Snails and Slugs learn more about names for this taxon. Scientists aim to describe a single 'tree of life' that reflects the evolutionary relationships of living things. However, evolutionary relationships are a matter of ongoing discovery, and there are different opinions about how living things should be grouped and named. EOL reflects these differences by supporting several different scientific 'classifications'. Some species have been named more than once.

Ear canal injury: The ear canal is covered by skin and like skin anywhere else in the body will heal when it is injured.
