Anemone catching a copepod with one of its tentacles ; Cnidaires feed themselves by capturing small animals which pass near their tentacles. Those are covered with irritant capsules (Nematocysts) which kill almost instantaneously any individual who makes the error to pass very close to them or touch them, that is to say while swimming or by moving the waves. The projected microscopic filaments maintain the preys, then the tentacle deposit them in the mouth of the Cnidaire. Here Copepod is catched by a tentacle (dark part of the picture), the microscopic filaments are invisible on this scale.
