Perkinsea

Perkinsea is a group of single-celled, eukaryotic organisms that belong to the larger group called protists. They are mostly aquatic and often play roles in the ecosystem by infecting and harming various aquatic animals, such as shellfish and fish, sometimes causing diseases. While some Perkinsea are harmless, others can be significant pathogens, impacting wildlife health and aquaculture. They are characterized by unique cellular features and share evolutionary ties with other protist groups, making them important for understanding the diversity and dynamics of microbial life in aquatic environments.
