Meet the Parrotfish.

The colors of the Parrot Fish will change several times over the course of their lifespan. But their mouths look like they are always grinning.

They are generally social creatures and travel in schools of 40 fish. If the dominant male dies in the pack, one of the females will change gender and color and become the alpha male

They are named after a bird because their fused teeth looks just like a beak.Their teeth are good for scraping algae and coral.

But sunbathers beware.

Much of the white sand on tropical beaches is former parrotfish feces. After the fish digest the algae and coral rock, it's excreted as sand

A dead lionfish floats in the water, as its greenish blood is seen in the background, after it was speared by Mexican dive master Martin Vera off the reefs of Cozumel February 11, 2011. Native to Indo-Pacific waters, lionfish have invaded the Caribbean because of the aquarium trade and are gobbling up native species but have no predators in the region, so their population is exploding.

A lionfish swims in the "Chichiriviche de la Costa" beach in the state of Vargas outside Caracas July 25, 2010. Six lionfish, which are native to the Indian Ocean, were accidentally released into the Caribbean in 1992, when an aquarium in southern Florida was destroyed by Hurricane Andrew. Lionfish, which are believed to threaten native marine wildlife in Venezuela and the livelihoods of coastal towns dependent on fishing and tourism, have since been detected in at least 30 locations across the country since July 2010, triggering alarm among experts.
