We show in this paper that the dynamics of an Aurelia aurita polyps population can be modeled by the basic density-dependent logistic, or Verhulst, ordinary differential equation. A laboratory experiment was conducted on polyps of A. aurita attached to oyster shells collected in 2013 from the Port of Koper, Slovenia (North Adriatic Sea). The purpose of the present work is twofold: to study how the substrate availability may affect the growth of the polyps (and consequently of the jellyfish) population, and to propose an example for the classic logistic equation, both in high density (over the equilibrium) and in low density (under the equilibrium).
