Making a Sea Anemone Using Smooth‑On Silicone


Any commercially available sea anemone that you would buy to use as an original model would not give the best representation of the sea creature. For the most realistic and unique representation, creating your own sea anemone using modeling clay is best. Sculpting this model is not as complicated a task as you might think. Proper positioning of the tentacles is key to attaining realism. 

Creating your own bulb-tip sea anemone offers several advantages:

  • Low-cost
  • Hyper-realistic
  • Lasts for many years
  • One-of-a-kind
  • Eliminates reef harvesting
  • Maintenance-free

In the step-by-step gallery below, you will learn how to make a bulb-tip sea anemone using Smooth-On mold making and casting materials.
