Cambaroides dauricus is a species of crayfish endemic to north-eastern China, the Korean Peninsula and neighbouring parts of Russia. [1]
Burying beetles or sexton beetles, genus Nicrophorus, are the best-known members of the family Silphidae. Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care of the brood. They are carnivores.
Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier acipenseriform fish who date back to the Triassic period some 245 to 208 million years ago. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct. Two closely related species, Polyodon spathula and Psephurus gladius are of the same order, Acipenseriformes, but are in the family Polyodontidae and are not considered to be "true" sturgeons. Both sturgeons and paddlefish have been referred to as "primitive fishes" because their morphological characteristics have remained relatively unchanged since the earliest fossil record. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America.
Richard's pipit is a medium-sized passerine bird which breeds in open grasslands in the East Palearctic. It is a long-distance migrant moving to open lowlands in the Indian subcontinent and Southeast Asia. It is a rare but regular vagrant to western Europe.
Dytiscus is a Holarctic genus of predaceous diving beetles that usually live in wetlands and ponds. There are 26 species in this genus distributed in Europe, Asia, North Africa and North and Central America. They are predators that can reduce mosquito larvae.
Spermophilus is a genus of ground squirrels in the squirrel family. As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs, marmots, and antelope squirrels. As a consequence, all the former Spermophilus species of North America have been moved to other genera, leaving the European and Asian species as true Spermophilus.
The beluga, also known as the beluga sturgeon or great sturgeon is a species of anadromous fish in the sturgeon family (Acipenseridae) of order Acipenseriformes. It is found primarily in the Caspian and Black Sea basins, and formerly in the Adriatic Sea. Going on maximum size, it is the third most massive living species of bony fish. Heavily fished for the female's valuable roe, known as beluga caviar, wild populations have been greatly reduced by overfishing and poaching.
The kaluga is a large predatory sturgeon found in the Amur River basin. Also known as the river beluga, they are claimed to be the largest freshwater fish in the world, with a maximum size of at least 1,000 kg (2,205 lb) and 5.6 m (18.6 ft). The kaluga is one of the biggest of the sturgeon family. Like the slightly larger beluga, it spends part of its life in salt water. Unlike the beluga, this fish has 5 major rows of dermal scutes, nail-like teeth in its jaws, and feeds on salmon and other fish in the Amur. They have gray-green to black backs with a yellowish green-white underbelly.
Cambaroides is a genus of freshwater crayfish from eastern Asia. Together with Astacus, they are the only crayfish native to Asia. Cambaroides contains about six species:
The Daurian ground squirrel is a species of rodent in the family Sciuridae. It is found in China, Mongolia, and Russia.
Huso is a genus of large sturgeons from Eurasia. It contains two species, which both are critically endangered:
Nicrophorus dauricus is a burying beetle described by Victor Motschulsky, a Russian entomologist, in 1860.
Nicrophorus orientalis may refer to:
Cossus cossus, the goat moth, is a moth of the family Cossidae. It is found in Northern Africa, Asia and Europe.
Peltodytes is a genus of water beetle which is native to the Nearctic, Europe, the Near East, and North Africa. Peltodytes can generally be differentiated from the similar Haliplus by the presence of a pair of spots on the posterior margin of the pronotum. The genus Peltodytes contains the following species:
Oreodytes is a genus of beetles in the family Dytiscidae, containing the following species:
Himacerus is a genus of damsel bugs belonging to the family Nabidae, subfamily Nabinae.
Brassicogethes aeneus, known generally as common pollen beetle, is a species of pollen beetle in the family Nitidulidae. Other common names include the rape pollen beetle and rape blossom beetle. It was previously known as Meligethes aeneus.
Dytiscus dauricus is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Palearctic.
Ceratophyus is a genus of earth-boring scarab beetles in the family Geotrupidae. There are about 13 described species in Ceratophyus.
Illidops is a genus of braconid wasps in the family Braconidae. There are more than 30 described species in Illidops, found throughout most of the world.
