Klovnefisken must adapt to, while its habitat is dwindling. But it will get the difficulty, say researchers.
The brightly coloured clownfish are known from, among others, Pixar-the blockbuster movie “Finding Nemo” is highly exposed to climate change.
Fiskeartens special forplantningscyklus is very much dependent on a stable habitat. It shows a new study according to news agency AFP.
And coral reefs, which are crucial for klovnefisken, is threatened by both the warming of the oceans and pollution.
A French research team observed klovnefiskene through ten years in the eastern Papua New Guinea. The team found that the fish are very dependent on a particular way to find a mate.
But because of climate change will klovnefisken need to adapt quickly, and it can be difficult, writes AFP.
the Clownfish can live the most of life in and around the same søanemone, which is an animal in a family Trbet with firefighters.
In a symbiotic relationship attracts klovnefisken other fish to søanemonen, which stuns the fish with poisonous tentacles and eats them.
In each of the anemone keeps a hunklovnefisk to, a sexually active hanklovnefisk as well as several other males who are not sexually active, describes the researchers.
– When the female dies, the male to a female, and the largest of the non-sexually active males to become sexually active, ” says researcher Benoit Poujol from the French CNRS (Le Centre National de la Recherche Scientifique, ed.) to the AFP.
– Klovnefisken do not have the necessary genetic variation that will allow it to adapt its forplantningsmåde to environmental restrictions.
According to media Live Science had klovnefisken in 2016, not have the status as threatened. But several new studies have put a focus on its vulnerable way of life.
A second study showed, according to british The Guardian, in 2017, to clownfish, who lived in the coral reef, which had been subjected to bleaching as a result of vejrfænomenet El Niño, laid fewer viable eggs.
the UN climate panel, the IPCC, estimated last year, with a global warming of 1.5 degrees celsius, at least 70 percent of the coral reefs in the world disappear.
