Predation by endothermic fish. (a) Pop-up locations for the tags consumed by endothermic fish, coded by predator type and origin. Grey lines indicate the 1000 m bathymetry contour. BoB = Bay of Biscay, GoSL = Gulf of St. Lawrence, IrS = Irish Shelf, IS = Irminger Sea, and LaS = Labrador Shelf. (b) Depth (black) and temperature (red) profiles for a tag consumed by an Atlantic bluefin tuna in the Gulf of St. Lawrence. (c) Depth (black) and temperature (red) profiles for a tag consumed by a porbeagle in the Northwest Atlantic Ocean. (d) Depth (black) and temperature (red) profiles for a tag consumed by an endothermic fish in the Northeast Atlantic Ocean. Yellow points indicate values distorted by the tags, blue vertical lines indicate time of ingestion and expulsion, and grey areas indicate night. Tag ID and temporal resolution of time series data (Δt) are stated above plot panels, and the corresponding Tag IDs are also indicated in panel a.
