Plankton Diet May Boost Coral Resilience

Quick Summary

• Researchers observed blooms of giant plankton,pyrosomes,along Timor-Leste’s northern coast in Southeast Asia.
• These gelatinous planktons, including Pyrosoma atlanticum, can grow up to 8 inches long and are carried by ocean currents from the Pacific to the Indian Ocean.
• Corals in this region have been seen consuming these pyrosomes using their mesenterial filaments to digest them effectively.
• Feeding on nutrient-rich pyrosomes may enhance coral growth, improve photosynthesis efficiency, and facilitate recovery from bleaching events.
• Timor-Leste’s reefs have largely avoided mass bleaching incidents over the past decade due to cooler waters brought by regional currents.
• The findings suggest a blueprint for coral resilience against climate change.

Indian Opinion Analysis

The finding highlights how natural ecosystems may find unique ways to adapt in the face of climate challenges. For India, which boasts extensive coral reef systems such as those in Lakshadweep, Andaman & nicobar Islands, and Gulf of Mannar-all vulnerable to increasing temperatures-this study opens up new avenues for targeted conservation efforts. Understanding how cross-regional ocean currents support coral biodiversity could help policymakers focus on preserving such critical marine corridors.India’s reliance on fisheries and coastal biodiversity means protecting reefs isn’t just ecological but also economic. Drawing lessons from Timor-Leste’s resilient reefs might aid sustainable approaches for guarding Indian coral ecosystems while adapting them against temperature-induced bleaching events.
