In 3 days ~40% in a week ~70%
Hurter's spadefoot toad or Hurter's spadefoot (Scaphiopus hurterii) is a species of American spadefoot toad (family Scaphiopodidae) found in the south central United States (Texas, Louisiana, Arkansas, Oklahoma); its range might extend to the adjacent northern Mexico. It was once classified as a subspecies of the eastern spadefoot toad (Scaphiopus holbrookii), but it has been granted its own species status. The specific name hurterii is in honor of the Swiss-American naturalist and curator of the St. Louis Academy of Sciences, Julius Hurter. Wikipedia →
