Morula Mutica
''Azumamorula mutica'', common name the smooth ricinula, is a species of sea snail, a marine gastropod mollusk in the family (biology), family Muricidae, the murex snails or rock snails. It is the only species in genus ''Azumamorula''. Description The shell size varies between 15 mm and 20 mm Distribution This species is distributed in the Indian Ocean along Madagascar, the Mascarene basin, Réunion, and along Eastern Australia. Taxonomy This species was originally named ''Ricinula mutica'' by Lamarck in 1816, grouping it with species that are now mostly in ''Drupa'' and ''Morula''. In 1823, Dall defined two new genera, ''Drupina'' and ''Morulina'', to hold species of ''Drupa'' and ''Morula'' having simple non-plaited columnellae. He chose ''R. mutica'' as the type species for ''Morulina''. Thiele in 1931 and Wenz in 1941 had placed ''Morulina'' into ''Drupa''. In 1968, Emerson found that the teeth on the radula of ''D. mutica'' had an unusual shape. As a resul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, 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 Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
