Desiccation Resistance of Intertidal Crevice Species as a Factor in their Zonation

Abstract

The fauna of the intertidal crevice habitat displays 2 types of zonation littoral zonation from high water to low water, and internal zonation from the inside to the outside of the crevice. Desiccation experiments, in moving air, were conducted to learn if any correlation existed between resistance to desiccation and zonation. The species used were selected to represent animals from various tidal levels, and belonged to different ecological types.
