Dendronotus iris feeding behaviour

Concerning message #16629:

Hi Bill:
Concerning the "small?" animal down in the anemone tube - this is quite common. After locating a tube anemone with its tentacles extended the slug rears up and back and attacks the anemone rapidly and hard (see Nudibranch Behavior, pg 96). Almost everytime, the anemone retracts back into the tube, pulling the slug in also. The slug stays within the tube and usually wins the tug of match by continuing to chew on the anemone until it succumbs. Amazing behavior, quite exciting to watch.
