 This module may have lesser invertebrate cycloin force code discussed correctly. Cycleoforce, this is the phyla. This word is a combination of two Greek words, Cycleon meaning small wheel and Phora mean carry. This is the mostly recently described animal phyla that is included in this minor invertebrates. In its members there is only one species known as Simbio Pandora. Usually these animals are acylomide, marine and bilateral symmetrical. They live in association with the mouth parts of the lobsters. The body of the feeding stage of Simbion that consists of a funnel which is known as buccal funnel, a trunk, a stalk that ends in the adhesive disc. A disc to have this attaches to the sitae on the mouth parts of the lobster host. The buccal funnel contains the mouth and is surrounded by a ring of compound cilia and these cilia are usually used for filter feeding. Outside the body there is a cuticle. The mouth this leads into a U shaped gut tract. Protonephridia are present and these protonephridia are used in excretion. Asexual reproduction will take place and asexual feeding stage of Simbion is usually 0.3 millimeter tall. It can reproduce asexually by producing a larval stage which is known as Pandora. This is released from the body and ultimately it streams and settles on the same host. Because of this asexual reproduction large number of Simbion can be seen on one host. After settling and attaching new individual usually develops a buccal funnel and once this buccal funnel is developed they start their own feeding and then do not depend upon the host for feeding. Sexual reproduction is apparently correlated to the mold cycle of the lobster. However some hormonal changes can take place and hormones they are produced from the lobster signal Simbion and when the molting phenomena of molting takes place. Male and female stages are produced within the bodies of feeding and that contains the mature female. As the female escapes from its maternal feeding individual fertilization occult then female settles on to the lobster's mouth parts. The female contain a single large fertilized egg. If then the female dies leaving a cuticular shell containing a cordoid larva. This larva cordoid larva is the dispersal stage. It is free swimming and it may settle on the mouth appendages of a new lobster host. Here is the diagram showing the different features of cyclopores that we discussed. Here you can see its epidermis, its compound cilia of mouth ring, neck, ganglion that is brain, gut lining cilia, digestive tract, developing mouth ring of internal bud, adhesive disc. Through this this will attach to the lobster, lobster setae and these are epithelial cells and this is the anus. So this is the minor invertebrate cyclopores having only one species symbion Pandora.
