Despite being widely studied, osmoregulator accumulation and their physiological role in plants submitted to saline stress is paradoxically little understood and quite a controversial phenomenon due to different results found in the literature.
Although the Hawaiian anchialine atyid Halocaridina rubra is a strong osmoregulator, its larvae have never been observed in nature.
