Marianina rosea is a small species; eleven measured specimens ranged from 4 to 11mm in length. This is a common species in the Marshalls, with many specimens observed on lagoon reefs and pinnacles of Enewetak, Kwajalein, Ujelang, and Rongelap Atolls. They typically live under dead coral rocks at depths of 1 to 5 meters and are frequently found paired.
