The Northern krill, Meganyctiphanes norvegica (Crustacea, Euphausiacea) is widely distributed in the northern and northeastern parts of the Atlantic Ocean where it faces rapid variations in water temperatures and food. We studied the physiological potential of krill to compensate for environmentally induced metabolic changes. Two isoforms of the glycolytic key enzyme pyruvate kinase (PKI and PK...

Sound is an effective channel for the transfer of information underwater. While it known that fish and whales can use sound communication, as a cue to localise predators prey, much less about production in invertebrates. Here we describe sounds produced by two most common marine crustacean zooplankton Northern hemisphere: krill (Meganyctiphanes norvegica) copepods (Calanus spp.). The recorded w...
