Coral Tumors Found: A First for Turbinaria Corals
15 Sep
Summary
- Scientists documented tumor-like skeletal growths in Turbinaria corals.
- Abnormalities were discovered during scuba surveys in Malvan Marine Sanctuary.
- Larger, older coral colonies are more susceptible to these growths.
Scientists from India's National Institute of Oceanography have identified skeletal tissue growth anomalies (STAs) in Turbinaria corals for the first time worldwide. These abnormal, tumor-like growths were documented during scuba surveys conducted in the Malvan Marine Sanctuary along India's west coast. Previously observed in other coral species, this marks the initial scientific report of such abnormalities in Turbinaria corals off the Indian coast.
These bulbous growths, appearing as bleached masses, significantly impair coral function, leading to tissue loss and algae colonization. Researchers observed that larger and older coral colonies were more prone to developing STAs, likely due to prolonged exposure to environmental stressors like pollution and physical damage. The formation of these growths imposes an energy burden, diverting resources from essential functions like reproduction and growth.
The precise triggers for STAs are still under investigation, with potential factors including water pollution, UV radiation, sediment accumulation, and infections. These findings underscore the urgent need for enhanced monitoring and protection of vital coral habitats like the Malvan Marine Sanctuary to safeguard marine ecosystems against escalating environmental pressures.
