SATURDAY, 28 MAY 2016recent study by researchers in Australia and the UK investigated the evolutionary and ecological history of the relationship. The paper’s lead author, Dr Jennifer Hoyal Cuthill from Cambridge’s Department of Earth Sciences, said “The extinction risk to the crayfish has been measured, but this is the first time we’ve quantified the risk to the temnocephalans as well – and it looks like this ancient partnership could end with the extinction of both species.”
We’ve all heard about extinction – species lost forever but what happens when another species is entirely dependant on the one that is lost? Co-extinction, that’s what. On the flip side, now that we know what’s at stake, concerted efforts to secure the crayfish’s future will also ensure one for the tentacle flatworm. This is my kind of 2 for 1 offer.
