[1] Rhopalurus junceus can inhabit ecosystems ranging from savanna forests to semi-desert areas.

They are commonly found under rocks or fallen trees and throughout the epiphytic vegetation within the Bromeliads.

The body is yellowish brown, pink, orange, with a red or purple tail, a single stinger and the eight limbs darker, burgundy, purple or blackish, with a black triangle intercular.

[2] R. junceus has a life expectancy of three to five years, although lack of food results in only 15% reaching adulthood.

Escoazul or escozul (from escorpión azul - in Spanish: blue scorpion - the name by which it is known in Cuba) refers to a mixture used in Cuban traditional medicine as an anti-inflammatory.
