Specific Examples Of Cnidarians

Upsidedown Mangrove Jelly Fish (Cassiopea Xamachana)- These jellyfish are almost never ever found alone. It grows up to the size of a plate and are usually eaten by ocean sunfish and leatherback sea turtles. It also uses its bell to stick to the seafloor.

Fringing Coral Reef - one of the three main types of reefs. They are the most common type and they grow around the coastline near islands and continents. Human impact has decreased the amount of fringing coral reefs.
