Question: Besides dolphins and killer whales, what other animals can be seen in Hauraki Gulf Marine Park?

full_context: Document 1: Surfing in New Zealand: New Zealand is a popular surfing destination, with a long history of the sport and a varied coastline with locations suitable for all types of surfing. The West coast is notably consistent, with big swells and high winds, whereas the east coast is dominated by cyclone season swells; the North island is notably warmer than the South, but less consistent; mean temperatures range from 7°C to 20°C, depending on location and time of year. Winter is more consistent than Summer, with a southeasterly swell. The climate of New Zealand is varied, so different surf conditions are encountered across the islands.
Document 2: Killer whale: The killer whale or orca ("Orcinus orca") is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
Document 3: Kaikoura lights: The Kaikoura lights is a name given by the New Zealand media to a series of UFO sightings that occurred in December 1978, over the skies above the Kaikoura mountain ranges in the northeast of New Zealand's South Island. The first sightings were made on 21 December when the crew of a Safe Air Ltd cargo aircraft began observing a series of strange lights around their Armstrong Whitworth AW.660 Argosy aircraft, which tracked along with their aircraft for several minutes before disappearing and then reappearing elsewhere, the UFO was very large and had five white flashing lights that were visible on the craft. Some people say that they could see some little disks drop from the UFO and then disappear (they were never found). The pilots described some of the lights to be the size of a house and others small but flashing brilliantly. These objects appeared on the air traffic controller radar in Wellington and also on the aircraft's on-board radar.
Document 4: Namu, the Killer Whale: Namu, the Killer Whale (re-issued as Namu, My Best Friend) is a 1966 American film about a killer whale (orca) being studied by a local marine biologist and initially feared by local townspeople. The fictional story was filmed on location in the San Juan Islands and at Rich Cove near Port Orchard in the US state of Washington. The film 'starred' the orca Namu, one of the first orcas ever displayed in captivity.
Document 5: Melon-headed whale: The melon-headed whale or melon-headed dolphin (species "Peponocephala electra"; other names are many-toothed blackfish, "melon whale" and electra dolphin) is a cetacean of the oceanic dolphin family (Delphinidae). Theorized in the 1970s, it is closely related to the pygmy killer whale and pilot whale, and collectively these dolphin species are known by the common name blackfish. It is also related to the false killer whale. The melon-headed whale is widespread throughout the world's tropical waters, although not often seen by humans because it prefers deep water.
Document 6: Dwarf killer whale: The familiar killer whale ("Orcinus orca") is a cosmopolitan species, found in all oceans of the world. Despite being the most widespread mammal in the world, only one species is currently recognized. Oceanic Science journals have long hinted at the existence of a complex breed of miniature killer whales since the 1950's. The dwarf killer whale is a type of killer whale found in Antarctic waters believed by some scientists to be a distinct species from the larger killer whales found throughout the world's oceans. Since Soviet researchers proposed new species in the 1980's, the differences in killer whales have been studied more closely in order to gain more credible knowledge on possible subspecies of the killer whale. There are several ecotypes that have been established in regards to the whales physical appearances and body length by Pitman and colleagues. A recent study proposed by Pitman et al. (2007) used aerial photogrammetry to determine the size of numerous Type C killer whales, supporting early Soviet research which suggested that one or possibly two distinct species of killer whale exist in the Southern Ocean. Therefore, scientific evidence is starting to make the connection between ecotype C and the dwarf killer whale.
Document 7: Whale watching in New Zealand: Whale watching in New Zealand is predominantly centered around the areas of Kaikoura and the Hauraki Gulf. Known as the 'whale capital', Kaikoura is a world-famous whale watching site, in particular for sperm whales which is currently the most abundant of large whales in New Zealand waters. The Hauraki Gulf Marine Park (just outside Auckland city) is also a significant whale watching area with a resident population of Bryde's Whales commonly viewed alongside other cetaceans Common Dolphins, Bottlenose Dolphins and Orca. Whale watching is also offered in other locations, often as eco-tours and in conjunction with dolphin watching. Land-based whale watching from New Zealand's last whaling station, which closed in 1964, is undertaken for scientific purposes, mostly by ex-whalers. Some compilations of sighting footages are available on YouTube.
Document 8: Kaikoura Island: Kaikoura Island (formerly known as Selwyn Island) lies in an irregularly-shaped bay on the western side of Great Barrier Island in the Hauraki Gulf in New Zealand, 90 km north east of Auckland. Kaikoura Island is the seventh largest island in the Hauraki Gulf. It is 80 metres from Great Barrier Island at its closest point and forms the natural harbours of Port FitzRoy and Port Abercrombie. Its biota includes the endangered brown teal duck, the North Island kaka and many native trees and shrubs.
Document 9: Sea lion: Sea lions are sea mammals characterized by external ear flaps, long foreflippers, the ability to walk on all fours, and short, thick hair, big chest and belly. Together with the fur seals, they comprise the family Otariidae, eared seals, which contains six extant and one extinct species (the Japanese sea lion) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years. A male California sea lion weighs on average about 300 kg and is about 8 ft long, while the female sea lion weighs 100 kg and is 6 ft long. The largest sea lion is Steller's sea lion, which can weigh 1000 kg and grow to a length of 10 ft . Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 15 – ) at a single feeding.
Document 10: Eden Killer Whale Museum: The Eden Killer Whale Museum is a museum in Eden, New South Wales, Australia. It was originally built to house the skeleton of the orca "Old Tom" and tell its story. The local historical society is based at the museum, where it displays and houses between five and ten thousand items, focusing on the Australian whaling industry, general maritime and fishing artifacts, the timber industry, and local social history.
Document 11: Polar bear: The polar bear ("Ursus maritimus") is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear ("Ursus arctos middendorffi"). A boar (adult male) weighs around 350 – , while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.
Document 12: Hermanus: Hermanus (originally called "Hermanuspietersfontein", but shortened in 1902 as the name was too long for the postal service ), is a town on the southern coast of the Western Cape province of South Africa. It is famous for southern right whale watching during the southern winter and spring and is a popular retirement location. The whales can be seen from the cliffs in the town centre as early as June and usually depart in early-December. They were once hunted in the nearby town of Betty's Bay, but are now protected to ensure the survival of the species. The Old Harbour Museum contains several exhibitions that explain the whaling industry, and the De Wetshuis Photo Museum houses an exhibition of photos by T. D. Ravenscroft that depicts the history of Hermanus. The Whale Museum houses a skeleton of a whale and shows an audio-visual presentation of whales and dolphins twice daily.
Document 13: Killer whales of Eden, Australia: The killer whales of Eden, Australia were a group of killer whales ("Orcinus orca") known for their co-operation with human hunters of cetacean species. They were seen near the port of Eden in southeastern Australia between 1840 and 1930. A pod of killer whales, which included amongst its members a distinctive male called Old Tom, would assist whalers in hunting baleen whales. The killer whales would find target whales, shepherd them into Twofold Bay, and then alert the whalers to their presence and often help to kill the whales.
Document 14: Carousel feeding: Carousel feeding is a hunting technique used by the orca whale population in the waters off northern Norway. Orcas ("Orcinus orca") have adapted to life in a variety of environments and their hunting techniques are prey specific. Orcas that utilize the carousel feeding technique prey on wintering herring. This technique, like the majority of orca hunting techniques, involves cooperation. An individual or small group of orcas will herd the herring into a tight ball by releasing bursts of bubbles and/or flashing their white undersides. This tight ball differs in size, the diameter of the tight ball can range anywhere between two and seven meters They then push the herring close to the surface and stun them with tail slaps, allowing the orcas to catch and consume them. The carousel feeding duration can last from ten minutes to three hours. The orcas can catch and kill up to 15 herring with each successful slap. It is predicted that the orcas choose to use this hunting technique over others as a response to the behavior of the prey.
Document 15: Old Tom (killer whale): Old Tom ( 1895 – 17 September 1930) was a killer whale (orca) known to whalers in the port of Eden on the southeast coast of Australia. Old Tom measured 22 feet (6.7 m) and weighed 6 tons, with a 1.02 m skull and teeth about 5.31 inches (13.4 cm) long. Old Tom was thought to be the leader of a pod of killer whales which helped the whalers by herding baleen whales into Twofold Bay. The whalers then allowed the killer whales to eat the tongues and lips as their share of the kill, a practice known as the "Law of the Tongue".
