Mature females display longitudinal bands on the upper part of their bodies, extending from the head to the tail.

[4] C. arubensis typically grow to a length of approximately 15 centimetres (5.9 in)[5] Whiptails (Teiidae) possess femoral pores, although they are larger in males compared to females.

[6] One of the notable adaptations observed within the Teiidae family of lizards is the transition to herbivorous diets in various endemic island species.

[7] The diet of Aruba whiptails encompasses both insects and predominantly plant material such as flowers, nectar, leaves and fruits.

During the mating season, which occurs from September to October, mature male C. arubensis lizards undergo a transformation.

[11] Both C. arubensis and C. murinus display an increased likelihood of tongue-flicking (briefly extruding the tip of their bifurcated tongue for approximately 100 milliseconds) in the presence of quinine compared to its absence.
