The Role of Temperature in Survival of the Polyp Stage of the Tropical Rhizostome Jelly®Sh Cassiopea Xamachana
Journal of Experimental Marine Biology and Ecology, L 222 (1998) 79±91 The role of temperature in survival of the polyp stage of the tropical rhizostome jelly®sh Cassiopea xamachana William K. Fitt* , Kristin Costley Institute of Ecology, Bioscience 711, University of Georgia, Athens, GA 30602, USA Received 27 September 1996; received in revised form 21 April 1997; accepted 27 May 1997 Abstract The life cycle of the tropical jelly®sh Cassiopea xamachana involves alternation between a polyp ( 5 scyphistoma) and a medusa, the latter usually resting bell-down on a sand or mud substratum. The scyphistoma and newly strobilated medusa (5 ephyra) are found only during the summer and early fall in South Florida and not during the winter, while the medusae are found year around. New medusae originate as ephyrae, strobilated by the polyp, in late summer and fall. Laboratory experiments showed that nematocyst function, and the ability of larvae to settle and metamorphose change little during exposure to temperatures between 158C and up to 338C. However, tentacle length decreased and ability to transfer captured food to the mouth was disrupted at temperatures # 188C. Unlike temperate-zone species of scyphozoans, which usually over-winter in the polyp or podocyst form when medusae disappear, this tropical species has cold-sensitive scyphistomae and more temperature-tolerant medusae. 1998 Elsevier Science B.V. Keywords: Scyphozoa; Jelly®sh; Cassiopea; Temperature; Life history 1. Introduction The rhizostome medusae of Cassiopea xamachana are found throughout the Carib- bean Sea, with their northern limit of distribution on the southern tip of Florida. Unlike most scyphozoans these jelly®sh are seldom seen swimming, and instead lie pulsating bell-down on sandy or muddy substrata in mangroves or soft bottom bay habitats, giving rise to the common names ``mangrove jelly®sh'' or ``upside-down jelly®sh''. -

Population and Spatial Dynamics Mangrove Jellyfish Cassiopeia sp at Kenya’s Gazi Bay. American Journal of Life Sciences. Vol. 2, No. 6, 2014, pp. 395-399. doi: 10.11648/j.ajls.20140206.20 Abstract: Cassiopeia, the upside-down or mangrove jellyfish is a bottom-dwelling, shallow water marine sycophozoan of the phylum Cnidaria. It is commonly referred to as jellyfish because of its jelly like appearance. The medusa is the dominant phase in its life history. They have a radial symmetry and occur in shallow, tropical lagoons, mangrove swamps and sandy mud falls in tropical and temperate regions. In coastal Kenya, they are found only in one specific location in the Gazi Bay of the south coast. There are no documented studies on this species in Kenya. The objective of this study was to quantify the spatial and size-class distribution, and recruitment of Cassiopeia at the Gazi Bay. Ten 50mx50m quadrats were randomly placed in an estimated study area of 6.4ha to cover about 40 percent of the total study area. A total of 1043 individual upside-down jellyfish were sampled. In each quadrat, all jellyfish encountered were sampled individually. -

The massive occurrence of jellyfish in several areas of the world is reported annually, but most of the data come from the northern hemisphere and often refer to a restricted group of species that are not in the genus Cassiopea. This study records a massive, clonal and non-native population of Cassiopea and discusses the possible scenarios that resulted in the invasion of the Brazilian coast by these organisms. -

Chiang Mai Lampang Lamphun Mae Hong Son Contents Chiang Mai 8 Lampang 26 Lamphun 34 Mae Hong Son 40 View Point in Mae Hong Son Located some 00 km. from Bangkok, Chiang Mai is the principal city of northern Thailand and capital of the province of the same name. Popularly known as “The Rose of the North” and with an en- chanting location on the banks of the Ping River, the city and its surroundings are blessed with stunning natural beauty and a uniquely indigenous cultural identity. Founded in 12 by King Mengrai as the capital of the Lanna Kingdom, Chiang Mai has had a long and mostly independent history, which has to a large extent preserved a most distinctive culture. This is witnessed both in the daily lives of the people, who maintain their own dialect, customs and cuisine, and in a host of ancient temples, fascinating for their northern Thai architectural Styles and rich decorative details. Chiang Mai also continues its renowned tradition as a handicraft centre, producing items in silk, wood, silver, ceramics and more, which make the city the country’s top shopping destination for arts and crafts. Beyond the city, Chiang Mai province spreads over an area of 20,000 sq. km. offering some of the most picturesque scenery in the whole Kingdom. The fertile Ping River Valley, a patchwork of paddy fields, is surrounded by rolling hills and the province as a whole is one of forested mountains (including Thailand’s highest peak, Doi Inthanon), jungles and rivers. Here is the ideal terrain for adventure travel by trekking on elephant back, river rafting or four-wheel drive safaris in a natural wonderland. -

A Review of Toxins from Cnidaria
marine drugs Review A Review of Toxins from Cnidaria Isabella D’Ambra 1,* and Chiara Lauritano 2 1 Integrative Marine Ecology Department, Stazione Zoologica Anton Dohrn, Villa Comunale, 80121 Napoli, Italy 2 Marine Biotechnology Department, Stazione Zoologica Anton Dohrn, Villa Comunale, 80121 Napoli, Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-081-5833201 Received: 4 August 2020; Accepted: 30 September 2020; Published: 6 October 2020 Abstract: Cnidarians have been known since ancient times for the painful stings they induce to humans. The effects of the stings range from skin irritation to cardiotoxicity and can result in death of human beings. The noxious effects of cnidarian venoms have stimulated the definition of their composition and their activity. Despite this interest, only a limited number of compounds extracted from cnidarian venoms have been identified and defined in detail. Venoms extracted from Anthozoa are likely the most studied, while venoms from Cubozoa attract research interests due to their lethal effects on humans. The investigation of cnidarian venoms has benefited in very recent times by the application of omics approaches. In this review, we propose an updated synopsis of the toxins identified in the venoms of the main classes of Cnidaria (Hydrozoa, Scyphozoa, Cubozoa, Staurozoa and Anthozoa). We have attempted to consider most of the available information, including a summary of the most recent results from omics and biotechnological studies, with the aim to define the state of the art in the field and provide a background for future research. Keywords: venom; phospholipase; metalloproteinases; ion channels; transcriptomics; proteomics; biotechnological applications 1. -
Checkpoints in the Life-Cycle of Cassiopea Spp.: Control of Metagenesis and Metamorphosis in a Tropical Jellyfish
Int. J. Dc\'. BioI. ~O: 331-33R (1996) 331 Checkpoints in the life-cycle of Cassiopea spp.: control of metagenesis and metamorphosis in a tropical jellyfish# DIETRICH K. HOFMANN'*, WilLIAM K. FITT2 and JURGEN FLECK' 'Ruhr-University Bochum, Department of Zoology, Bochum, Germany and 2University of Georgia, Athens, Georgia, USA ABSTRACT Experimental data reveal that most, if not all, major events in the metagenetic life. cycle of Cassiopea spp. at these checkpoints depend on the interaction with specific biotic and physical cues. For medusa formation within a permissive temperature range by monodisk strobi. lation of the polyp, the presence of endosymbiotic dinoflagellates is indispensable. The priming effect of the algal symbionts is not primarily coupled with photosynthetic activity, but was found to be enhanced in the light. Budding of larva.like propagules by the polyp, however, is indepen- dent from such zooxanthellae. On the other hand the budding rate is influenced by various rear- ing conditions. Exogenous chemical cues control settlement and metamorphosis into scyphopolyps of both sexually produced planula larvae and asexual propagules. In laboratory experiments two classes of metamorphosis inducing compounds have been detected: a family of oligopeptides, featuring a proline-residue next to the carboxyterminal amino acid, and several phorbol esters. Using the peptide "C-DNS-GPGGPA, induction of metamorphosis has been shown to be receptor-mediated. Furthermore, activation of protein kinase C, a key enzyme within the inositolphospholipid-signalling pathway appears to be involved in initiating metamorphosis. In mangrove habitats of Cassiopea spp. planula larvae specifically settle and metamorphose on sub- merged, deteriorating mangrove leaves from which biologically active fractions have been isolat- ed.
