You look for an anomaly on the ocean - white caps when there are no other white caps or movement in the water. That often is Dolphins. Tom Eckles photographed a pod headed north and moving fast!
Here are two close-ups of a Risso's Dolphin, taken by Ron LeValley. Risso's Dolphins feed on Squid. The older the dolphin is, the more scratches it has on its body. The scratches are caused by their interaction with other dolphins and from the squid they hunt. These dolphins are also called Grampus.
Thanks to Tom and to Ron for allowing me to share their photos with you here. To see more of Ron's nature photography, here is his website: http://levalleyphoto.com/home/ and to see more of Tom's photography, here is his website: www.tomeckles.com
