And while it does create balance, sometimes these relationships among species are not equally advantageous to the species involved. Interestingly, the boxer crab also shares a similar relationship with sea anemonesit feeds the anemone and, in exchange, makes use of its stinging tentacles as a defense mechanism or deterrent.
