Chrysochromulina scutellum is a marine haptophyte microalga belonging to the family Prymnesiaceae. The species epithet scutellum (Latin: small shield) describes the shield-like shape of the distinctive scales adorning the cell surface. These organic scales, produced internally in Golgi-derived vesicles and subsequently exported to the plasma membrane, form a protective and taxonomically informative outer coat. Cells are biflagellate with a haptonema, allowing both swimming and temporary attachment to solid surfaces or prey organisms. C. scutellum is found in coastal and offshore marine environments, with documented records from northern European seas. Haptophytes of the Chrysochromulina type are photosynthetic nanoflagellates that utilize chlorophylls a and c, fucoxanthin, and related pigments for light harvesting. The DMSP produced by many haptophytes, including Chrysochromulina species, is a critical component of the marine sulfur cycle and acts as an antioxidant, cryoprotectant, and grazing deterrent. C. scutellum has not been formally assessed by the IUCN and is categorized as Not Evaluated. Understanding the true geographic and genetic diversity of this species and its congeners requires expanded environmental molecular surveys.

Epaulard

O maior membro da família dos golfinhos, as orcas (Orcinus orca) podem atingir até 9 metros de comprimento e 6 toneladas, sendo encontradas em todos os oceanos, do Ártico ao Antártico. Predadores de topo que vivem em grupos matrilineares com dialetos distintos, estratégias de caça e tradições culturais que diferem entre populações. Algumas populações se especializam em peixes, outras em mamíferos marinhos. Sem predadores naturais, as orcas ocupam o topo de todas as cadeias alimentares marinhas que habitam.
