Recent reports show that the rising temperatures of seas and oceans, driven by climate change, are allowing warm-water fish species such as the whale shark to find a new habitat in the Strait of Gibraltar. This area, traditionally home to cooler water species, is experiencing a shift that resembles the ecosystems of the Caribbean, approximately 6,000 kilometers away. This trend highlights significant ecological changes occurring in our oceans.

The warming trend has been notable along the Andalusian coast, affecting regions from Algeciras to Granada. Local marine environments are transforming, enabling tropical species to thrive, which poses both opportunities and challenges for existing marine life and local fisheries. As the ecosystem shifts, there is a growing concern about the impact on native species and the overall health of marine biodiversity.

This phenomenon, described as the 'tropicalization' of the Mediterranean, raises questions about the long-term implications of climate change on marine habitats. As more species migrate towards warmer waters, researchers warn that this could lead to unforeseen ecological effects, including the potential disruption of food chains and local ecosystems that depend on native fish populations.
