Abstract: Ligia is the ancestor of terrestrial isopods, commonly known as rock lice or sea slater. The most species of this genus habitat at the high tidal zone located as a boundary between sea and land. The special biological role and its varying survival environment enable it to be high value on the research of biology and ecology. The present work reviewed its morphological structure characteristics, life habit and life history as well as ecophysiological studies, including water, food, light, temperature, salinity and osmotic pressure, oxygen and active substance.

Key words: Ligia, biology, ecophysiology
