The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song that typically lasts from 4 to 33 minutes.

Found in oceans and seas around the world, humpback whales typically migrate between feeding areas towards the poles and breeding areas near the equator. Their diet consists mostly of krill and small fish, and they usually use bubbles to catch prey. They are polygynandrous breeders, with both sexes having multiple partners. Males will follow females and fight off rivals. Mothers give birth to calves in shallower water. Orcas are the main natural predators of humpback whales. The bodies of humpbacks host barnacles and whale lice.

The longfin sculpin (Jordania zonope) is a species of marine ray-finned fish belonging to the family Jordaniidae, a small family of sculpins. This species is found in the northeastern Pacific Ocean. This species is the only known member of its genus, Jordania.

Riftia pachyptila is a marine invertebrate in the phylum of segmented worms, Annelida, which include the other "polychaete" tube worms commonly found in shallow water marine environments and coral reefs. R. pachyptila lives in the deep sea, growing on geologically active regions of the Pacific Ocean's seafloor, such as near hydrothermal vents. These vents provide a natural ambient temperature ranging from 2 to 30 degrees Celsius (36 to 86 °F), and emit large amounts of chemicals such as hydrogen sulfide, which this species can tolerate at extremely high levels. These worms can reach a length of 3 m (9 ft 10 in), and their tubular bodies have a diameter of 4 cm (1.6 in).

Historically, the genus Riftia (which only contains this species) was placed within the phyla Pogonophora and Vestimentifera. It has been informally known as the giant tube worm or the giant beardworm; however, the former name is also used for the largest living species of shipworm, Kuphus polythalamius, which is a type of bivalve (a group of molluscs which includes clams, mussels, and scallops).

Abalone (/ˈæbəloʊni/ or /ˌæbəˈloʊni/; via Spanish abulón, from Rumsen aulón) are sea snails in the genus Haliotis, the only genus in the family Haliotidae. Abalone shells are distinctive for their flattened, ear-like shape, nacreous interior, and row of holes used for respiration. The flesh of abalone is widely considered to be a delicacy, and is consumed raw or cooked by a variety of cuisines. Abalone are globally distributed, with approximately 70 known species alive today. Though some species are small, the largest abalone can attain a length of 300 millimetres (12 in).

The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative of its family Ornithorhynchidae and genus Ornithorhynchus, though a number of related species appear in the fossil record. Together with the four species of echidna, it is one of the five extant species of monotremes, mammals that lay eggs instead of giving birth to live young. Like other monotremes, the platypus has a sense of electrolocation, which it uses to detect prey in water while its eyes, ears and nostrils are closed. It is one of the few species of venomous mammals, as the male platypus has a spur on each hind foot that delivers an extremely painful venom.

The unusual appearance of this egg-laying, duck-billed, beaver-tailed mammal at first baffled European naturalists. In 1799, the first scientists to examine a preserved platypus body judged it a fake made of several animals sewn together. The unique features of the platypus make it important in the study of evolutionary biology, and a recognisable and iconic symbol of Australia. It is culturally significant to several Aboriginal peoples, who also used to hunt it for food, and has appeared on stamps and currency.

Nypa fruticans, commonly known as the nipa palm (or simply nipa, from Malay: nipah) or mangrove palm, is a species of palm native to the coastlines and estuarine habitats of the Indian and Pacific Oceans. It is the only palm considered adapted to the mangrove biome. The genus Nypa and the subfamily Nypoideae are monotypic taxa because this species is their only member.

Cupressaceae or the cypress family is a family of conifers. The family includes 27–30 genera (17 monotypic), which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species. The family reached its peak of diversity during the Mesozoic era.

Cryptomeria (literally "hidden parts") is a monotypic genus of conifer in the cypress family Cupressaceae. It includes only one species, Cryptomeria japonica (syn. Cupressus japonica L.f.). It is considered to be endemic to Japan, where it is known as Sugi (杉). The tree is also called Japanese cedar or Japanese redwood in English. It has been extensively introduced, and cultivated for wood production on the Azores and elsewhere.

The impala or rooibok (Aepyceros melampus, lit. 'black-footed high-horn' in Ancient Greek) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros, and tribe Aepycerotini, it was first described to Europeans by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the grassland-dwelling common impala (sometimes referred to as the Kenyan impala), and the larger and darker black-faced impala, which lives in slightly more arid, scrubland environments. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–65 kg (88–143 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.

Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala is known for two characteristic leaps that constitute an anti-predator strategy. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). An annual, three-week-long rut takes place toward the end of the wet season, typically in May. Rutting males fight over dominance, and the victorious male courts females in oestrus. Gestation lasts six to seven months, following which a single calf is born and immediately concealed in cover. Calves are suckled for four to six months; young males—forced out of the all-female groups—join bachelor herds, while females may stay back.

The blood pheasant (Ithaginis cruentus) or blood partridge is a galliforme bird in the pheasant family Phasianidae and the only species in the genus Ithaginis. It is a relatively small, short-tailed pheasant that is widespread in the lower Himalayas ranging across North and East India, Nepal, Bhutan, South China and northern Myanmar. It has been classified as Least Concern on the IUCN Red List since 2009, and the global blood pheasant population is thought to be stable.

The blood pheasant is the state bird of Sikkim, India.
