Someone named the dogfish on a lark;
Neither dog nor boney fish, it’s a shark;
It won’t fetch or roll over
Or answer to “Rover”
And its bite is far worse than its bark.

Sharks are completely boneless, as their bodies are made entirely of cartilage; hence “nor boney fish” above. Because sharks are almost impervious to cancer, researchers are studying shark cartilage to develop treatment for humans. Read more facts.
Please tell me you’re not doing “The Catfish” next.
Since you asked so nicely, Javier: The Catfish.
