Blackboard Tree

The Blackboard Tree (Alstonia scholaris) is a species in the genus Alstonia. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical dry broadleaf forests within the Oceanian biogeographic realm.

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.
