Chrysochromulina parva is a small haptophyte microalga belonging to the genus Chrysochromulina in the family Prymnesiaceae. The specific epithet parva (Latin: small) denotes its cell dimensions relative to other congeners. Structurally, cells possess two unequal flagella and a haptonema, the three-membrane-bound appendage that defines the class Haptophyta and provides the genus with its feeding and attachment capabilities. Organic scales cover the entire cell surface, and their ultrastructure is examined by electron microscopy for species identification. C. parva inhabits marine photic-zone waters in temperate and cold seas, where it forms part of the nanoplankton community. Haptophytes as a group contribute substantially to global marine primary production and produce significant quantities of dimethylsulfoniopropionate (DMSP), a compound with important implications for climate regulation via its atmospheric breakdown product dimethylsulfide. C. parva has not been formally assessed for conservation status and is listed as Not Evaluated by the IUCN. Like most free-living protists, it lacks the discrete geographic range limits that make conventional threat categorization applicable. Molecular surveys continue to expand knowledge of Chrysochromulina diversity in undersampled ocean regions.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
