Borneo Isopod (Cubaris sp.)

Cubaris sp. 'Borneo'

The Cubaris 'Borneo'. A large armored and shy jewel isopod from the asphyxiating caves of the Asian island. Very similar in titanic proportions to a Jupiter, but it sports a less lively and more monolithic livery, of a dark anthracite gray or lead black, embellished at the lower edges and on the head by a spectral golden yellow-cream. Robust but dependent on advanced rotting wood and very high humidity, it is an animal of absolute darkness and Elizabethan isolation terrariums.

Species description

Geographical Origin and Habitat: Lethal unexplored jungles, rotting asphyxiating karst caves and muddy sediments of the island of Borneo.
Taxonomy and Genetics: Family Armadillidae. (Giant Shadow Isopod). It belongs to the mutations/species related to the large Asian two-tone Cubaris but deviates from the fluorescent brilliance preferring mournful shades and mineral mimicry. Darker than the Pak Chong, more homogeneous than the Shiro Utsuri, the Borneo is a purist of slate gray that vanishes into calcareous sediments.
Behavior and Habits: Terrified curled lead ingots. Clumsy but incredibly peaceful and introverted. It develops entire colonies assembled in the lower part of a soggy piece of wood, slowly feeding on the fetid lichens. When surprised by the light, it falls playing dead, snapping shut into an impenetrable ceramic circle to defend itself from the predators of the rainforest.
Morphology: Immense total enameled dome (Up to 0.7 inches / 1.8 cm). Titanic shell for a Cubaris (Jupiter dimensions). The background is a deep Lead Black or very dark shiny Smoke Gray. No extravagant neon colors, but austere elegance: the extreme bands of the body (rear, head and low skirt) are bathed in an Antique Yellow nuanced in cream white, giving the illusion of opaque golden edges that do not break the Asian majesty.
