Today we saw the rarest seal in the world! We explored the rugged coastlines of the Ilhas Desertas by Zodiac, marveling at towering cliffs and hidden caves. We went ashore to visit a scientific station working to protect the critically endangered Mediterranean monk seal. In an incredible moment, about half our guests spotted a wild monk seal — one of the rarest marine mammals on Earth. Later, north of the islands, Captain Leo found a pod of short-finned pilot whales, ending a remarkable day.
