In a collaborative effort, Marine Megafauna Foundation has teamed up with other organisations to release a scientific publication, Sizing ocean giants, where 25 of the world’s largest ocean species are analyzed to highlight size variations, geographically and historically.
World scientists have teamed up to analyze trends and review what is currently known about 25 of the ocean’s largest marine species. One behalf of her global team, Dr. Andrea Marshall, Director of Marine Megafauna Foundation (MMF), contributed information for the largest batoid, the giant manta ray, drawing on data obtained from the several locations where the MMF’s manta ray projects take place.
The new study in Peer J highlights that while we still have a lot to learn about the largest species in the ocean, the maximum size of some of our largest ocean species has decreased from historical records. The paper notes that the geographic variation and decrease in size of some of these animals is likely attributed to humans. Ten of the twenty-five species analyzed are listed on the IUCN Red List of Threatened Species, including those researched by Marine Megafauna Foundation, such as the giant manta ray, whale shark and leatherback turtle.
“We are privileged to be researching some of the largest fish in the ocean and this study helps illustrate the precarious future of some of the world’s most iconic megafauna species,” said Dr. Marshall.
