Balhuticaris voltae swam in the oceans of the Cambrian period approximately 506 million years ago.
At 24.5 cm (9.6 inches) long, the ancient animal is one of the largest Cambrian arthropods and the biggest bivalved arthropod known to date, with the closest being Nereocaris exilis and Tuzoia.
Balhuticaris voltae had an extremely elongated and multisegmented body bearing ca. 110 pairs of homonomous biramous limbs.
