The narwhal is a species of toothed whale native to the Arctic. It is the only member of the genus Monodon and one of two living representatives of the family Monodontidae. The narwhal has a similar build to the closely related beluga whale, with which it overlaps in range and can interbreed. It is a stocky cetacean with a relatively blunt snout, a large melon, and a shallow ridge in place of a dorsal fin. Males of this species have a large 1.5–3.0 m long tusk, which is a left protruded canine thought to serve as a weapon or as a tool for feeding, attracting mates or sensing water salinity. Specially adapted slow-twitch muscles, along with the jointed neck vertebrae and shallow dorsal ridge allow for easy movement through the Arctic environment, where the narwhal spends extended periods at great depths.
Pitcher plants are carnivorous plants known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of pitcher plant are considered to be "true" pitcher plants and are formed by specialized leaves. The plants attract and drown the prey with nectar.
The beluga whale is an Arctic and sub-Arctic cetacean. It is one of two members of the family Monodontidae, along with the narwhal, and the only member of the genus Delphinapterus. It is also known as the white whale, as it is the only cetacean to regularly occur with this colour; the sea canary, due to its high-pitched calls; and the melonhead, though that more commonly refers to the melon-headed whale, which is an oceanic dolphin.
Oxalidales is an order of flowering plants, included within the rosid subgroup of eudicots. This group comprises six families that contain approximately 2000 species in 58 genera. They are trees, shrubs or woody vines which are found in the wet tropics, particularly on mountains, and warm temperate zones, especially in the southern hemisphere. Compound leaves are common in Oxalidales and the majority of the species in this order have five or six sepals and petals. The following families are typically placed here:
Amborella is a monotypic genus of understory shrubs or small trees endemic to the main island, Grande Terre, of New Caledonia in the southwest Pacific Ocean. The genus is the only member of the family Amborellaceae and the order Amborellales and contains a single species, Amborella trichopoda. Amborella is of great interest to plant systematists because molecular phylogenetic analyses consistently place it as the sister group to all other flowering plants, meaning it was the earliest group to evolve separately from all other flowering plants.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. The family was created by William John Swainson in 1820.
The cetacean family Monodontidae comprises two living whale species, the narwhal and the beluga whale and at least four extinct species, known from the fossil record. Beluga and Narwhal are native to coastal regions and pack ice around the Arctic Ocean. Both species are relatively small whales, 3–5 m (9.8–16.4 ft) in length, with a forehead melon, and a short or absent snout. Premaxillary teeth are absent. They do not have a true dorsal fin, but do have a narrow ridge running along the back, which is much more pronounced in the narwhal. They are highly vocal animals, communicating with a wide range of sounds. Like other whales, they also use echolocation to navigate. Belugas can be found in the far north of the Atlantic and Pacific Oceans; the distribution of narwhals is restricted to the Arctic and Atlantic Oceans.
Cephalotus is a genus which contains one species, Cephalotus follicularis the Albany pitcher plant, a small carnivorous pitcher plant. The pit-fall traps of the modified leaves have inspired the common names for this plant, which also include Western Australian pitcher plant, Australian pitcher plant, or fly-catcher plant. It is an evergreen herb that is endemic to peaty swamps in the southwestern corner of Western Australia. As with the unrelated Nepenthes, it catches its victims with pitfall traps.
Muktuk, a traditional food of Inuit and other circumpolar peoples, consisting of whale skin and blubber. A part of Inuit cuisine, it is most often made from the bowhead whale, although the beluga and the narwhal are also used. It is usually consumed raw, but can also be eaten frozen, cooked, or pickled.
Badisis is a stilt-legged fly genus with only one known species, Badisis ambulans. This is a wingless, haltere-less fly with an ant-like appearance. It is only found in the Southwest Australian bioregion of Western Australia. Dependent on the rare Albany pitcher plant for its development, this fly is also a rare species.
Mesangiospermae is a clade of flowering plants (angiosperms) that contains about 99.95% of all angiosperm species. Mesangiosperms are therefore known as the core angiosperms, in contrast to the earlier-diverging species known as the basal angiosperms. Mesangiospermae includes about 350,000 species, while there are about 175 extant species of basal angiosperms.
Pitcher Plants of the Old World is a two-volume monograph by Stewart McPherson on the pitcher plants of the genera Nepenthes and Cephalotus. It was published in May 2009 by Redfern Natural History Productions and covers all species known at the time. The work was edited by Alastair Robinson and Andreas Fleischmann.
Ozichthys is a monotypic genus of cardinalfish, which was named and characterized in 2014. Its sole species, Ozichthys albimaculosus, is found in tropical Australia and southern New Guinea.
Trithuria inconspicua is a small aquatic herb of the family Hydatellaceae that is only found in New Zealand.
A narluga is a hybrid born from mating a female narwhal and a male beluga whale. Narwhals and beluga whales are both cetaceans found in the High Arctic and are the only two living members of the family Monodontidae.
In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, Amborella, and in this genus there is only one species, namely Amborella trichopoda.
The family Cephalotaceae has only one genus, Cephalotus, which contains only one species, Cephalotus follicularis, the Australian pitcher plant.
