Ctenophora singular ctenophore, or from the Greek kteis comb and pher carry commonly known as comb jellies is a phylum of invertebrate animals that live in marine waters worldwide. They are notable for the groups of cilia they use for swimming commonly referred to as combs, and they are the largest animals that swim by means of cilia. Depending on the species, adult ctenophores range from a few millimeters to 1. Only 1. 001. 50 species have been validated, and possibly another 2. The textbook examples are cydippids with egg shaped bodies and a pair of retractable tentacles fringed with tentilla little tentacles that are covered with colloblasts, sticky cells that capture prey.

Almost all ctenophores are predators, taking prey ranging from microscopic larvae and rotifers to the adults of small crustaceans the exceptions are juveniles of two species, which live as parasites on the salps on which adults of their species feed. Most species are hermaphrodites, and juveniles of at least some species are capable of reproduction before reaching the adult size and shape. This combination of hermaphroditism and early reproduction enables small populations to grow at an explosive rate. Lenovo System Update Windows 7 T410. Early writers combined ctenophores with cnidarians into a single phylum called Coelenterata on account of morphological similarities between the two groups. Like cnidarians, the bodies of ctenophores consist of a mass of jelly, with one layer of cells on the outside and another lining the internal cavity. In ctenophores, however, these layers are two cells deep, while those in cnidarians are only a single cell deep. Ctenophores also resemble cnidarians in relying on water flow through the body cavity for both digestion and respiration, as well as in having a decentralized nerve net rather than a brain. However, genomic studies have suggested that the neurons of Ctenophora, which differ in many ways from other animal neurons, evolved independently from those of the other animals,6 and increasing awareness of the differences between the groups has persuaded more recent authors to classify the two as separate phyla.

Ctenophores form an animal phylum that is more complex than sponges, about as complex as cnidarians jellyfish, sea anemones, etc., and less complex than bilaterians. The thriving capital of Greece sprawls out from the foot of its magnificent Acropolis. Well tour the mustsees of ancient Athens the Parthenon, Agora, and amazing. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb rows than modern forms, have been found in Lagersttten as far back as the early Cambrian, about 5. Nevertheless, a recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid like, and that all the modern groups appeared relatively recently, probably after the CretaceousPaleogene extinction event. Distinguishing featureseditCtenophores form an animalphylum that is more complex than sponges, about as complex as cnidarians jellyfish, sea anemones, etc., and less complex than bilaterians which include almost all other animals. Unlike sponges, both ctenophores and cnidarians have cells bound by inter cell connections and carpet like basement membranes muscles nervous systems and some have sensory organs. Ctenophores are distinguished from all other animals by having colloblasts, which are sticky and adhere to prey, although a few ctenophore species lack them. Like sponges and cnidarians, ctenophores have two main layers of cells that sandwich a middle layer of jelly like material, which is called the mesoglea in cnidarians and ctenophores more complex animals have three main cell layers and no intermediate jelly like layer.

Opposite Side Of The Sea Zip' title='Opposite Side Of The Sea Zip' />CarmelbytheSea, k r m l often simply called Carmel, is a city in Monterey County, California, United States, founded in 1902 and incorporated on. Hence ctenophores and cnidarians have traditionally been labelled diploblastic, along with sponges. Both ctenophores and cnidarians have a type of muscle that, in more complex animals, arises from the middle cell layer,1. Ranging from about 1 millimeter 0. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb like bands of cilia, called ctenes, stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name ctenophora means comb bearing, from the Greek stem form meaning comb and the Greek suffix meaning carrying. DescriptioneditFor a phylum with relatively few species, ctenophores have a wide range of body plans. Coastal species need to be tough enough to withstand waves and swirling sediment particles, while some oceanic species are so fragile that it is very difficult to capture them intact for study. In addition oceanic species do not preserve well,8 and are known mainly from photographs and from observers notes. Hence most attention has until recently concentrated on three coastal genera Pleurobrachia, Beroe and Mnemiopsis. At least two textbooks base their descriptions of ctenophores on the cydippid. Pleurobrachia. 71. Since the body of many species is almostradially symmetrical, the main axis is oral to aboral from the mouth to the opposite end. However, since only two of the canals near the statocyst terminate in anal pores, ctenophores have no mirror symmetry, although many have rotational symmetry, in other words if the animal rotates in a half circle it looks the same as when it started. Common featureseditBody layersedit. Section through a Pleurobrachia like cydippid ctenophore. Left side shows canal from stomach to tentacle, right shows canal from stomach to comb row. Like those of cnidarians, jellyfish, sea anemones, etc., ctenophores bodies consist of a relatively thick, jelly like mesoglea sandwiched between two epithelia, layers of cells bound by inter cell connections and by a fibrous basement membrane that they secrete. The epithelia of ctenophores have two layers of cells rather than one, and some of the cells in the upper layer have several cilia per cell. The outer layer of the epidermis outer skin consists of sensory cells cells that secrete mucus, which protects the body and interstitial cells, which can transform into other types of cell. In specialized parts of the body the outer layer also contains colloblasts, found along the surface of tentacles and used in capturing prey, or cells bearing multiple large cilia, for locomotion. The inner layer of the epidermis contains a nerve net, and myoepithelial cells that act as muscles. The internal cavity forms a mouth that can usually be closed by muscles a pharynx throat a wider area in the center that acts as a stomach and a system of internal canals. These branch through the mesoglea to the most active parts of the animal the mouth and pharynx the roots of the tentacles, if present all along the underside of each comb row and four branches round the sensory complex at the far end from the mouth two of these four branches terminate in anal pores. The inner surface of the cavity is lined with an epithelium, the gastrodermis. The mouth and pharynx have both cilia and well developed muscles. Events at Sea 2. 01. From a passenger 2. May off Brest An incident occured that was not explained. During the afternoon the ship slowed from 1. Helicopter arrived, then departed. Two fighter jets flew overhead. About an hour and a half later the helicopter returned. No enlightening announcement was made. Would be interested to know what that was all about Some security alert perhaps Do any readers have any information Response from a reader I wasnt on board, but from the description, it sounds like a medical evacuation. A helicopter arrives the first time to drop by a medical technician and a gurney, then comes back a second time to pick up the patient, technician, and gurney. Its not all done in one shot. Its pretty standard for other military or coast guard airplaneshelicopters to fly around the vessel during this time for security purposes. To keep the privacy of the family, depending on the incident, the captain may or may not announce the medical evacuation as they generally dont affect a ship itinerary as they take roughly 1 1.
