Evaluation of microplastics ingested by sea cucumber stichopus horrens in Pulau Pangkor, Perak, Malaysia

The widespread presence of microplastics has caused significant concerns on their potential effects on marine ecosystems. Microplastics are classified as plastic products of less than 5 mm in size and are known to be one of the most dangerous aquatic debris to marine species. Sea cucumbers are dep...
