[2] This species is found in shallow waters in the Indo-Pacific where it lives on the seabed, rocks and corals.
These are tubular extensions of the wall of the column and on their upper side there are a few semi-spherical bulges known as vesicles.
[3] Triactis producta is found in shallow waters of the tropical Indo-Pacific Ocean, its range extending from the Red Sea and Mozambique to Hawaii and French Polynesia.
[3] Boxer crabs in the genus Lybia have developed a mutualistic relationship with small sea anemones such as Triactis producta.
The crab's front limbs have modified chelae, each of which can gently grip a sea anemone by its column, and it usually holds one in each claw.
In one reported case, these lasted for several weeks and were accompanied by a pigmented, blistered lesion and prolonged skin sensitivity.
