Using prey size measurements from ten Southern Ocean lanternfish species sampled across >10° of latitude, this study shows that higher temperatures were associated with smaller fish and an overall decrease in the size of fish relative to their prey. Ocean warming may therefore alter the diversity and size structuring of trophic interactions, reducing the stability of marine ecosystems.
