“…Studies on the behavior and life cycle of cnidarian species in the laboratory and in situ are still rare for many groups of cnidarians, especially Ceriantharia (Tiffon 1987), although such studies are essential to identifying the species and populations (e.g., Jarms et al 2002).…”

“…Traditionally, linking larvae to adults, and vice versa, depends on direct studies of the life cycles; however, rearing larvae in the laboratory may be complex and timeconsuming, particularly for species with long-lived larval stages (Jarms et al 2002). Also, morphological data may have limited distinguishing power for specific identification of larvae collected in the field, due to phenotypic plasticity in larval morphology as well as variation in life-cycle patterns, for species with complex life cycles (e.g., Boero et al 1992;Minelli and Fusco 2010).…”

“…The cubopolyps and young medusae were cultured as described by Jarms et al (2002) and by Straehler-Pohl & Jarms (2011). Metamorphosis could not be induced artificially, but it occurred during the spring and summer period (May to September) when room temperature rose above 24°C and direct sunlight penetrated the room at least 4-5 hours a day.…”

Abstract:The name Carybdea morandinii Straehler-Pohl & Jarms, 2011 was applied to unknown cubopolyps found on dead coral rock at the Hagenbeck Zoo, Hamburg, Germany, during 1999, and a description was given of its early life history. Although included in Carybdeidae Lesson, 1843, its familial affinities remained uncertain. In 2006, a population of unidentified cubopolyps was discovered on the walls of a saltwater tank at the Umikirara Aquarium, Nagasaki, Japan. In addition, an immature cubomedusa and polyps were collected at Ginowan and Ishigaki, Okinawa, Japan, in 2002 and 2012. Genetic analysis established that these polyps and the medusa belonged to the same species as the polyps found in Nagasaki. Comparisons of the anatomy and asexual propagation methods of Japanese polyps, and their newly detached medusae, with early life stages of cubozoans cultured in Germany, revealed that the Japanese populations were likely conspecific with Carybdea morandinii. Subsequent genetic analysis confirmed this identification. Morphology of Japanese medusae revealed that they were referable to the family Alatinidae Gershwin, 2005, and within that family to the genus Alatina Gershwin, 2005, rather than to the family Carybdeidae.

“…These zooxanthellae form symbiotic associations with invertebrates such as foraminiferans, sponges, cnidarians, and mollusks, which use them to obtain photosynthetic energy in the form of carbohydrates. This relationship is vital to many species of cnidarians, considering that the loss of zooxanthellae from host tissues causes the phenomenon known as bleaching, which can cause the host's death [16,19,20,25,49]. A plethora of studies on this symbiosis has been conducted with reefbuilding scleractinian corals [5,18].…”

Response of the zooxanthellae of Palythoa caribaeorum (Cnidaria: Zoanthidea) to different environmental conditions in coastal and oceanic ecosystems of the Tropical Atlantic

The present study tested the hypothesis that endosymbionts of the zoanthid Palythoa caribaeorum show specific responses in cell density, size, and mitotic index (as proxy for cell population growth) under different environmental conditions (water depth, position within the reef and within the colony). Colony fragments were sampled at the nearshore coastal reefs of Porto de Galinhas and at the oceanic St. Peter and St. Paul's archipelago (SPSP), Brazil. At the coastal reefs, zooxanthellae showed higher density on the reef flat (mean: 2.99 × 10 6 cm −2) than at the back reef (mean: 2.07 × 10 6 cm −2). Zooxanthellae were larger at the center of the colonies (mean: 10.61 µm) than at the edges (mean: 10.11 µm), where younger polyps were found. At SPSP, zooxanthellae showed smaller cell diameters at 3 m depth, than at 5-15 m. Cell size increased with depth, thus enhancing the photosynthetic efficiency of colonies in deeper environments. Strategies and adaptations of these endosymbionts to environmental stressors are discussed. Symbiont distribution patterns shown in this study have fundamental implications for the monitoring of the health of tropical reef ecosystems.
