The predator-prey interactions among aquatic organisms is an interesting part of the natural world which has not been seen much in computer animation. This paper explores the interaction between various sea anemones and the starfish Dermasterias imbricata. Although a simulation between a specific sea anemone, Stomphia coccinea to Dermasterias imbricata was created, an approach was taken such that different anemones can with minor parameter changes be used to replace S. coccinea. The animation was created using a parametric keyframe approach of procedural models. The anemone and starfish were modeled using the Blob Tree. The implicit model within the system is defined as a hierarchical composition of multiple objects. Using a hierarchical construction of the model, we can refine the model locally and deform it globally while maintaining the integrity of surface details.EngComputer Scienceunknown2001-679-0210.11575/PRISM/31216
