Yes, it is. (I read the topic, and I thought you meant the snail was eating the hermit, not the other way around).
There are at least 3 possibilities:
(1) The snail was dead, and the hermit was cleaning it out,
(2) The hermit was hungry, and decided to chase and eat the snail,
(3) The hermit needed a new shell, and decided to fight the snail over the shell.
