Hapalotremus major (Urubamba Giant)

Hapalotremus major (Urubamba Giant)

The Urubamba Giant is a specialized, high-altitude species from the Urubamba River valley in the Peruvian Andes. While “Giant” is part of its name, it is a giant only in comparison to its smaller relatives in the Hapalotremus genus. It is a rugged, cold-adapted tarantula prized by collectors who enjoy montane species with a stocky, powerful build.

Key Highlights

• Rugged Appearance: This species features a dense, velvety coat of copper, bronze, and charcoal hairs. Under bright light, the cephalothorax often displays a subtle metallic luster, contrasting beautifully with its thick, muscular legs.

• High-Altitude Specialist: Hailing from the Andes, it is biologically adapted to cooler, thinner air. It is much hardier in lower temperatures than most tropical tarantulas but is conversely very sensitive to heat.

• Sturdy Build: It is a heavy-bodied terrestrial species. While it only reaches a medium leg span of approximately 10–12 cm (4–5 inches), its thick proportions give it a very formidable and “solid” presence.

• Temperament: They are known for being bold and somewhat “feisty” for a New World species. Rather than bolting, they are often willing to stand their ground and give a threat posture if they feel cornered.
