Survived but not safe: Marine heatwave hinders metabolism in two gastropod survivors.

Marine heatwaves (MHWs) are an emerging threat to marine organisms that have increased in frequency and magnitude in the past decade. These extreme heating events can have differential impacts on organisms with some experiencing mortality while others survive. Here, we experimentally exposed two species of subtidal gastropod (Trochus sacellum and Astralium haematragum) to two realistic intensities of MHW to test the ability of different species to physiologically cope with extreme heating events.
