“The main problem facing any kind of studies on solifuges is the keeping of these animals in captivity. So far, nobody has successfully reared them in a laboratory. It is even difficult to keep them a short time (e.g., two weeks) in captivity. Most of the Namibian species died after a couple of days after they had been captured. The Argentinean species survived a maximum of about two weeks in captivity. The eremobatid species, captured in Arizona (USA) survived in general for about a week. The galeodid species from Kazakhstan survived a slightly longer period up to a couple of months, which could implicate, that these animals are less susceptive regarding e.g., differences in temperature. All solifuges independent the country where they were collected became lethargic after a couple of days and did not show any kind of a natural behavior any more.” – Anja Elisabeth Klann, Histology and Ultrastructure of Solifuges
