Researchers at the University of Alicante's Marine Laboratory have discovered and formally described a new jellyfish species named Copula lucentia in the Mediterranean Sea. The species was found in waters off El Campello, Alicante, Spain, and measures only a few millimeters in size. The discovery was documented in 2024 and demonstrates that the Mediterranean still harbors undescribed marine species.


This discovery highlights the incomplete nature of marine biodiversity inventories even in well-studied regions like the Mediterranean Sea. The finding underscores the importance of continued marine research and monitoring to document and understand the full extent of ocean life, which is essential for conservation efforts and understanding ecosystem dynamics.


The Mediterranean Sea still holds species unknown to science. One of them is Copula lucentia, a tiny jellyfish measuring just a few millimeters. Discovered off El Campello, in Alicante, it was formally described in 2024 by a research team at the University of Alicante (UA) Marine Laboratory in Dénia, which forms part of the university’s Ramón Margalef Multidisciplinary Institute for Environmental Research.
