Jupiter Isopod (Cubaris sp.)

Cubaris sp. 'Jupiter'

The Jupiter Isopod (Cubaris 'Jupiter'). An Asian giant of the Cubaris family, considered the pinnacle of aesthetics for elite terrarium keepers (up to 0.7 inches). It literally resembles the planet Jupiter: very shiny and domed metallic graphite gray carapace, broken vertically by asymmetrical and fluid deep yellow or bright orange bands, and golden yellow lower skirts. Astronomical prices, very fragile to Asian humidity crashes, requires maniacal care and months to generate the first brood.

Species description

Geographical Origin and Habitat: Water-saturated undergrowths and karst tunnels invaded by epiphytic mosses in the deep Southeast Asia (Thailand).
Taxonomy and Genetics: Family Armadillidae. (Supreme design isopod). Species not yet scientifically classified (Cubaris sp.). It boasts a slightly larger size than the Rubber Ducky. It takes its name from the planet Jupiter due to the hypnotic pattern of its dorsal bands that resemble the gaseous storms of that world. The genetics of the coloration is unstable: some specimens ('Lemon Blue') turn strongly to neon blue/yellow.
Behavior and Habits: Hypogeal rock crystals. The behavior of the Jupiter is comparable to that of a motionless gem. They live in absolute darkness holed up in the belly of the moss and limestone. They detest sudden heat and escape direct light by diving in an instant into the wet mud and closing into a bite-proof sealed dome in which they remain locked even for a whole day.
Morphology: Total perfect enameled and shiny dome (Up to 0.7 inches / 1.8 cm). Unattainable aesthetic character: opalescent gray/black head (and not yellow like the Ducky), back furrowed by one or two very irregular and shaded deep yellow or sunset orange central bands (which cross the body diagonally or fused spots) and lateral 'skirts' (epimera) painted symmetrically of the same bright gold color.
