Ctenophores are gelatinous marine invertebrates that prey upon zooplankton. The two main ctenophoran orders that affect planktonic communities are the Cydippida and the Lobata. The Cydippida possess two elongate tentacles. In the Lobata, two large lobes surround comparatively reduced tentacles, and water is drawn through the inter-lobe space by four flap-like ciliated auricles. Both groups are successful predators and are widespread in the world's oceans (1). In coastal regions, members of the genera Bolinopsis (Lobata) and Pleurobrachia (Cydippida) may co-occur and often reach high densities simultaneously.
The co-occurrence of Bolinopsis and Pleurobrachia ...
