THE WORD COELENTERATE MEANS HOLLOW BODY CAVITY. History- The term Phylum Coelenterata was introduced by a German zoologist, Karl Georg Friedrich (A) Rudolf Leuckart (1822-1898) who split Radiata into two phyla: Coelenterata and Echinodermata. Berthold Hatschek (1854-1941), split. Aurelia : 6 ppt. Ubur-ubur lainnya pada umumnya hidup pada 30 ppt. Rhizostoma : dapat hidup hingga komposisi : 30% air laut dan 70% air tawar. pH. 7,2-9,5.

Polypoid generation absent or represented by small polyps which give rise to medusae by strobilation Example: Aurelia, Rhizostoma. PowerPoint Presentation : Cnidaria: Classification Class Anthozoa Exclusively marine Solitary or colonial Medusoid stage absent Body hexamerous, octamerous or polymerous with biradial or radiobilateral symmetry. Animal eggs, which are non-motile, are much larger than the small, usually flagellated sperm. In animals, cells formed in meiosis function directly as gametes. The haploid cells do not divide by mitosis first, as they do in plants and fungi, but rather fuse directly with each other to form the zygote. 6

Obelia is sedentary, marine colonial form found attached on the surface of sea weeds, molluscan shells, rocks and wooden piles in shallow water up to 80 metres in depth. Obelia is cosmopolitan in distribution, forming a whitish or light-brown plant-like fur in the sea; hence, the common name sea-fur is assigned to it Rhizostoma: Rhizostoma (Fig. 35.9) is a large jelly-fish found in the shallow waters of Indo-Pacific region. It has a saucer-shaped umbrella with a scalloped margin having eight or sixteen tentaculocysts in different species, there are no marginal tentacles

Rhizostoma luteum has separate sexes, and the planulae are brooded by the female medusae inside the gonadal cavity. Planulae had a two-layered structure, white in colour, oval and elongate ( Fig 2A ), the sizes varied from 126 to 139 μm in length and 73 to 106 μm in width (n = 4; 132 ± 5 μm lengths, 84 ± 15 μm widths) Rhizostoma luteum is moderately venomous in a similar manner to R. pulmo (Kienberger, pers. observ.). However, because of its larger size (about 70 cm in diameter [6, 7]), the presence of Rhizostoma luteum near the coasts can have a negative impact on the image of touristic areas, as aforementioned, which are very sensitive to such issues The term alimentary canal or digestive tract in vertebrates refers to an internal tube, seldom straight and often tortuously coiled, running from an anterior mouth opening in head to a posterior anal or cloacal aperture at the base of tail. It is designed for ingestion, digestion and absorption of food stuffs and egestion of undigested wastes Lecture 3_coelentrata and Platy Helm Int Hes - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online.

Leuckart (1847) first coined the name Cnidaria. The term 'Cnidaria' is derived from two words; Gr. Knide=nettle and L. aria=like or connected with. Cnideraia are also known as Coelenterata. They have diverse colorful, radially symmetrical bodies which are known as the flower of the sea. The phylum Cnidaria contains more than 10,000 living species, among [ A.

wide range of temperatures (17-25°C) and salinities (1 ppt to 38 ppt). They are commonly found in coastal waters and brackish estuaries in depths of between 0 -50m, though they have been found as deep as 600 meters. Prior to its introduction in Europe, A. tonsa only occurred in the Indo-Pacific region and it is thought that this small crustacea Comparisons were made with early life history stages of its sibling species Rhizos-toma pulmo and Rhizostoma octopus. The life cycle of R. luteum follows the general pattern of metagenesis of scyphozoans. Scyphistoma culture was maintained in filtered seawater at 17-17.5 ˚C, salinity 37 and light photoperiod (12:12 h light:dark).. An epizootic of Caligus pageti on a fish farm in Egypt was associated with a high salinity of up to 45 ppt (Hewitt, 1971). C. orientalis , a parasite of cultured rainbow trout in Japan, is a euryhaline species that infects a wide range of other hosts, including Hucho perryi , Tribolodon hakonensis , Hypomesus transpacificus and M. cephalus.

PowerPoint プレゼンテーション Author: 上 真一 Created Date The nature of coloration in many marine animals remains poorly investigated. Here we studied the blue pigment of a scyfoid jellyfish Rhizostoma pulmo and determined it to be a soluble extracellular 30-kDa chromoprotein with a complex absorption spectrum peaking at 420, 588, and 624 nm. Furthermore, we cloned the corresponding cDNA and confirmed its identity by immunoblotting and mass. The jellyfish Rhizostoma pulmo, Macrì 1778 (Cnidaria, Rhizostomae) undergoes recurrent outbreaks in the Mediterranean coastal waters, with large biomass populations representing a nuisance or damage for marine and maritime activities.A preliminary overview of the antioxidant activity (AA) of R. pulmo proteinaceous compounds is provided here based on the extraction and characterization of both.

The past 30 years have seen several paradigm shifts in our understanding of how ocean ecosystems function. Now recent technological advances add to an overwhelming body of evidence for another paradigm shift in terms of the role of gelatinous plankton (jellyfish) in marine food webs. Traditionally viewed as trophic dead ends, stable isotope analysis of predator tissues, animal-borne cameras. Five stages of development were recognized, the number of larvae in the brood pouch ranged from 3 to 18. During the sampling period salinity ranged from 4 to 38 ppt, temperature from 13 to 39 0C, pH 8.0 to 8.5, and D.O. fluctuated from 4.9 to 9.0 mg/L. The salinity tolerance was also determined experimentally for I. annandalei Rhizostoma Pulmo species are commonly found in English waters, with diameters reaching 40 to 90 cm, and are generally used as processed food.

Bright colouration in animals has long attracted the attention of physicists, chemists and biologists. As such, studies on the functions of colours are interdisciplinary, focusing on the mechanisms of colour production and maintenance, the physical and chemical properties of the colour-producing elements, and visual systems and behaviour of potential receivers The growth increments were positively correlated with the statolith diameters, indicating a continuous growth rate of individual statoliths, as also was assumed for P. periphylla and Rhizostoma octopus (Holst et al., Reference Holst, Sötje, Tiemann and Jarms 2007; Sötje et al., Reference Sötje, Neues, Epple, Ludwig, Rack, Gordon, Boese and. Further, it has been shown that another scyphomedusa, Rhizostoma pulmo, can regenerate parts of the nervous system including the rhopalia after amputation (Hargitt, 1904); and cubopolyps have been shown to be able to regrow from a small lump of cells following metamorphosis (Strahler-Pohl and Jams, 2005).
