Arctic lemming

The Arctic lemming (Dicrostonyx torquatus) is a species in the genus Dicrostonyx. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

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.
