Shiro Utsuri Isopod (Cubaris sp.)

Cubaris sp. 'Shiro Utsuri'

The Cubaris 'Shiro Utsuri'. A colossal and spectacular elite isopod (0.7 inches) whose name and livery are inspired by the famous Japanese Koi carps ('Shiro Utsuri' = black and white). This Cubaris features a waxy and very shiny milk white or diaphanous cream shell, heavily and irregularly spotted with ink black, dark gray and sometimes peach dotted patches. It is a rustic but demanding animal, which requires huge quantities of calcium and calcareous forest terrariums to maintain the grandeur and enameling of the high contrast carapace.

Species description

Geographical Origin and Habitat: Captive selection derived (or related) from Asian wild strains that inhabit the deep karst undergrowth and lethal tropical rotting mud.
Taxonomy and Genetics: Family Armadillidae. (The Dalmatian / Koi Cubaris). An exclusive mutation/selection of an undescribed giant Cubaris. If the Panda King divides colors into sharp blocks, the Shiro Utsuri is the triumph of random piebaldness ('Cow' or 'Koi' pattern). No two specimens are identical, making it one of the most collectible isopods in the world for morph hunters.
Behavior and Habits: Underground ceramic dairy cows. While maintaining the massive dimensions of the Pallasii or Jupiter, the Shiro Utsuri are incredibly voracious and much more active on the surface than other Asian Cubaris. If the box is pitch dark, they swarm to the surface to devour zucchini and krill, forming heaps of hungry spotted 'ceramic cows'. If disturbed they flee quickly and instantly conglobate into marble balls.
Morphology: Total enameled very shiny and armored dome (Over 0.7 inches / 1.8 cm). Majestic thick ceramic carapace. Entirely shiny milk white background, or pale opalescent cream, randomly flooded by asymmetrical and extensive patches of solid black (Ink black) or smoke gray color on the back and sides. They literally look like polished Carrara marble pebbles or large round Koi carps without water.
