Currently, little is known about how marine predators search for and find enough food to maintain their body size. It is thought that marine predators could use DMS concentration to locate food sources. In contrast, no association was found between fish biomass and DMS concentration. \"We also plan to explore other attractant chemicals and study their relationship with the behavior of marine predators like whales, seabirds and penguins. Journal information: Communications Biology Kylie Owen et al, Natural dimethyl sulfide gradients would lead marine predators to higher prey biomass,(2021).
