New records of jellyfish species in the Marmara Sea

AbstractThis manuscript reports the first observations of three species of Hydrozoa (Podocorynoides minima, Koellikerina fasciculata and Gastroblasta raffaelei) and one species of Scyphozoa (Discomedusa lobata) in the Marmara Sea that were sampled in 2006–2011. Their possible introduction pathways, some ecological and distributional details are briefly discussed here.
