VICTORIA — Crabs that have a normal diet of a type of plankton have been seen munching on methane-filled bacteria off the B.C. coast in what experts say could be their way of adapting to climate change.Researchers with Oceans Networks Canada, a program of the University of Victoria and Oregon State University, discovered the snow crabs using other food sources because their main meal may be disappearing with a warmer climate.
Senior scientist at Oceans Networks Canada and the study’s co-author Fabio De Leo says by collecting these specimens, researchers can learn how a variety of sea-dwelling species are adapting to ongoing changes linked to climate change.He says this shows the crabs’ diet is diverse and includes bacteria that processes methane and they may be able to adapt if their common food source becomes scarce.
