Starfish Facts on Environmental Dangers and Threats

According to zoologists who study starfishes and their impact to the environment, these sea creatures have a very important role in the oceans.

The pollution caused by humans also affects these starfishes. When people pollute the waters, the contaminants in the water can get inside the bodies of the starfishes because of their vascular system. These starfishes do not have a good filtering system so oils and other pollutants can remain inside their systems and affect how they function.
