In 2000, the nominal—on a live weight basis—total landings of all Adriatic fisheries reached 110,000 tonnes (108,000 long tons). [247] Overfishing is a recognised problem—450 species of fish live in the Adriatic Sea, including 120 species threatened by excessive commercial fishing, a problem exacerbated by pollution and global warming .
The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow rostrum, bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.
The Mediterranean Cetacean Migratory Corridor was established by Spain in 2018 under the aegis of the UN Environment's Mediterranean Action Plan (MAP). It is a major route in the seasonal migration of cetaceans, particularly fin whales, between the African coast (wintering site) and the northern Mediterranean (summer feeding and breeding site).
Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [23] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [24] In some whales, however, it is less than half that of humans: 0.9% versus 2.1%.

Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
Some 277 fish species have been introduced to Europe, and over one-third of Europe's current fish fauna is composed of introduced species, [19] whereas more than a third of Europe's freshwater fish species are at risk of extinction, according to new data released by the World Conservation Union (IUCN).
The authors estimated that the genome-wide sequence similarity between beluga whales and killer whales is 97.87%. [ citation needed ] The beluga's earliest known distinctive ancestors include the prehistoric Denebola brachycephala from the late Miocene epoch (9–10 million years ago), [ 20 ] [ 21 ] and Bohaskaia monodontoides , from the early ...
