We were treated to a large school of Atlantic spotted dolphins (Stenella frontalis) socialising, mating, jumping and enjoying themselves in the bow wave during the morning tour. Bottlenose dolphins (Tursiops truncatus) rushed past the scenery at top speed. However, we were able to observe them up close again later on. It is very impressive to see how big and powerful this dolphin species is.
Dolphins are remarkable swimmers that impress with their speed and manoeuvrability in the water. Some dolphin species can reach speeds of up to 60 km/h. These high speeds are due to their streamlined physique and strong musculature. Dolphins use their powerful tail to propel themselves, while their pectoral fins are used for steering. The structure of the skin supports the efficiency of their locomotion. It is smooth and supple. This reduces water resistance, making it easier to glide through the water. Some dolphins can swim even faster for short distances, for example when fleeing predators or hunting prey. Another fascinating aspect of their speed is their ability to swim synchronously in groups, which is useful for both hunting and defence. Scientists have discovered that dolphins are able to coordinate their movements through complex communication and social structures, maximising their efficiency in the water.
At midday we saw another school of Bottlenose dolphins, but they were now very relaxed and in resting mode. There were also Atlantic spotted dolphins filling their
little bellies with fish.
