Theraphosa stirmi spiderling • 1 1/2″ (burgundy goliath birdeater)

Description

Theraphosa stirmi was the last of the 3 Theraphosa described: Theraphosa blondi (1804), Theraphosa apophysis (1991), and Theraphosa stirmi (2010).

T. stirmi isn’t the ‘goliath birdeater.’ That name belongs to T. blondi. Rather, T. stimi is the ‘burgundy goliath birdeater.’ Seems to be a source of confusion.

But maybe the confusion is understandable: For over 10 years T. stirmi was sold mistakenly as T. blondi. Closer examination in 2008 led to scientific description in 2010 [1]. Native to southeast Guyana [1], T. stirmi is rainforest creature. It thrives in warmth and humidity.

By far the most important factor in raising Theraphosa spiderings is humidity. Use slightly dampened substrate (1 part water + 10 parts dry substrate) and limit ventilation enough to allow humidity to build.

As your pet grows you’ll find it tolerates a wider range of conditions. We prefer dryer substrate and continued elevated humidity.

Care highlights:

• slightly dampened substrate +/- water dish to support humidity
• elevated humidity (80-95%), adjust ventilation as needed
• room temperature (68-72F) up to 80F
• consider hide, forest litter and plantings for enrichment
