Calyptraea Chinensis
''Calyptraea chinensis'', common name the Chinese hat snail or Chinese hat shell, is a species of small sea snail, a marine gastropod mollusk in the family (biology), family Calyptraeidae, the slipper snails or slipper limpets, cup-and-saucer snails, and Chinese hat snails. Description The thin Gastropod shell, shell of this species has the shape of an almost symmetrical cone (like a Chinese hat or conical Asian hat), 7 mm high and 15 – 21 mm wide. The internal partition has a spirally curved edge which runs running from the Apex (mollusc), apex to the margin of the shell, and partly covers the Aperture (mollusc), aperture. The presence of this internal shelf distinguishes this species easily from the true limpets. The aperture is round and adapted to the substrate. The shell is creamy white, and glossy on the inside. ''Calyptraea chinensis'' is a filter feeder, binding fine food particles with mucus. Like all slipper limpets, this species is a Dichogamy, protandrou ...

Animal
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] |
