World Manta Day

World Manta Day takes place on 17 September. The Manta Trust, a UK charity, describes it as a global celebration of manta and devil rays and a call to action for their protection. The 2025 theme was The Power of Protection.

These rays face growing threats from international trade, overfishing and habitat loss. The Manta Trust says that fishing for their gill plates and meat remains the main threat.

Their biology makes recovery slow. NOAA Fisheries reports that giant manta rays usually give birth to one pup every two to three years and live at least 45 years. Manta and devil rays are listed under CITES Appendix II, yet the Manta Trust notes that their numbers continue to fall, and it supports moving them to Appendix I, which would ban all commercial international trade.

Giant mantas feed on zooplankton and can reach a disc width of 26 feet.

If you dive or snorkel with mantas, keep your distance, do not touch them, and choose operators that follow local codes of conduct. Each manta has a unique spot pattern on its belly, so photos shared with research groups can help identify individuals.
