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.
What is bleeding from the ear? Bleeding from the ear is ear drainage that contains blood. The discharge may be a combination of pus, wax, fluid and blood. Although there are other possible causes, the most common cause of bleeding from the ear is a ruptured or perforated eardrum.
There can be many causes of bleeding. Bleeding can occur from injuries to the external canal such as a scratch, Q-tip injury or insect bite. Infections can cause bleeding when an infected cyst drains or the eardrum ruptures from a middle ear infection.
