Summary

Story summary

The Ohio State University study analyzing nearly 3,000 species finds significant diversity in deep-sea fish body shapes driven by habitat.
Pelagic species in open water display a range of forms, while benthic species on the sea floor are more uniform.
Deeper waters promote faster evolution and greater diversity, with pelagic species originating from multiple lineages.
The lack of sunlight in deep waters shapes survival strategies, resulting in less active hunting.
