Species sighted: Fin whale
Today’s sighting surprised us with three Fin whales, one at 17 meters, the other 2 smaller, at 14 meters. Fin whales feed on krill, tiny shrimp the size of a finger, they can eat up to 2 tons per day. They swallow large quantities of food-rich water in the mouth; with the help of the tongue, the water is expelled from the mouth and the baleen, a sort of large replacement filter for the teeth that retain food. The sighting is common in our sea since this species of whale lives permanently throughout the Mediterranean, constituting a separate population from that of the Atlantic Ocean. Fin whales – the second largest animal in the world – are able to “talk” to each other even several kilometers away, but their vocalizations are too low to be heard by the human ear.
