the point of attacliment of the muscle and the ventral tube is less 

 than the length of the tentacle ; but this difficulty is at once 

 avoided by the presence of a second muscle, which throws the 

 retracted tentacle into a curve. Moreover, the muscles are already 

 greatly extended when the tentacle is protruded to its full length, 

 but must have been much more so if there had only been a single 

 muscle.
