<c><1>Squid
<l><5>A file-like radula rams food down the throat 
<l><5>and esophagus, which passes directly through  
<l><5>the brain to the stomach. As an invertebrate, 
<l><5>a squid has no bones. A feather-shaped blade,
<l><5>or gladius, helps support the body and serves
<l><5>as a site for muscle attachment. It is made of
<l><5>chitin, like your fingernails. Cartilage 
<l><5>(tough, gristle-like tissue) surrounds a squid's 
<l><5>brain. The ink congeals into a squid-like shape
<l><5>that holds the enemy's attention while the 
<l><5>squid turns pale and jets away.
