A mnemonic device is a rhyme or phrase that helps you remember an important date, or list of items. One you may be familiar with is "In 1492, Clolumbus sail the ocean blue." A mnemonic device for taxonomy used by generations of biology students is "Kings play chess on fine green sand." These words in this nonsensical sentence begin with the same letters of the taxa listed from largest to smallest.
In the space provided, invent two mnemonics of your own for the seven taxa.
