Oncaea [Oncaea]

Description

Oncaea is one of the most well-known genera within the family Oncaeidae, featuring a broad diversity of species. These copepods exhibit a spherical to slightly elongated body shape, with adaptations that allow them to thrive in various marine habitats, from coastal zones to the deep sea. Oncaea species are crucial in aquatic ecosystems, preying on smaller plankton while themselves being prey for larger organisms, thus facilitating energy transfer through the food web.
