Goliath Birdeater

**Goliath Birdeater** — The world's heaviest tarantula by mass and arguably the most impressive invertebrate in the hobby. Requires very high humidity (80–90%) and deep moist substrate. Possesses Type III urticating hairs — the most irritating kind — that can become airborne and cause significant skin and respiratory irritation. Stridulates (produces a hissing sound) as a warning. Large fangs capable of delivering a painful bite even if not medically significant. Requires large enclosure, frequent feeding, and experienced handling only. Not recommended for beginners. A stunning but demanding species.
