Numerous terrestrial and marine organisms, including cephalopods, are capable of light emission. In addition to communication, bioluminescence is used for attraction defense mechanisms. The present review aims to: (i) updated information on the taxonomic diversity luminous cephalopods morphological features, (ii) describe large-scale biogeographic patterns, (iii) show research trends over last ...

Cephalopods are pivotal components of marine food webs, but biodiversity studies hampered by challenges to sample these agile molluscs. Metabarcoding environmental DNA (eDNA) is a potentially powerful technique study oceanic cephalopod and distribution has not been applied thus far. We present novel universal primer pair for metabarcoding cephalopods from eDNA, Ceph18S (Forward: 5?-CGC GGC GCT ...
