Bubble-tip Anemone vs Tube Anemone: common questions
Is the tube anemone a true anemone like the bubble-tip anemone?
No, despite a broadly similar appearance, the tube anemone belongs to an entirely separate taxonomic order from true sea anemones like the bubble-tip anemone, a distinction supported by real biological differences such as its unique tube-building silk.
Which of these two builds a tube, the bubble-tip or the tube anemone?
The tube anemone, which constructs its tube using specialised threads called ptychocysts, a type of stinging cell found nowhere else in nature; the bubble-tip anemone builds no comparable structure.
Which anemone hosts clownfish, the bubble-tip or the tube anemone?
The bubble-tip anemone, which hosts more clownfish species than any other anemone on the reef, while the tube anemone does not serve as a clownfish host.
