Oceaniidae

Oceaniidae is a family of marine hydrozoans belonging to the order Anthoathecata. These jellyfish are characterized by their distinct life cycles, often involving both a polyp stage and a medusa stage. The polyps are typically sessile and colonial, while the medusae are free-swimming. Members of the Oceaniidae family are found in various marine environments, from coastal waters to the open ocean, and exhibit a wide range of sizes and appearances. Their diet usually consists of small planktonic organisms, which they capture using their tentacles. Reproduction in Oceaniidae can be sexual or asexual. The family includes several genera, each with its own specific characteristics and distribution. While some species are well-studied, others remain less understood, highlighting the ongoing research into marine biodiversity. The ecological role of Oceaniidae varies depending on the species and its habitat, but they generally contribute to the marine food web as both predators and prey.
