Examples of Cnidarians
Here are 10 examples of cnidarians:
1. Jellyfish (class Scyphozoa)

5. Corals (class Anthozoa)
Corals are another type of sessile cnidarian. They are known for their ability to build reefs, which are important marine ecosystems. Coral reefs provide habitat for a wide variety of marine life, and they also help to protect coastlines from erosion.
6. Hydras (class Hydrozoa)
Hydras are small freshwater cnidarians. They have long, slender bodies and tentacles that are arranged around their mouths. Hydras are carnivores and feed on small aquatic animals.
7. Fire corals (class Hydrozoa)
Fire corals are a type of coral that has a venomous sting. Their stings can be painful to humans, and they can cause severe skin irritation.
