“…Thus A. digitale, which was quantified during the 1990s in this region (Nicholas and Frid 1999), would likely increase with an influx of Arctic water (Raskoff et al 2005), whereas the benthic polyps of scyphomedusae would bloom subject to localized coastal influence. A variety of additional taxon-specific factors and adaptations have been suggested to explain fluctuations of scyphomedusae (e.g., Brodeur et al 1999;Thuesen et al 2005), cubomedusae (Hartwick 1991), hydromedusae (Nicholas and Frid 1999), and even hydroids (Madin et al 1996;Bollens et al 2001).…”

Abstract:The giant cubozoan Morbakka virulenta was collected from the central part of the Seto Inland Sea, western Japan in October 2009, in order to observe its development and polyp formation. Fertilization occurred externally. Demersal fertilized eggs were obtained during the incubation of mature females and males kept at a temperature of ca. 17 to 21°C. From the two-cell stage onwards, fertilized eggs developed into blastulae within 4 h. The development of the blastulae stopped for 21 days after forming blastocysts. This formation of blastocysts is up to now unique within the Cnidaria. The planulae, which developed inside the cysts and lacked larval ocelli, this being characteristic for the Cubozoa, finally metamorphosed into polyps bearing only a single tentacle. The 16-tentacledstage in polyps was reached about three months after this metamorphosis. Budding occurred in eight-tentacled polyps and swimming polyps were released nine days after the commencement of budding. These unique developmental features of M. virulenta may shed additional light on the evolution of life history strategies in the Cnidaria.

“…Within estuarine systems, settlement and growth of polyp colonies often occur in semi‐sheltered, shallow areas (Cargo and Schultz 1966, Purcell and Grover 1990, Purcell 1992, Olesen et al 1994, Breitburg and Burrell 2014, Shahrestani and Bi 2018). The dispersal of medusae from the creeks or semi‐closed coves to the river channel or mainstem is facilitated by downstream tidal or wind‐driven flow (Hartwick 1991, Moriarty et al 2012).…”

Untangling organisms' multi-scale spatial distributions is challenging due to their interactions with environments at multiple spatial and temporal scales. We deployed an Adaptive Resolution Imaging Sonar (ARIS) in a Chesapeake Bay sub-estuary to investigate multi-scale spatial distributions of the bay nettle (Chrysaora chesapeakei) in May-September of 2016 and 2017. Nettles were found to be dispersed in aggregations of multiple individuals. The average density of bay nettles in 2017 was higher than in 2016. Small aggregations (<5 m) were persistent in both years but only contributed <10% of total observed nettles. Large patches (>30 m) contributed~40% of the total observed nettles. Large patches were more common in creek habitat where nettle density was higher. Nettle density was found to hit a peak value once in 2016, while there were two density peaks in 2017. Different aggregation patterns were observed during the second peak period in 2017 in which the number of large patches increased dramatically. Within the surveyed waterscape, the spatial patterns were consistent over time with higher abundance in the source creek than in the river channel, which underscores that C. chesapeakei requires hard substrate in shallow creeks for its benthic polyp stage. Using the ratio between nettles in the creek and near creek mouth as a proxy for dispersal rate, more nettles were transported out of the creek in 2017 than in 2016. The increase in patch size and high dispersion rate in peak periods in 2017 suggests that individuals were moving out of the creek habitat as density increased. Results highlight the complex spatial structure of bay nettles, which has major impacts on density estimates and subsequently affects our understanding of jellyfish population dynamics and long-term trends.
