Cetacean Strandings In Tasmania
Cetacean strandings in Tasmania occur for a number of reasons, with Tasmania considered a "'hotspot" for the event. Between 1825 and 1986, 213 stranding events had been recorded, involving 22 species, and over 3000 individuals. Causes Cetacean strandings may occur for a number of reasons. These include natural causes, such as coastal topography and tidal patterns, searching for food, or a change in electromagnetic fields that could disorient them. Other causes include boat strikes, fishing. and pollution, that could result in injuries and stranding. Pilot whales in particular, living in strong social units, sometimes strand themselves to be with family. Stranding events 2020 long-finned pilot whale stranding In September 2020, more than 450 long-finned pilot whales stranded in Macquarie Harbour on the western coast of Tasmania, in Australia's worst-ever stranding event. Most were stranded on sandbanks and beaches around the mouth of the harbour. 50 were rescued, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whales
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Mysticetes include four extant (living) families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), and Eschrichtiidae (the grey whale). Odontocetes include the Monodontidae (belugas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Night Watch was disbanded in 1806 due to ineffectiveness and was replaced by British military patrols. A municipal police force was established at Port Dalrymple ( Launceston) on 19 November 1804, with Thomas Massey as Chief Constable. Formation With the introduction of the ''Police Regulation Act 1898'', one unified police force was established which came into being on 1 January 1899. George Richardson ...

Tasmania Parks And Wildlife Service
Tasmania Parks and Wildlife Service is the government body responsible for protected areas of Tasmania on public land, such as national parks, historic sites and regional reserves. Historically it has also had responsibility for managing wildlife, including game. History The National Parks and Wildlife Service was set up on 1 November 1971 after controversy surrounding the proposal to flood Lake Pedder and the unsuccessful attempts to prevent the project going ahead.

The service initially had a staff of 59. The '' National Parks and Wildlife Act 1970'' had made provisions for the conservation of fauna and flora and the establishment and management of national parks. Mount William, Maria Island and Narawntapu National Parks were set up and Macquarie Island designated as a nature reserve. The creation of an Ar ...

Cetacean Stranding
Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole. Cetacean stranding has occurred since before recorded history. Several explanations for why cetaceans strand themselves have been proposed, including changes in water temperatures, peculiarities of whales' echolocation in certain surroundings, and geomagnetic disturbances, but none have so far been universally accepted as a definitive reason for the behavior. However, a link between the mass beaching of beaked whales and use of mid-frequency active sonar has been found. Subsequently, whales that die due to stranding can decay and bloat to the point where they can easily explode, causing gas and their internal organs to fly out. Species Every year, up to 2,000 animals beach themselves. Although the majority of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the 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''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) 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, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). Mature males average in length, with the head representing up to one-third of the animal's length. Plunging to , it is the third deep ...
