Sunday, February 3, 2019, 1:41 PM – Since 2013 marine scientists have observed a zombie disease spread; among different types of starfish, and new
A study says that the temperatures of the warming sea play a part in mass deaths.

The study, published in Science Advances, analyzes a variety of Starfish starfish species and is exposed to sea star drinking (SSWD), which causes the formation of small and white lesions and then # 39; result in losing members.

Along the Pacific coastlines, from Mexico to Alaska, more than 20 different species of starfish have been affected by the disease. As the disease increases aggravating severe casualties, the members end up from the middle of the starfish and obstruct their reproduction capacity, which contributes to population decline .

The study finds that peak reductions in starfish populations coincide with warm sea surface temperatures, especially when oceanic waves are & quot ;.

The researchers explain that the increasing abnormal temperature has shown to influence the frequency and severity of infectious sea diseases, which has been confirmed in a number of experimental and field studies.

As with the human body, the stars of the sea reach the best possible health at a certain temperature. When these temperatures are higher than the use for long periods, their bodies have a stress that puts them at higher risk of infections that can go on to deaths.

Previous research has suggested that the disease may be associated with a virus (intensity associated with the seabed or SSaDV) that can start wasting in the seabirds, but it was not confirmed plays a part in many of the biggest starfish star.

In deciding exactly the cause of the disease more research will be needed, the results of the study indicate a serious reality for many of the Pacific Ocean sea stars. Since 2013, over 20 species of seabirds have seen a decline in the population
between 80 and 100 percent from Alaska to British Columbia.

Areas that were once intense with bright sea stars are now naked, with the exception of small populations where the disease is common, and the seals of the sea can be seen walking around with their falling bodies, as shown in the video above.

Researchers emphasize that these finds are not isolated observations, but there is a broad, multi-national environmental crisis that confirms that marine ecosystems are facing difficulties.

Science director of the SeaDoc Society at the University of California, Joseph Gaydos, explained that conservators look at ways to protect the species, in
interview with CBS.

"If we all start doing things, we will have some impact. We can only throw our hands," said Gaydos.
