Eight-meter-long basking shark spotted in the Gulf of Trieste. Researchers see this as good news for the biodiversity of the region.
Such an animal is said to have been last seen in the region around Trieste in 2015. Basking sharks are considered the second largest known fish on earth. Their special anatomy allows them to filter out food and in this way catch plankton, animal and plant organisms floating around in the water. The animals, which occur in cold to moderately warm waters in both hemispheres, are endangered by commercial fishing.
