Have you heard of the Coelacanths? They are considered to be a "living fossil" because they were thought to be extinct for millions of years, but then people started finding them - a few at a time - in the Indian Ocean. Coelacanths are enormous - for a fish as they are about six feet long. One of the most unexpected things about them - other than the fact they still live in our oceans today, is the moms are pregnant for five years! Yes, FIVE years!
