This study highlights the complexity of interactions between corals and their symbiotic partners (Symbiodinium) in shaping their response to thermal stress.

Virtually all studies published to date on symbiont-induced thermal tolerance indicate type D Symbiodinium is the superior symbiont.

However, using a common Indo-Pacific species, we found that corals associating with type C1 Symbiodinium were more thermally robust than those associating with type D.

Our results challenge speculations that associations with type D are universally most robust to thermal stress and emphasize that interactions between both partners may play a significant role in the way corals adapt to warmer oceans.
