Crab populations are crashing. Could losing their sense of smell be one of the important reasons why?

University of Toronto


Thayne Tuason took this shot at

Ocean Shores WA in 2020. He labelled it, "dungeness crab die off..."  and commented, "Some people might contend they were just "molting", but these crabs looked mostly dead to me and not just a bunch of empty shells as would have been the case if it was them naturally shedding their exoskeleton.

    A new U of T Scarborough study finds that climate change is causing a commercially significant marine crab to lose its sense of smell, which could partially explain why their populations are thinning.
