What is a planarian?
The definition of a Planarian is "any of various free-swimming, mostly freshwater flatworms of the class Turbellaria, having an undulating or sluglike motion: popular in laboratory studies for the ability to regenerate lost parts." This means that it can, if any body parts are chopped off, regrow them. In junior high we sliced it's head down the middle and it regrew two heads in a matter of weeks. Cool, but really disgusting. It is a worm-like animal. The definition of animal is "any such living thing other than a human being." So in conclusion, according to the definition of animal, a Planarian is an animal, but a very strange one.
What kind of asexual reproduction does a earthworm use?
Planaria are hermaphrodites, possessing both testes and ovaries. Thus, they can reproduce asexually with their own gametes or sexually with another planarian. In asexual reproduction, the planarian detaches its tail end and each half regrows the lost parts by regeneration. However several problems can occur with this, so this does not happen very often. Instead, in sexual reproduction, each planarian transports its excretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults. Sexual reproduction is desirable because it enhances the survival of the species by increasing the level of genetic diversity.
