Four-ton shark swims in the Adriatic: crazy sighting in front of a seaside resort in Italy. Basking shark can filter around 1,800 tons of water per hour in this way; an adult animal needs up to 500 liters of zooplankton as food every day.
Experts from the Miramare Marine Reserve and the National Oceanographic and Geophysical Institute OGS unequivocally identified the animal based on its fins. The basking shark is the second largest known fish on earth after the slightly larger whale shark.
