On the bottom near the stcsmtopod den I noticed an aXgae-^covered clam 
shell that had the look of having been moved — the slit was distributed 
arouiKi its edges, I had the feeling that it might be a tiap-4oor or some- 
thing. And when I tried to turn it over it refused to tiim, and would snap 
back again into its original position. IThe reason for this peculiar behavior 
was the little crab who was using the shell for a bonnet. First one I have 
coH® across this year. When I carried him up to the boat he would raise his 
lid from time to time to see where he was being taken, I hope we can keep 
him in good condition until there is some sunshine so that we can remove his 
hat and watch him put it back on — observed by uy long lens. 
When we went out to the shooting area later in the day. — still no 
sun — we took the crab along, and some of the corbulaa for the lobster. 
That fellow was walking around on the sides of the enclosure when we arrived, 
probably feeling hollow in the stomach after two days with nothing to eat. 
After depositing the crab in another pen, I offered the lobster a couple of 
minnows. He took them from wb with gareat enthusiasm, hoistic^ them to his 
mouth with basket of lege. He tried to do the 8aa» thing with one of my 
fingers, but I discouraged this. I think he has teeth. 
At first he paid no attention to the corbulas — I offered him only 
one, actually — preferring minnow. But when there was no minnow he 
basketed the little clam and hoisted it to his Jaws, It disappeared, and 
a mon»nt later bits of shell floated to the bottom. Apparently the 
lobster has a working knowledge of how to eat clams. If he doesn't have 
teeth he has something that serves as a good substitute. I shall take
