Dolphins

Dolphins are cetacean mammals closely related to whales and porpoises. There are almost forty species of dolphin in 17 genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb) (Maui's dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 long tons; 11 short tons) (the orca or killer whale). They are found worldwide, mostly in the shallower seas of the continental shelves and are carnivores, eating mostly fish and squid. The family Delphinidae, the largest in the order Cetacea, evolved relatively recently, about ten million years ago during the Miocene.

Blue Whale

The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). At 30 metres (98 ft) in length and 190 tonnes (210 short tons) or more in weight, it is the largest existing animal and the heaviest that has ever existed.

Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill.

Southern Right Whale

The southern right whale (Eubalaena australis) is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena. Like other right whales, the southern right whale is readily distinguished from others by the callosities on its head, a broad back without a dorsal fin, and a long arching mouth that begins above the eye. Its skin is very dark grey or black, occasionally with some white patches on the belly. The right whale's callosities appear white due to large colonies of cyamids (whale lice). It is almost indistinguishable from the closely related North Atlantic and the North Pacific right whales, displaying only minor skull differences. It may have fewer callosities on its head and more on its lower lips than the two northern species. Approximately 10,000 southern right whales are spread throughout the southern part of the Southern Hemisphere.

Sei Whale

The sei whale  Balaenoptera borealis, is a baleen whale, the fourth-largest rorqual after the blue whale, the fin whale and the humpback whale. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. It avoids polar and tropical waters and semi-enclosed bodies of water. The sei whale migrates annually from cool and subpolar waters in summer to winter intemperate and subtropical waters.

Marsaxlokk, Malta

Marsaxlokk is a traditional fishing village located in the south-eastern part of Malta, with a population of 3,499 people (March 2013). The village’s name comes from marsa, which means "port" and xlokk, which is the local name for south east. The word is related to the name for the dry sirocco wind that blows from the Sahara, comparable to the equivalent Catalan word, "xaloc". The village is known for the Marsaxlokk Market, a large market which takes place around the whole village on Sundays and tourist market all days during the week. The inhabitants of the village are called the Xlukkajri and are historically fishermen. It was in the "Golfo dello Scirocco" (Xlokk's bay) that the first Phoenicians landed and set up trading posts on Malta, during the ninth century BC. During the Great Siege of Malta, Marsaxlokk harbor was also used as an anchorage by the Turkish fleet.
Overlooking the northern arm of Marsaxlokk Bay is the hill of Tas-Silġ, which contains remains of megalithic temples of the Tarxien phase, with later alterations resembling the Ħaġar Qim model. Bronze Age material has also been found scattered around the area. From the end of the 6th century BC to the 1st century AD, the hill was used as a religious site, notably as a temple dedicated to Astarte/Hera. Marsaxlokk was part of Żejtun in the past years. The Tas-Silġ site was used again for religious purposes sometime in the 4th century AD, when it was adapted to a new religion, Christianity, and possibly used as a monastery.

Minke Whales

Minke whale, or lesser rorqual, is a name given to two species of marine mammal belonging to a clade within the suborder of baleen whales. The minke whale was given its official designation by Lacepède in 1804, who described a juvenile specimen of Balænoptera acuto-rostrata. The name is a partial translation of Norwegian minkehval, possibly after a Norwegian whaler named Meincke, who mistook a northern minke whale for a blue whale. Taxonomists further categorize the common minke whale into two or three subspecies; the North Atlantic minke whale, the North Pacific minke whale and dwarf minke whale. All minke whales are part of the rorquals, a family that includes the humpback whale, the fin whale, the Bryde's whale, the sei whale and the blue whale. The junior synonyms for B. acutorostrata are B. davidsoni (Cope 1872), B. minimia (Rapp, 1837) and B. rostrata (Fabricius, 1780). There is one synonym for B. bonaerensis - B. huttoni (Gray 1874). Writing in his 1998 classification, Rice recognized two of the subspecies of the common minke whale - B. a. scammoni (Scammon's minke whale) and a further (taxonomically) unnamed subspecies found in the Southern Hemisphere, the dwarf minke whale (first described by Best, 1985). On at least one occasion, an Antarctic minke whale has been confirmed migrating to the Arctic. In addition, at least two wild hybrids between a common minke whale and an Antarctic minke whale have been confirmed.

Fin whales

The fin whale, also called the finback whale, razorback, or common rorqual, is a marine mammal belonging to the suborder of baleen whales. It is the second largest animal after the blue whale, growing to 27.3 metres (89.5 ft) long and weighing nearly 74 tonnes (73 long tons; 82 short tons). The American naturalist Roy Chapman Andrews called the fin whale "the greyhound of the sea... for its beautiful, slender body is built like a racing yacht and the animal can surpass the speed of the fastest ocean steamship." Long and slender, the fin whale's body is brownish-grey with a paler underside. At least two recognized subspecies exist: the North Atlantic and the Southern Hemisphere. It is found in all the major oceans, from polar to tropical waters. It is absent only from waters close to the ice pack at the poles and relatively small areas of water away from the open ocean. The highest population density occurs in temperate and cool waters. Its food consists of small schooling fish, squid, and crustaceans including copepods and krill. Like all other large whales, the fin whale was heavily hunted during the twentieth century and is an endangered species. Over 725,000 fin whales were reported taken from the Southern Hemisphere between 1905 and 1976, as of 1997 survived by only 38,000. The International Whaling Commission (IWC) issued a moratorium on commercial hunting of this whale, although Iceland and Japan have resumed hunting. The species is also hunted by Greenlanders under the IWC's Aboriginal Subsistence Whaling provisions. Global population estimates range from less than 100,000 to roughly 119,000.

Sperm whales

The sperm whale is the largest of the toothed whales and the largest toothed predator. It is the only living member of genus Physeter, and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. Mature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length. The sperm whale feeds primarily on squid. Plunging to 2,250 metres (7,380 ft) for prey, it is the second deepest diving mammal, following only the Cuvier's beaked whale. The sperm whale's clicking vocalization, a form of echolocation and communication, may be as loud as 230 decibels (re 1 µPa at 1 m) underwater, making it the loudest sound produced by any animal. It has the largest brain of any animal on Earth, more than five times heavier than a human's. Sperm whales can live for more than 60 years. The sperm whale can be found anywhere in the open ocean. Females and young males live together in groups while mature males live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators. Calves and weakened adults are taken by pods of orcas. From the early eighteenth century through the late 20th, the species was a prime target of whalers. The head of the whale contains a liquid wax called spermaceti, from which the whale derives its name. Spermaceti was used in lubricants, oil lamps, and candles. Ambergris, a waste product from its digestive system, is still used as a fixative in perfumes. Occasionally the sperm whale's great size allowed it to defend itself effectively against whalers.
