Species of crustacean
Haplophthalmus danicus, also known as the terrestrial cave isopod or spurred ridgeback isopod, is a species of woodlouse in the family Trichoniscidae. It is naturally found in Europe, Southern Asia, and temperate Asia, however it has been introduced to North America.[1][2][3][4] This species was likely introduced during original European settlement, and therefore has been well established in terrestrial communities.[5]
