Nausithoe aurea n. sp. (Scyphozoa: Coronatae: Nausithoidae), a species with two pathways of reproduction after strobilation: sexual and asexual

Bijdragen tot de Dierkunde (1997)

Fábio Lang da Silveira André C. Morandini

Nausithoe aurea, a new species of scyphozoan Coronatae, is described from Sao Paulo State, Brazil. The solitary scyphistomae, with some zooxanthellae, strobilated producing planuloids and medusae; this represents an intermediate life cycle between that of metagenetic Nausithoidae and the submarine cave-dwelling, reduced medusa stage of Nausithoe planulophora (Werner, 1971). The periderm tube of the scyphistomae has 16 internal cusps in all whorls. The medusae present yellow pigment spots in most of their lappets. The early embryonic development is briefly described. Planuloid formation is hypothesized as explanation for polyp-stage philopatry.

All non-indigenous species were introduced recently? The case study of Cassiopea (Cnidaria: Scyphozoa) in Brazilian waters

Journal of the Marine Biological Association of the United Kingdom (2016)

André C. Morandini Sérgio N. Stampar Maximiliano M. Maronna Fábio Lang da Silveira

Upside-down jellyfish (genus Cassiopea ) can be found in tropical coastal waters worldwide. Until now reports of the genus from Brazilian waters have been scant. We report here medusae and scyphistomae collected from Cabo Frio, Rio de Janeiro state. Although we could not unambiguously identify the material using morphological criteria, genetic sequence data (COI) indicate that the Brazilian jellyfishes are genetically similar to those from Bermuda, Hawaii and Florida, which are related to specimens from the Red Sea ( Cassiopea andromeda ). We hypothesize that the presence of C. andromeda in Brazil is due to an invasion event, as the scyphistomae were found growing over the known invasive ascidian Styela plicata . Estimation of divergence time between Brazil (Cabo Frio) and Florida/Bermuda populations is that it occurred at the beginning of ship movement to South America.

Food resources influencing the asexual reproductive cycle of coronate Scyphozoa

Cahiers de biologie marine (2008)

Sérgio N. Stampar Fábio Lang da Silveira André C. Morandini

The study of the strobilation process, a feature unique in the class Scyphozoa, is an issue that helps understanding the patterns of asexual reproduction in sessile invertebrates. Many inducers of asexual reproduction are known for scyphozoans. However, the influence of food resources on the strobilation of Coronate Scyphozoa has never been tested. We observed strobilation of a large number of polyps of Nausithoe aurea, from a wide sampling area along the South Atlantic coast of Brazil, through the administration of controlled number of hatched nauplii of Artemia franciscana under a previous tested starvation and feeding protocol. The number of strobilations between and within groups varied and the fate and shape of strobilation deviated from the biology reported in the original description. Artificial seawater was used to reduce the influence of dissolved organic matter as likely important alternative nourishment.

Experiments in nature and laboratory observations with Nausithoe aurea (Scyphozoa: Coronatae) support the concept of perennation by tissue saving and confirm dormancy

Biota Neopropica/Biota Neotropica (2002)

Fábio Lang da Silveira Gerhard Jarms André C. Morandini

Stephanocyphistomae of Nausithoe aurea from São Paulo State, Brazil (in subtropical western South Atlantic wa-ters), were relocated with their substrata in nature to study their survivorship under control and and experimental series - i.e. the polyps in the original orientation and inverted, and in each series exposed and buried polyps. We found that N. aurea survives over 13 months in nature, between 1/3 - 1/4 of 268 stephanoscyphistomae as normal feeding polyps, by segmentation produces planuloids and rejuvenates the polyps - an additional explanation for clustering of the solitary stephanocyphistomae. Dormant living tissues within the periderm of the tube were considered resting stages. The results support the concept that coronates in general have the capacity to save all living tissue and transform it to the energy saving sessile stage - the perennial polyp.

Literature records were reviewed to compile a list of species of the marine taxa of Cnidaria Medusozoa recorded for the Brazilian coast. The total number of species of medusozoans so far recorded for Brazil is 373: 347 Hydrozoa, 3 Cubozoa: 23 Scyphozoa.

Checklist dos Cnidaria do Estado de São Paulo, Brasil

Biota Neopropica/Biota Neotropica (2011)

Fábio Lang da Silveira André C. Morandini

Usando como base a Lista dos Cnidaria registrados na costa Brasileira de 1999, os novos registros adicionados no SinBiota/OBIS e examinando as publicações conhecidas no período 2000-2010 temos: 91 novos registros de táxons já conhecidos; 55 novas ocorrências em São Paulo. É sugerido que a falta de especialistas em Anthozoa nos últimos anos em São Paulo deve ter diminuído o conhecimento taxonômico no grupo.
