Acanthonyx scutiformis, an endemic species in the Brazilian coast, is commonly found in intertidal rocky-shore algal communities. This study analyzes the population biology of A. scutiformis from Ubatuba region. A total of 371 specimens were collected

In this study we evaluated the types of algae chosen for decorating by the spider crab Acanthonyx scutiformis (Dana, 1851) and determined whether decorating is more common in juvenile or adult crabs and in females or males (adult). In field observations
