inexorable wolf spider

The "inexorable wolf spider" (Hogna inexorabilis) is a critically endangered species of wolf spider found only on Deserta Grande in the Madeira Islands. Wolf spiders belong to the family Lycosidae and are known for their wolflike hunting style, chasing prey rather than trapping it in webs. These spiders are widespread, with many species found in various ecosystems, including north of the Arctic Circle.123

Wolf spiders are typically dark brown, hairy, and have stout legs. They are easily identified by their eight eyes, arranged in three distinct rows. Most species live in silk-lined tubular nests in the ground and are active hunters, often roaming in search of food. Female wolf spiders exhibit maternal care, carrying their egg sacs attached to their bodies and allowing their young to ride on their backs after hatching.1
