Abstract: The inflated catch tentacle of Metridium senile behaves independent of the oral disk. Close observation during aggression toward Anthopleura elegantissima reveals clues to its hydrostatic and neural separation from the rest of the animal. In the development of the catch tentacle from regular tentacle, changes in cnidom, musculature, and nerve net are necessary to make it a functional unit.
