## I have a backbone, 4 flipper-like legs, and a hard shell. I breathe air.

## Sea Turtle

## I have a backbone, fins, and scales. I have a long, smooth body, very sharp teeth. I swim fast and eat small fish.

## Barracuda

## I am a spiny-skinned animal, with a circular body shape. I eat algae on the reef. My long spines protect me.

## Long-spined sea urchin

## I am a jointed-led animal, with a hard, outside skeleton. I have 10 legs. I have 2 large antennae to defend myself. 

## Spiny lobster

## I belong to a group of unrelated animals that come in many shapes. You can only see me through a microscope. We drift through the waters. Some of us eat algae and others eat their own group.

## Zooplankton 

- Zooplankton

## Corals reproduce by releasing their eggs and sperm into the water. This is called

## Spawning 

- Spawning

## The sperm and egg joined together to form larvae is called

## Planulae 

- Planulae

## When a planula finally settles on hard substrate, it turns into a single

## Coral polyp

## One polyp divides to make 2 polyps, and each new polyp continues to divide, forming a 

## Coral colony

## Most corals spawn this many times during a year

## Once 

- Once

## The seaward facing slope of the reef is called

## Fore reef

## The highest and shallowest part of the reef is called

## Reef crest

## This type of coral grows in deeper water where less light is needed and has a flat shape on top

## Plate-like leaf coral

## On the reef crest types of coral can provide protection from strong storms and waves. This coral can also sting you if accidentally touched.

## Fire coral

## This coral can be found on the seaward side of the reef and looks more like moose antlers.

## Elkhorn coral

## This explosive material is sometimes used on reefs to capture fish

## Dynamite 

- Dynamite

## This material in the water can smother a reef or decrease the amount of light needed for coral growth

## Sediment 

- Sediment

## Mooring buoys are placed in the water to prevent this

## Anchoring on the reef

## Extremely high temperature waters may cause this to happen to coral

## Coral bleaching

## The removal of herbivorous fish will result in the overgrowth of this

## Algae 

- Algae

## The major fast-moving ocean current that runs close to Florida’s southeast coastal shore is called

## The Gulf Stream

## Not including the Florida Keys, these are the 4 counties where the southeast coral reef tract can be found

## Miami-Dade, Broward, Palm Beach, Martin

## Coral reefs in southeast Florida can be found as close as this many meters from shore

## 500 meters

## Coral reefs in South Florida generate this many dollars to the economy

## 2 billion

## These 2 coral species were listed as threatened on the endangered species list
