First Record of Porpita porpita (Cnidaria: Hydrozoa) from the coral reef ecosystem, Bangladesh

Abstract

 The occurrence of Porpita porpita is reported, for the first time, in the coral island of St. Martin's located in the southeastern coastal region of Bangladesh. P. porpita was found to occur in the lower littoral zone and beach rock pools, together with molluscan species, and collected during the pre-monsoon season when both water temperature (> 30°C) and salinity (> 30‰) tend to reach a maximum. This study recounts some details on the discovery and description of the species, and thus extends the global distribution and range limits of the genus Porpita.

On the occurrence of blue button, Porpita porpita (Cnidaria: Hydrozoa) from Levantine coast of Turkey

“…Presently, the apparent increase of hydrozoan has been notified in various areas of the world (Brotz and Pauly, 2012;Chowdhury et al, 2016). So, a large number of new jellyfish have been reported from the Mediterranean and the Aegean coast of Turkey in recent years as well (Çevik et al, 2006;Turan et al, 2010;Brotz and Pauly, 2012;Gürlek et al, 2013;Çınar et al, 2014;Ergüden et al, 2014;Onmuş et al, 2016;Gülşahin et al, 2016).…”

“…Although there should be more occurrences of P.porpita in Indian Ocean, there are first reports of it from Bangladesh and Pakistan newly (Chowdhury et al, 2016;Gul and Gravili, 2014).…”

“…As a free-floating pleustonic organism, the species is easily carried to shore primarily by water currents and wind (Pandya et al, 2013). Its distribution spread from tropical to sub-tropical waters of the Pacific, Indian and Atlantic Oceans (Chowdhury et al, 2016). For the Mediterranean Sea, the updated occurrence data of the species is reported in Figure 4 (Gravili et al, 2015;Furfaro et al, 2017;Saygin, 2017).…”

First Record of Porpita porpita LINNAEUS, 1758 (Cnidaria, Hydrozoa) on the Syrian Coast of the Eastern Mediterranean Sea

“…P. porpita is a relatively small, dark blue disc-like shaped, a free-floating carnivorous colony of hydrozoan polyps without sail, measuring about 30 mm in diameter, mostly smaller, and live at the surface of the open ocean. They typically move with the winds, sea currents and tides, and usually wash ashore on beaches during windy days ( [19], [20], [21]). P. porpita has nematocysts, whose sting is not powerful for humans, but may cause irritation ( [22], [23]).…”

“…P. porpita has nematocysts, whose sting is not powerful for humans, but may cause irritation ( [22], [23]). P. porpita was found throughout the tropical and sub-tropical Indian, Pacific, and Atlantic oceans ( [16], [20], [18], [23], [21]).…”
