Viola Beach showed a higher incidence of individuals, due to the greater availability of food and greater local biodiversity. As a result, the species Bunodosoma caissarum showed the highest incidence during the survey, with a total of 321 individuals collected, while the species Anthopleura cascaia showed the lowest incidence, as only 4 individuals were catalogued in the region studied.
