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.

Orca común

El mayor miembro de la familia de los delfínidos, la orca (Orcinus orca) puede alcanzar hasta 9 metros de longitud y 6 toneladas de peso, y se encuentra en todos los océanos desde el Ártico hasta el Antártico. Es un depredador apex que vive en grupos matrilineales con dialectos distintos, estrategias de caza y tradiciones culturales que difieren entre poblaciones. Algunas poblaciones se especializan en peces, otras en mamíferos marinos. Sin depredadores naturales, las orcas ocupan la cima de todas las cadenas tróficas marinas que habitan.
