Urolophus Kaianus
The Kai stingaree (''Urolophus kaianus'') is a species of Myliobatiformes, stingray in the family (biology), family Urolophidae, known only from two juveniles collected from deep in the Kai Islands of eastern Indonesia. This species has a rhomboid pectoral fin with a very blunt, rounded snout, and a tail with lateral skin folds, a leaf-shaped caudal fin, and no dorsal fin. It is brown above with blackish coloring on the upper surface of each eyeball. The larger of the two specimens measures long. The International Union for Conservation of Nature (IUCN) does not yet have enough information to assess the Kai stingaree beyond Data Deficient. It presently faces little fishing, though this is liable to change in the future. Taxonomy From September 9 to 29, 1874, the research ship HMS Challenger (1858), HMS ''Challenger'' collected a number of hitherto-unknown fishes from Station 192 in the Kai Islands, including two specimens of the Kai stingaree.

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...
