The rarest type of isopod known is the St. Helena Spiky Yellow Woodlouse, scientifically identified as Pseudolaureola atlantica. This extraordinary creature represents the pinnacle of isopod rarity, distinguished by its unique habitat and extremely limited geographical distribution.
Unique Characteristics and Habitat
This captivating isopod is a fascinating example of an arboreal species, meaning it lives high up in trees rather than on the ground. Unlike many common isopod species that inhabit leaf litter and damp soil, the St. Helena Spiky Yellow Woodlouse exclusively thrives within the canopies of the forests on the remote island of St. Helena.
Its life high above the forest floor, combined with its extremely restricted geographical range, makes it a uniquely specialized and exceptionally rare inhabitant of the island's ecosystem. The distinctive "spiky yellow" appearance further adds to its unique identity among isopod species, setting it apart as one of the most elusive and critically endangered terrestrial isopods known globally.
