This signalled the start of a first-of-its-kind study for these species in Mozambique, with the objectives of identifying primary aggregation sites, understanding their movements and home range and identifying the threats they face in the region.

Two types of tags are being used in the study—acoustic and pop-up archival satellite tags—so that both fine and broad-scale movements can be studied.

Ocean warming is causing declines of coral reefs globally, raising critical questions about the potential for corals to adapt. In the central equatorial Pacific, reefs persisting through recurrent El Niño heatwaves hold further important clues; We have previously reported on Red Sea coral resilience to climate change.
