Cerianthus Valdiviae
''Cerianthus'' is a genus of tube-dwelling anemones in the family Cerianthidae. Members of the genus are found worldwide. They are predators, scavengers and omnivores. Characteristics Members of this genus do not have a pedal disc with which to hold themselves in position. Instead they live semi-buried in soft substrate surrounded by a parchment-like tube which they secrete. This surrounds the whole anemone up to its crown of tentacles. Sand grains, debris and shell fragments usually stick to the outer side of the tube. When it is disturbed, the anemone retracts swiftly back into the tube. Some of the larger species can have a column of up to in length. The longitudinal muscles in the trunk are powerful but the transverse ones are weak. The outer ring of tentacles are long and tapering. The tube is flexible and the anemone can extend its tentacles a surprisingly long way. The inner ring of tentacles surrounds the central mouth and assists in pushing food inside. Species The fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerianthus Membranaceus
''Cerianthus membranaceus'', the cylinder anemone or coloured tube anemone, is a species of large, tube-dwelling anemone in the family Cerianthidae. It is native to the Mediterranean Sea and adjoining parts of the northeastern Atlantic Ocean. Description ''Cerianthus membranaceus'' is a large, tube-dwelling anemone. The oral disc can have a diameter of up to . There are two whorls of tentacles, amounting to about two hundred tentacles in all. Those in the outer whorl are long and slender and armed with cnidocytes (stinging cells) and are used for catching prey. Tentacles in the inner whorl are shorter and function to transfer captured food to the central mouth. The tentacles are sometimes banded and come in an array of colours; white, yellow, orange, green, brown, blue, black, purple and violet. The colour of the inner whorl often contrasts with that of the outer whorl. The column of this tube anemone secretes mucus in which is embedded a unique type of cnidocytes that mesh toget ...

Cerianthus Lloydii
''Cerianthus lloydii'' is a species of tube-dwelling sea anemone in the family Cerianthidae. It is sometimes called the lesser cylinder anemone and is found in shallow seas around the coasts of north west Europe. Taxonomy ''Cerianthus lloydii'' was first described by the English naturalist Philip Henry Gosse in 1859. The American zoologist Henry Weed Fowler in 1897 used the name ''Synarachnactis bournei'' to describe a juvenile anemone that he had discovered. It was later established that this was in fact the larval stage of ''C. lloydii''. Consequently, the name ''S. bournei'' was disallowed and is now considered a junior synonym of ''C. lloydii''. Description ''Cerianthus lloydii'' grows to about long. It does not have a pedal disc with which to attach itself to the substrate but instead lives in a flexible parchment-like tube up to long. This is buried in sand or mud with one end above the surface. Sand grains, debris and shell fragments usually stick to the outer side of ...
