick as a warning, so any defensive display is a straight bite risk, and bite reports for this group describe serious pain, swelling, and joint stiffness lasting days. Give it deep, moist, compactable substrate to tunnel through, strong cross-ventilation, and a snug starter burrow, then step back and let it work. This is an Extreme, Spice 5 keeper's animal, gorgeous and unforgiving: read the care guide for the enclosure build and the safety rules before it comes home.
The numbers live in the care guide. Enclosure size, temps, humidity, feeding schedule, premolt signs, handling boundaries: it's all in the care guide for this exact fella. Start with the full Advanced guide, or click for the quick Open the Simple version →
