“…It is noteworthy that many of these species may have potential environmental, anthropogenic or socioeconomic interest. For instance, Olindias spp., P. physalis, L. tetraphylla and Chrysaora lactea Eschscholtz, 1829 are well-known stingers (Kanashiro 1985;Resgalla Junior et al 2011;Patry et al 2014;Lecanda et al 2016;Bastos et al 2017;Roveta et al 2019;Santhanam 2020), and most of planktonic cnidarians are commonly considered as bioindicators of different environmental conditions, including anthropic impacts (Nogueira Júnior et al 2022). Moreover, many of these species may have high trophic impacts when abundant.…”

Epipelagic cnidarian fauna in the Western Equatorial Atlantic Ocean off the Amazon River Delta

et al. 2022

We surveyed the epipelagic cnidarian fauna from the Western Equatorial Atlantic Ocean. A characteristic feature in this area is the freshwater discharge of the Amazon River, the largest continental inflow in the world's oceans. We analyzed 87 plankton and 90 neuston samples collected at the neritic and oceanic provinces of the Western Tropical Atlantic under the influence of the Amazon River Plume off the north coast of Brazil. We studied 34,772 organisms corresponding to 7 orders, 31 families, and 93 species. Among them, Forskalia tholoides was a new record to the coast off South America, and 20 taxa were new regional records. Species accumulation curves and diversity estimators did not reach an asymptote and clearly suggested the occurrence of a considerably higher number of species. Sampling in different seasons, with different gears, and including deeper waters certainly will further increase the number of known pelagic cnidarian species in the area. Open ocean had higher diversity than the continental shelf, both for holoplanktonic and some meroplanktonic taxa. This trend can be related to complex circulation and topography. In conclusion, we observed high diversity in the epipelagic cnidarian community. The heterogeneity of habitats in the area is likely the main factor responsible for the high biodiversity, with samples from estuarine, coastal, neritic (with a large reef system), and oceanic waters. The wide salinity range caused by the Amazon River Plume and other oceanographic mesoscale processes such as eddies and opposite currents add further complexity to the environment.

“…Furthermore, annual semi-quantitative abundance was calculated from the monthly datasets using the following equation previously used by [62]: The blue button P. porpita is a fl oating colony of hydroids inhabiting mainly the superfi cial part of the water column as neuston. The species has been found in the Atlantic Ocean, Indo-Pacifi c Ocean and Mediterranean Sea [15,38], including the Adriatic Sea [35,69]. There are only three known records of mass occurrences of this species: stranding of large numbers of individuals along the coast of Odisha (India) during the summer season [70], high abundance (1-2 individuals/m2) along the southeast coast of Bangladesh in March/April 2014 [73], and along the northern coastal region of the Sea of Japan [46].…”

“…Recently, there are more data on the occurrence of this jellyfi sh in the Mediterranean Sea, mainly because of its negative impact on tourism. Indeed, O. mulleri causes mild dermatitis in humans through its stings [69]. It was the third most common sting along the coasts of Salento Peninsula (Italy) [24].…”

In the southern part the Adriatic, gelatinous macrozooplankton fauna is poorly known compared to the other taxa. Therefore, our goal was to collect and systematize all available phenological data and abundances of gelatinous organisms based on scientific surveys from 1996 to 2020 and a ”citizen science“ sighting program in the southern Croatian waters. The inter-annual variability and seasonality of planktonic Cnidaria and Ctenophora were described. A total of 590 reports was received from citizens, which summed up to result in 870 data together with the scientists’ records. In total, 15 species were recorded. Of these, scyphomedusa Pelagia noctiluca accounted for 34 %, followed by ctenophora Cestum veneris (19 %) and the scyphomedusa Cothylorhiza tuberculata (17 %). Mass occurrence was most frequently found in P. noctiluca and then in C. tuberculata and C. veneris. Isolated mass occurrence was recorded for the freshwater hydromedusa Craspedacusta sowerbii, found in Lake Kuti near the mouth of the Neretva River, and for the scyphomedusa Aurelia cf. solida. The three species A. solida, Mnemiopsis leidyi and C. sowerbii are not native to European waters. Considered that alien species are invading the Adriatic Sea and human impact and global warming are increasing, it is crucial to carefully monitor the occurrence of gelatinous zooplankton taxa and to conduct studies focused on deciphering their ecological impact in marine ecosystems. Therefore, our empirical analysis of 25 years of observations provides essential information on the variation of gelatinous zooplankton in the Southern Adriatic region.

“…While there can be a shared pool of nematocyst types within a genus, species can be distinguished by variable patterns in the size and localisation of nematocysts [104]. The nematocyst populations of discrete anatomical regions have been detailed in several sea anemone species [90,[105][106][107] as well as jellyfish [108][109][110][111], hydromedusae [104], tube anemones [112] and corals [113]. Through these studies, it has become apparent that nematocyst densities vary across the body plan ( Figure 4) and that different structures have different proportions of nematocyst types [84,114].…”

Characterising Functional Venom Profiles of Anthozoans and Medusozoans within Their Ecological Context

et al. 2020

This review examines the current state of knowledge regarding toxins from anthozoans (sea anemones, coral, zoanthids, corallimorphs, sea pens and tube anemones). We provide an overview of venom from phylum Cnidaria and review the diversity of venom composition between the two major clades (Medusozoa and Anthozoa). We highlight that the functional and ecological context of venom has implications for the temporal and spatial expression of protein and peptide toxins within class Anthozoa. Understanding the nuances in the regulation of venom arsenals has been made possible by recent advances in analytical technologies that allow characterisation of the spatial distributions of toxins. Furthermore, anthozoans are unique in that ecological roles can be assigned using tissue expression data, thereby circumventing some of the challenges related to pharmacological screening.
