1. Your temps are lower than what is recommended or required?
Scorpions are ectothermic. Ectotherms have increased metabolic rates at higher temperatures (Schulte 2015). Higher metabolism means increased mobility to search for food and mates, which corresponds to increased fitness (Knies and Kingsolver 2010).
Because ectotherms’ internal temperatures are contingent upon the environment.
On average, scorpions experience a near-tripling of metabolic rate for a 10°C increase in temperature (see also Bridges et al., 1997), but the precise extent of this increase varies widely among individuals.
2. The scorpion's food intake is capped?
Scorpions have low resting rates of aerobic metabolism; typically only 25% of many other terrestrial arthropods (Anderson 1970; Lighton et al. 2001). This, combined with a low activity sit-and-wait or slow search predatory style, means that total energy expenditures are small. The result is that scorpions are able to endure periods of low food availability and to convert a large portion of their food into biomass or progeny (Lighton et al. 2001). In some arid ecosystems scorpion biomass may exceed that of all vertebrates combined (Polis & Yamashita 1991).
