Oregon State University Study Reveals Bat Rays Use Chemical Signals for Warning
Researchers at Oregon State University have discovered that bat rays release a chemical cue when frightened, serving as a warning to other rays, a behavior previously unobserved in cartilaginous fish.

A recent study from Oregon State University has shed light on the anti-predator strategies of bat rays. When these rays are frightened, they emit a chemical cue that warns other nearby rays of potential danger.
This behavior aligns with similar anti-predator strategies observed in bony fish, although it had not been documented in cartilaginous species like bat rays until now.
The findings, published on June 20, 2026, contribute to our understanding of marine biology and the complex interactions within aquatic ecosystems.
