Porcellio expansus “Orange Tortosa” is a striking giant Porcellio species admired for its large size, powerful antennae, and vibrant orange colouring. Native to southern Spain, this morph originates from the Tortosa region and is prized by collectors for its bold appearance and impressive presence in the enclosure.

As one of the larger Porcellio species, P. expansus are active and often visible exploring their habitat. They thrive in well-ventilated setups with a clear moisture gradient, deep organic substrate, and plenty of bark hides. With stable conditions and regular feeding, they can establish strong colonies and become a standout species in any isopod collection.
