A mermaid is a figure in early mythology and blah blah blah YOU KNOW THIS ALREADY!
Mermaids have cartilage, similar to the bones in your ear, in their tails. Which that is why you don't see mermaid skeletons with their tails. Mako mermaids and h2o:just add water is FAKE. You don't get a pretty little light to sheild you from spectators (mocking voice). You don't get 9 frickin' powers from a pretty little necklace. As a mermaid, you can't talk to animals. BYE BEFORE I GET KILLED BY MAKO MERMAIDS AND H2O: JUST ADD WATER FANS!!!!!!!!!!!!!!
I will now go hide in a hole.
