The alga Rugulopteryx okamurae, native to the Mediterranean Sea, has been observed to be growing significantly along the coast of Sines, according to various reports. Its presence poses a threat to biodiversity in the region.

Increasing water temperatures and abnormal wave action have been identified as the main causes of this species' growth. These environmental conditions may have contributed to its strong accumulation on several beaches in the Sines municipality.

Scientists explain that the wave action has been uprooting parts of the algae from the seabed and transporting them to the shore, thus worsening the local situation. This dynamic interferes with the ecological balance of the region.

Local authorities and organizations are monitoring the situation, given the concern over the impacts that the presence of this alga may have on marine ecosystems and native species.

The situation continues to be analyzed, and new information regarding the development of Rugulopteryx okamurae is expected as research progresses and environmental conditions evolve.
