While the large baleen whales are often the highlight of whale watching cruises, their smaller cousins, dolphins, often steal the show. On most whale watching cruises, we encounter groups of 50 or more common dolphins. These playful and energetic dolphins often ride the bow and wake of the boat. Occasionally, we see a stampede of common dolphins porpoising at high speed in the same direction. Porpoising is a much more efficient and faster way for dolphins to travel since the animals experience much less drag (resistance) in air than water. Why do dolphins stampede? They may be traveling towards a large ball of schooling fishes to feed. Often, the cause is a mystery. Whatever the cause, a dolphin stampede is always a thrilling experience!
