The northern shrike is a large songbird species in the shrike family (Laniidae) native to North America and Siberia. Long considered a subspecies of the great grey shrike, it was classified as a distinct species in 2017. Six subspecies are recognised.
The Arctic warbler is a widespread leaf warbler in birch or mixed birch forest near water throughout its breeding range in Fennoscandia and the northern Palearctic. It has established a foothold in North America, breeding in Alaska. This warbler is strongly migratory; the entire population winters in southeast Asia. It therefore has one of the longest migrations of any Old World insectivorous bird.
Cory's shearwater is a large shearwater in the seabird family Procellariidae. It breeds colonially on the archipelago of the Azores in the eastern Atlantic. Outside the breeding season it ranges widely in the Atlantic. It was formerly considered to be conspecific with Scopoli's shearwater.
The Eskimo curlew, also known as northern curlew, is a species of curlew in the family Scolopacidae. It was one of the most numerous shorebirds in the tundra of western Arctic Canada and Alaska. Thousands of birds were then killed per year in the late 1800s. As there has not been a reliable sighting since 1987 or a confirmed sighting since 1963, the Eskimo curlew is considered Critically Endangered or possibly extinct. The bird is about 30 cm (12 in) long and fed mostly on insects and berries.
Isopachys is a genus of skinks, lizards in the family Scincidae. The genus is endemic to Asia.
The sei whale is a baleen whale. It is one of ten rorqual species, and the third-largest member after the blue and fin whales. It can grow to 19.5 m (64 ft) in length and weigh as much as 28 t. Two subspecies are recognized: B. b. borealis and B. b. schlegelii. The whale's ventral surface has sporadic markings ranging from light grey to white, and its body is usually dark steel grey in colour. It is among the fastest of all cetaceans, and can reach speeds of up to 50 km/h (31 mph) over short distances.
The northern right whale dolphin is a small, slender species of cetacean found in the cold and temperate waters of the North Pacific Ocean. Lacking a dorsal fin, and appearing superficially porpoise-like, it is one of the two species of right whale dolphin.
Lysimachia borealis, the starflower, is a North American woodland perennial that blooms between May and June.

The boreal digging frog is a species of microhylid, or "narrow-mouthed," frog found in Northeast Asia. Its range covers much of central and northeastern China, the Korean Peninsula, and Jeju Island. Adult boreal digging frogs are roughly 4.5 cm in length, round in shape with toad-like speckled skin. Tadpoles are up to 35 mm (1.4 in) in length.
Gyldenstolpe's worm skink, also known commonly as Gyldenstolpe's isopachys and Gyldenstolpe's snake skink, is a species of lizard in the family Scincidae. The species is endemic to Thailand.
Herbertus borealis is a species of liverwort in the family Herbertaceae known as northern prongwort. It was described in 1970 by Alan Crundwell. It is endemic to Scotland, where it is found only in the Beinn Eighe nature reserve, and lives in dwarf shrub heath alongside other large liverworts such as Anastrophyllum donnianum, Bazzania tricrenata and Pleurozia purpurea. A closely related species, described in 2012 as Herbertus norenus and known as "Viking prongwort", is known from Shetland and Norway and was formerly confused with H. borealis.
Isopachys anguinoides, commonly known as the Thai snake skink or Heyer's isopachys, is a species of skink in the family Scincidae.
Taonius borealis is a glass squid belonging to the genus Taonius. It is found in the North Pacific Ocean, ranging from Japan to southern California.
