exif: {"Image DocumentName": "Locomotion in Fish Fish that can swim are known as nekton", "Image ImageDescription": "Streamlined shape helps fish swim faster. Temperature affects speed. Cold water = slower speed. Nekton as opposed to plankton (which just drift or float on the surface) Some fins help stabilize fish. Fish sometimes have venomous spines in their dorsal fins (lionfish) Fusiform shaped fish are tapered at both ends. Fastest fish = sword fish, tuna, dolphin fish (mahi mahi), barracuda. Cold water = lower metabolic rate = slower swimming. Some fish have been able to develop a way to save the heat their muscles generate. This heat keeps metabolism up and can keep moving fast despite cold water.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
