At the first time of Valladares’s artistic creation, the sea fauna was an important theme for his work. For example Cangrejo with a personal sign with the intention of not a mimetic representation, but it is a pretext of the artist to create a scene when the crab sees a shell with a pearl of silver. We can appreciate the overview for the relationship between the crab and the shell that express dynamism and movement; so that Valladares creates a singular work.
