Whistling Tarantula (Selenocosmia Crassipes)

If you’re after raw power and old-world attitude, look no further. Selenocosmia crassipes is a giant burrowing species from Australia known for its deep, resonant “whistle” when disturbed. Lightning-fast, defensive, and incredibly strong — this spider is like the heavyweight champion of Aussie tarantulas.

Quick Facts

Common Name: Whistling Tarantula / Queensland Whistling Spider

Scientific Name: Selenocosmia crassipes

Origin: Northern and eastern Australia (Queensland, Northern Territory)

Size: 8–9 inches (20–23 cm) leg span

Lifespan:

• Females: 20–30 years
• Males: 5–8 years

Temperament: Defensive, extremely fast, prone to biting when provoked

Coloration

Earthy tones — brown, tan, and charcoal

Heavy-bodied, thick legs with fine, dense hair

Built more like a tank than a typical tarantula — very robust

Housing & Care

Enclosure Type: Deep burrowing terrestrial

Substrate: 8–10 inches of compactable substrate (topsoil/coco fiber/clay mix)

Humidity: 65–75% — keep the lower levels moist

Temperature: 75–85°F (24–29°C)

Decor:

• Deep starter burrow or hide — it will expand it massively
• Minimal surface decor — focus on deep, stable substrate
• Large water dish — crucial for hydration

These spiders create impressive tunnel systems. Expect deep burrows and major landscape changes.

Feeding

Diet: Large roaches, crickets, and even small locusts

Feeding Schedule:

• Slings: 2–3x/week
• Juveniles: Weekly
• Adults: Every 7–10 days

Brutal takedowns — powerful jaws, fast strike

Why It's a Legend

One of the largest and most robust tarantulas

Known for stridulation — it can “hiss” audibly when disturbed

Incredibly strong — can move heavy decor and rearrange entire enclosures

Impressive predator behavior and fascinating burrowing habits

Long-lived with proper care

Notes

Not a beginner species — defensive, fast, and with a medically significant bite (painful!)

Needs deep, stable substrate to prevent stress

Very reclusive — will spend most of its time underground

Handling is absolutely not recommended

Secure enclosure is a must — powerful enough to push lids if not locked down properly
