Blue star

The Blue star (Amsonia orientalis) is a species in the genus Amsonia. It is currently classified as Critically Endangered on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Protoperidinium subinerme is a marine heterotrophic dinoflagellate with a robust, armored cell body and relatively short spines. It inhabits coastal and neritic oceanic waters across temperate and subtropical seas globally. This predatory protist engulfs diatoms and other phytoplankton cells using pallium feeding, making it an important component of microbial food webs.
