Researchers have warned for years about coral bleaching due to global warming and rising temperatures in the oceans. But this phenomenon can affect not only corals, but also fish.

In a study published March 16 in the journal Global Change BiologyAustralian researchers highlight a particular bleaching in biodiversity living in the Great Barrier Reef, reports my number. “The reefs of the future may not be the colorful ecosystems we see today,” the study summarizes.

Bright colors as camouflage

Incidents of bleaching coral reefs are increasing with climate change and ocean pollution. However, the increase in temperature affects the acidity of the water and creates stress for biodiversity, causing corals to darken.

However, if the endemic fish of this region are this colorful, it is possible by imitating these corals. Colors are an ornament, a means of communication, but also a camouflage technique that allows them to escape predators in a multicolored environment.

Less colorful fish than before

“Unfortunately, the coral species that can best survive the immediate effects of climate change are unlikely to provide these colorful refuges,” the study authors explain. According to them, if complex, branched and colorful corals become scarce, fish must also become more opaque to better adapt to their habitat.

The study spanned 27 years to observe this phenomenon over the long term. The result: If blacking fish seem to gain some color over time, the number of multicolored fish found in the Great Barrier Reef has decreased significantly since 1998, the first recorded bleaching event.
