In 2014, a pod of pilot whales was found floundering in perilously shallow water off the shore of Florida in the US. Forty or fifty short-finned whales remained close to a narrow shoreline—choosing not to swim out to the deeper waters, where they would be safe. Several of the blackfish were ill, which caused conservationists to worry. Pilot whales are intensely loyal creatures, and when one in their group is sick or in jeopardy, the rest of the pod simply will not leave. They form a circle and stay close together.
