This is the first recorded observation of Akashiwo sanguinea excreting mucilaginous substances from pores on the cell surface. Observations were from samples collected in the Caloosahatchee Estuary, Florida, USA during a bloom event, with densities of 672 cells $mL^{-1}$ of A. sanguinea, including 51 cells surrounded by mucous. Scanning electron microscopy observations revealed that the mucous was secreted from thecal pores on the cell surface. The potential significance of mucous production is discussed.
