| Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate the impact that these organisms may have on local populations, biodiversity, and ultimately on the functioning of food webs. In the Mediterranean Sea, little is known about the dynamics of alien jellyfish, despite this biodiversity hotspot being one of the most threatened areas by increasing numbers of alien jellyfish. Here, we investigated the population dynamics and predatory impact of a non-indigenous scyphomedusa, Aurelia solida Browne 1905, in the Bizerte Lagoon, Tunisia. The study was based on bimonthly surveys performed over two consecutive years, from November 2012 to August 2014. Field observations showed that the planktonic phase of A.... |

Cassiopea frondosa and C. xamachana are carnivorous. Prey are filtered from the water by the pumping activity of the umbrella. Prey, predominantly small epibenthic crustaceans (0.2- 10 mm in length) are caught mostly by interception. However, some prey may impact on the oral surface through turbulence or by their own locomotion. Prey capture was essentially the same for both species, except that the vesicles take an active part in prey capture only in C. frondosa. Ingestion occurred after the digitate-fringed lips of the funnel-shaped oral ostia opened. The digitata... |

| Most of the scyphozoans and cubozoans recorded for the Brazilian coast are presumed to be distributed over the entire coastline, but little information on precise records is available. This paper presents the first published records for the Ceará state (northeastern region) of the cubozoan Chiropsalmus quadrumanus, and the scyphozoans Chrysaora lactea, Linuche unguiculata (polyp), Lychnorhiza lucerna, Nausithoe sp. (polyp), Phyllorhiza punctata, and Stomolophus meleagris. The medusoid species have been known by local fishermen and non-specialists for a long time in the area. |
