Lepas anatifera

Microplastic Indicator

- 

In this article, Chaithanya M K highlights that Lepas anatifera is a barnacle commonly known as the goose barnacle. It is a biomonitor species, and because it is cosmopolitan, it is found almost everywhere. When subjected to gastrointestinal (GIT) testing, the species has been found to contain microplastics, which in turn indicates rising pollution levels in ocean and sea waters. These goose barnacles attach to floating plastic debris in the sea, as well as to drifting wooden logs. When they wash ashore, they indicate the presence of microplastics, cotton, cellulose, and other pollutants. For this reason, they are also called “dirt barnacles,” highlighting their unique ability to signal plastic and water contamination.

We humans have not only polluted the land with plastic but have also dumped enormous amounts of plastic and pesticides into the seas. Our growing greed has left almost no space untouched by waste. We often fail to understand the hardships animals face due to plastic pollution. Many turtles and aquatic species are dying because of microplastics. Plastic pollution threatens marine life through entanglement, ingestion, and chemical exposure, causing injury, starvation, and death. Microplastics disrupt the food chain and affect the health and reproduction of marine organisms. Therefore, we must act responsibly and allow other living creatures to thrive. Every nation must undertake microplastic assessments to reduce not only microplastics but all pollutants contaminating beaches, seas, and oceans.
