Sclerasterias Mazophora
''Sclerasterias'' is a genus of starfish in the family Asteriidae. Adult individuals have five arms but small, immature individuals have six. This led to the giving of a separate generic name to the juveniles, ''Hydrasterias'', before it was realised that only one genus was involved. These young individuals often undergo fissiparity. The disc splits into two parts, each bearing three arms, and new arms develop on each part to complete the complement of arms. This sometimes happens repeatedly and may be an adaptation to life in cold, deep seas where most of the species are found. Species The following species are accepted by the World Register of Marine Species: * '' Sclerasterias alexandri'' (Ludwig, 1905) * '' Sclerasterias contorta'' (Perrier, 1881) * ''Sclerasterias dubia'' (H. L. Clark, 1909) * '' Sclerasterias eructans'' (McKnight, 2006) * '' Sclerasterias euplecta'' (Fisher, 1906) * '' Sclerasterias eustyla'' (Sladen, 1889) * '' Sclerasterias guernei'' Perrier, 1891 * ...

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 ...
