A Large Aerobic Scope and Complex Regulatory Abilities Confer Hypoxia Tolerance in Larval Toadfish Across a Wide Thermal Range

January 06, 2025

This study examines the oxygen demands and tolerance of larval and juvenile toadfish across a range of temperatures.

We found that larval toadfish have a surprisingly wide aerobic scope and can survive severe hypoxia (lack of oxygen) for hours. Comparing their physiological traits with environmental conditions in Florida Bay suggests that larval toadfish have adapted to survive hypoxia across different seasons, shedding light on their remarkable survival strategy.
