Porpoises are small dolphin-like cetaceans classified under the family Phocoenidae. Although similar in appearance to dolphins, they are more closely related to narwhals and belugas than to the true dolphins. There are eight extant species of porpoise, all among the smallest of the toothed whales. Porpoises are distinguished from dolphins by their flattened, spade-shaped teeth distinct from the conical teeth of dolphins, and lack of a pronounced beak, although some dolphins also lack a pronounced beak. Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates.
Cook Strait is a strait that separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is 22 kilometres (14 mi) wide at its narrowest point, and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington.
Protected areas of South Australia, consisting of protected areas located within South Australia and its immediate onshore waters and which are managed by South Australian Government agencies. As of 2018, South Australia contained 359 separate protected areas declared under the National Parks and Wildlife Act 1972, the Crown Land Management Act 2009 and the Wilderness Protection Act 1992. Together, they cover a total land area of 211,387.48 km2 (81,617.16 sq mi) or 21.5% of the state's area.
Whale watching is the practice of observing whales and dolphins (cetaceans) in their natural habitat. Whale watching is mostly a recreational activity, but it can also serve scientific and/or educational purposes. A study prepared for International Fund for Animal Welfare in 2009 estimated that 13 million people went whale watching globally in 2008. Whale watching generates $2.1 billion per annum in tourism revenue worldwide, employing around 13,000 workers. The size and rapid growth of the industry has led to complex and continuing debates with the whaling industry about the best use of whales as a natural resource.
The southern right whale is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena. Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. In 2009 the global population was estimated to be approximately 13,600.
The Irrawaddy dolphin is a euryhaline species of oceanic dolphin found in scattered subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. It closely resembles the Australian snubfin dolphin, which was not described as a separate species until 2005. It has a slate blue to a slate gray color. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha, India and Songkhla Lake in southern Thailand.
Heaviside's dolphin is one of four dolphins in the genus Cephalorhynchus. The small cetacean is endemic to the Benguela ecosystem along the southwest coast of Africa.
Hector's dolphin is one of four dolphin species belonging to the genus Cephalorhynchus. Hector's dolphin is the only cetacean endemic to New Zealand, and comprises two subspecies: C. h. hectori, the more numerous subspecies, also referred to as South Island Hector's dolphin; and the critically endangered Māui dolphin, found off the West Coast of the North Island.
Humpback dolphins are members of the genus Sousa. These dolphins are characterized by the conspicuous humps and elongated dorsal fins found on the backs of adults of the species. Humpback dolphins inhabit shallow nearshore waters along coastlines across Australia, Africa, and Asia. Their preference for these habitats exposes them to various human activities such as fisheries entanglement, boat traffic, pollution, and habitat loss. Despite these risks, their nearshore presence facilitates easy observation from land.
The southern right whale dolphin is a small and slender species of cetacean, found in cool waters of the Southern Hemisphere. It is one of two species of right whale dolphin. This genus is characterized by the lack of a dorsal fin. The other species, the northern right whale dolphin, is found in deep oceans of the Northern Hemisphere and has a different pigmentation pattern than the southern right whale dolphin.
Te Waewae Bay is the westernmost of three large bays lying on the Foveaux Strait coast of Southland, New Zealand, the others being Oreti Beach and Toetoes Bay. Twenty-seven kilometres in length, the western end of the bay is mountainous, with the southern terminus of the Southern Alps and Fiordland National Park.
Pelorus Sound is the largest of the sounds which make up the Marlborough Sounds at the north of the South Island, New Zealand.
The Sundarbans National Park is a national park in West Bengal, India, and core part of tiger reserve and biosphere reserve. It is part of the Sundarbans on the Ganges Delta and adjacent to the Sundarban Reserve Forest in Bangladesh. It is located to south-west of Bangladesh. The delta is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger. It is also home to a variety of bird, reptile and invertebrate species, including the salt-water crocodile. The present Sundarban National Park was declared as the core area of Sundarban Tiger Reserve in 1973 and a wildlife sanctuary in 1977. On 4 May 1984 it was declared a national park. It is a UNESCO World Heritage Site inscribed in 1987, and it has been designated as a Ramsar site since 2019. It is considered as a World Network of Biosphere Reserve from 1989.
Cetacean bycatch is the accidental capture of non-target cetacean species such as dolphins, porpoises, and whales by fisheries. Bycatch can be caused by entanglement in fishing nets and lines, or direct capture by hooks or in trawl nets.
Curio Bay is a coastal embayment in the Southland District of New Zealand, best known as the site of a petrified forest some 180 million years old. It also hosts a yellow-eyed penguin colony, arguably the rarest of penguin species, with approximately 1600 breeding pairs in the extant population. The bay, along with neighbouring Porpoise Bay, is home to the endemic Hector's dolphin. Southern right whales are occasionally observed offshore, as on numerous parts of the country's coast. Located near the southernmost point of the South Island, Curio Bay is one of the major attractions in the Catlins, attracting around 100,000 visitors per year. The town of Waikawa has an information centre for tourists.
Nugget Point is one of the most iconic landforms on the Otago coast in New Zealand. Located at the northern end of the Catlins coast, along the road from Kaka Point, this steep headland has a lighthouse at its tip, surrounded by rocky islets. The point is home to many seabirds, including penguins, gannets and royal spoonbills, and a large breeding colony of fur seals. Roaring Bay, on the south coast of the tip of Nugget Point, is home to a small colony of yellow-eyed penguins.
Waikawa is a small settlement at the mouth of the Waikawa River in Southland, New Zealand, at the southwestern edge of The Catlins.
Hawea Marine Reserve is a marine reserve covering an area of 411 hectares in Hāwea / Bligh Sound, in Fiordland on New Zealand's South Island. It was established in 2005 and is administered by the Department of Conservation.
The marine conservation zones in Yorkshire, were created in 2016 and 2019 after an extensive consultation, which drew criticism of the UK Government's plans which designated only 31 zones out of the projected 127 zones in 2013. An £8 million study recommended the 127 sites, of which, eight lay in and around the coast of Yorkshire.
Long Island-Kokomohua Marine Reserve is a marine reserve, in the Marlborough Region of New Zealand's South Island. It covers an area of 619 hectares at the entrance to the Queen Charlotte Sound in the Marlborough Sounds. It was the first marine reserve established on the South Island.
