The Hissing Isopod, Armadillo officinalis, is a large defensive species from Greece, Spain and France. Their genus name, Armadillo (yes, that’s not a misspelling of Armadillidium!) is apt as they can ball up (conglobate) into a near-perfect sphere, completely sealed with all their legs and underside completely hidden. They tend to do this at the slight mention of danger and are often hesitant to unfurl for quite some time.

The common name of Hissing Isopod comes from their secondary defence of making a cicada-like sound, which is produced by rubbing their legs together in a circular motion on the inside of the shell. This sound is often produced by a group of them and if large enough can be quite a sound and heard from a few metres away.

This slow growing species reaches a size of 2 cm (0.8 in) and growing to full sizes takes about 9 months. This slow growth results in them living a long time, up to 9 years, the record for the longest living terrestrial isopod species.

As per many Mediterranean species they prefer a moist environment but should not be kept overly wet as too damp can result in issues with moulting. Though they can tolerate cooler; temperatures from 21 to 24°C (64 to 75°F), and  ample space encourages breeding.

These are Greece locality animals descended from wild collected stock.

Sold in a tub of 10.
