HIMB Study Suggests Some Fishes are more Resilient to Climate Change than Previously Thought, but Survival is Limited to Smaller Individuals
Abu Dhabi, UAE, July 1 2024— A team of researchers have uncovered surprising survival tactics by coral reef fish who inhabit the Arabian Gulf, the warmest waters on Earth.
Led by Jacob Johansen, Associate Research Professor at Hawaiʻi Institute of Marine Biology at University of Hawaiʻi at Mānoa, and John Burt, Co-Principal Investigator at The Mubadala Arabian Center for Climate and Environmental Sciences (ACCESS) at NYU Abu Dhabi, the team discovered adaptations in metabolism and swimming abilities that help fish survive the extreme heat of the Arabian Gulf. Surprisingly, these fish did not follow leading theoretical predictions where the maximum size of fishes is expected to reduce due to limitations in metabolic oxygen-supply. Instead, these fish demonstrated an unexpected capacity to maintain sufficient oxygen to fuel performance, even at elevated temperatures.
