6-5-2024 (BANGKOK) A renowned marine expert from Kasetsart University in Bangkok has sounded the alarm over the potential devastating impact of global warming on the population of clownfish, the iconic and beloved species that has captured the hearts of millions worldwide.
Thon Thamrongnawasawat, a respected authority in the field, took to Facebook on Saturday to express his deep concern about the detrimental effects of rising seawater temperatures on sea anemones, a species that shares a symbiotic relationship with clownfish.
In his post, Thon shared alarming photographs depicting the bleaching of anemones, a phenomenon caused by the loss of microscopic algae known as zooxanthellae from the tissues of these marine invertebrates. The images were provided by members of the “Friends of Thon” network, a group dedicated to monitoring and preserving the delicate ecosystems of the ocean.
Thon explained that as seawater temperatures continue to rise due to global warming, the zooxanthellae, which play a crucial role in the survival of anemones and corals, are forced to abandon their hosts in shallow seas where they reside. This exodus of the microscopic algae results in the bleaching phenomenon, leaving the anemones vulnerable and incapable of providing a suitable habitat for their clownfish companions.
According to Thon, the symbiotic relationship between clownfish and anemones is a delicate balance. While the clownfish find protection from predators within the anemone’s tentacles, they reciprocate by keeping the anemone clean and even attracting food sources. However, when anemones succumb to bleaching, the clownfish are left without a safe haven, putting their survival at risk.
Thon warned that without the shelter provided by anemones, clownfish could face a grim fate, with potential population declines, reduced egg laying, and stunted growth. The loss of these iconic marine creatures would not only be a devastating blow to the ecosystem but also a heartbreaking outcome for those who have come to love and admire these vibrant and charismatic fish.
In a call for action, Thon expressed his hope for timely rainfall to alleviate the rising sea temperatures and potentially revive the bleached anemones, restoring the fertile habitats crucial for the survival and propagation of clownfish populations.
