Oxygen is essential to the survival of the majority of marine organisms.
Since the mid-20th century, scientists have noticed a reduction in oxygen levels in the ocean, and these declines are forecast to continue in the coming decades.
With the levels of dissolved oxygen in open and coastal waters decreasing, there is currently little understanding on how this will impact marine megafauna such as sharks, skates and rays.
Researchers from the Marine Biological Association (MBA)’s Sims Group have published a new paper which examines the many threats these ocean predators could face in severe or prolonged deoxygenation.
