"Rare" jellyfish are not so rare – Science Daily


Რდესაც when Rhizostoma luteum The griffith discovered in the early 19th century was only nine samples in the waters of the Gibraltar Strait. Over the years it was so inappropriate that it could not be achieved in the 20th century for the sixth decade. A group of scientists, on the initiative of the citizens, has already confirmed that it is not as difficult as it was before.

In 1827 the French naturalists Jean René Constant Kuo and Joseph Paul Gimard traveled astrolabs with a much more aggressive journey to discover new species of Gibraltar Strait. Describes Rhizostoma luteum (Formerly called Orythialutea) was thankful for the analysis of nine samples. This was the first and last time.

Over the next decade, this jelph has gone unnoticed and there have been no scientific records in the last 60 years. It was not until 2013 when a group of scientists headed by Laura Priuuto (CSIC) of the Institute of Marine Sciences, confirmed the existence of these species through the phylogenetic analysis in Mediterranean waters.

"We believe that every time it seems to be mistakenly identified with other july Rhizostoma pulmo, the Rhizostoma octopus And Catostylus tagi, "As Prieto, another co-author of the study, arguing that this jellyfish factor is more richer than what he thought.

New work, part of future dissertation work by Karen Kinberger and recently published Marine Biodiversity The magazine made some historical and last record Rhizostoma luteum Since 1998, thanks to scientists' observations and citizen initiatives.

The results show more than 150 observations over 17 years, "which shows that these are not rare species that are not after all this," the authors said.

"In addition to this work, we started researching what an unusual species thought was really a good one for many years," explains Priodo. R. The lounge is often in the west of the Iberian Peninsula and in the coastal waters in the south, from the west and north of Africa.

Like others

Jellyfish can reach diameter over 60 cm with some samples; Slightly different weapons and sometimes – but not always – they are very long and go over two meters high.

"Its geographical distribution is very wide: in Portugal and in the Atlanta region of the Atlantic, in further surveys, we could verify that the mother carries her protected descendants until it relieves them in the appropriate environment," the researcher said.

In order to reduce the jelly, Laura Prieto and Karen Kinberger helped citizens who sent historic accounts, photos and videos to the North Atlantic Atlantic Ocean and Alboran Sea. "Posters have been distributed diving and marine clubs and many non-scientific outreach literature such as book diving or marine fauna, are subject to revision," says the Priet.

Scientists contacted many authors of photos, viewed open social networks and photos opened on the open databases that included photos. "Any citizen could send an e-mail on the spot, date and vision photo," notes the article.

For researchers, this type of work enables biodiversity monitoring and method in which the species will respond to climate change in marine ecosystems.
