Knifing is a behaviour whereby a shark swims directly at the surface with its dorsal fin out of the water. While this behaviour has been reported in a number of species, information on the frequency and timing of such behaviour could provide insights on how sharks use the ocean–atmosphere interface. Our analysis of the timing of the reception of satellite(More)
BACKGROUND Over recent decades jellyfish have caused fish kill events and recurrent gill problems in marine-farmed salmonids. Common jellyfish (Aurelia spp.) are among the most cosmopolitan jellyfish species in the oceans, with populations increasing in many coastal areas. The negative interaction between jellyfish and fish in aquaculture remains a poorly(More)
A combination of dissection and computed tomography scanning has provided significant novel insights into the structure and function of the Dermochelys coriacea larynx and its associated muscles. Several previously unknown features of the laryngeal aditus (glottis) are described and their functional significance in its opening and closure are considered.(More)
Although red tides are typically formed by dinoflagellate blooms, aloricate ciliates in the genus Mesodinium also produce striking red blooms throughout the world. In mid-March 2015, we confirmed the occurrence of dense blooms of Mesodinium major in Lough Hyne Marine Nature Reserve, a fully marine sea lough in County Cork, SW Ireland. Daytime aggregations(More)
