Marine Life – The Lionfish
Witnessing a magnificent Lionfish glide through the water with its memorizing fan-like fins provides an experience that stays in one’s memory for a lifetime. The lionfish is without a doubt one of the most graceful and intricate looking fish that you can come across.
Lionfish have several names like zebrafish, firefish, turkeyfish, and more. An adult can grow as large as 18 inches, while juveniles may be as small as 1 inch or less. The lionfish is one of the most venomous fish on the ocean floor. The venom of the lionfish is delivered through up to 18 needle-like dorsal fins. It is purely defensive and relies on camouflage and lightning-fast reflexes to capture prey of mainly shrimp and fish. A sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties, but is rarely fatal. Give lionfish enough space and they pose no threat.
Lionfish are native to many areas from the South Pacific and Indian Oceans, western Australia and Malaysia east to French Polynesia and the United Kingdom’s Pitcairn Islands, north to southern Japan and southern Korea and south to Lord Howe Island off the east coast of Australia and the Kermadec Islands of New Zealand.
Over the recent years Lionfish have been reported far from their native homes in areas where they do not belong like the southeastern United States coast from Florida to North Carolina. I recently dove in Cozumel where lionfish have been somehow introduced to the water and should not be there. The divemasters in Cozumel are actively working to kill the lionfish; during one of my dives a friendly grouper whom the divemasters had been training to eat lionfish followed us through the entire dive like a little puppy begging for a treat. When the divemaster came across a lionfish the grouper watched over his shoulder while he killed it with a spear and then proceeded to feed it to the grouper.
The grouper at first spit it out but after the divemaster introduced it to the groupers mouth again it eventually ate it. Admitedly it was very bittersweet to witness – it was my first lionfish and I was sad to see it killed. Though bittersweet it is a good thing that the divemasters are doing this, because the lionfish have no prey in the area and are killing many fish and the reefs. They need to have a predator in order to keep them from taking over killing all that is left of the marine life in the area.
The lionfish, a beauty but yet an alien invader…

Reef-World launch new toolkit in response to the current global coral bleaching event
The Reef-World Foundation – international coordinator of the UN Environment Programme’s Green Fins initiative – has launched a new coral bleaching toolkit in response to the 4th global coral bleaching event confirmed by the National Oceanic & Atmospheric Administration (NOAA) and International Coral Reef Initiative (ICRI) in April 2024.
The Green Fins Global Coral Bleaching Response Toolkit provides guidance to the marine tourism industry on how they can help manage and monitor the impacts of coral bleaching and get involved in recovery efforts. It features information about coral bleaching, including the causes, impacts and response strategies. The toolkit is compiled from a variety of readily available resources from multiple organizations and initiatives, such as ICRI, Coral Reef Alliance, Reef Check and NOAA, along with Green Fins materials, to ensure it is accessible to everyone. These resources cover methods for reducing local impacts, monitoring the reefs and engaging tourists and local communities.
The El Niño phenomenon has been present since February 2023, which has led to persistently warmer temperatures being experienced around the world and has affected the sea surface temperatures. Coral bleaching has been recorded in all ocean regions ever since. While this event is widespread and serious, there is still hope as bleached corals are not dead corals. Corals can survive bleaching events and thrive if they are given the time to adapt to the changing climate.
“Coral reefs are under a huge amount of stress every day and that reduces their chance of recovery from bleaching events,” said Chloe Harvey, Executive Director at The Reef-World Foundation. “However, this time around the scientists have been watching the data closely, so we’re prepared. We understand what it means and we know what we need to do to respond to it. This global event calls for global action to protect these vital ecosystems for generations to come.”
By equipping the industry with the necessary knowledge and tools, Reef-World hopes to empower these key stakeholders to play a crucial role in preserving the health and resilience of our precious coral reef ecosystems. Reef-World believes that with the right resources, the marine tourism industry can be a driving force in the fight against coral bleaching and contribute significantly to the long-term sustainability of marine environments.
With this momentum, other key players in the industry, such as PADI AWARE Foundation and NOAA, have gotten on board the campaign for more citizen scientists to help out in monitoring coral bleaching. With the toolkit available to all, The Reef-World Foundation is looking forward to more collaborative actions in the industry.
