Hermit Crabs. Elevate themselves high on their legs and use their enlarged chelae to shovel onto a quick stride once to their mouth when it is assisted only the smell. Lateral helps. They do this rapidly several times and then crawl over the ground keeping on scratching it. They evidently feed on small ground living animals and dead organic substances. As usual with crabs they are very alert holding their eyes and antennae well out in front but not wary protruding out of the shell. The constant shoveling and crawling habits of the chelae evidently gives them their enlarged girth. In others the enlargement of all the limbs may be due to carrying about the large and heavy Natric shells. Soft-shelled turtle, very active, good swimmer with their extended feet an action. Can pull down considerably the posterior surface skin to close tail again. Head long and snout like like a saw-pike.
