LAUSR

A minimum of twenty porbeagles Lamna nasus were observed circling the Alba oil platform (UK North Sea) over several days in in July 2014. Although schools of fish often aggregate around oil platforms, less is known about their ability to aggregate pelagic sharks and L. nasus are rarely seen at the surface. This unusual observation provides new insights into L. nasus behaviour and habitat use and the potential role of offshore artificial structures on pelagic predators.
