Pacific Coast Gray Whales Have Shrunk 13% in the Last Two Decades

Oregon State University study reveals significant decline in body length, raising concerns about whale health and ecosystem stability.

Gray whales in the Pacific Coast Feeding Group are now 1.65 meters shorter than those born before 2000.
The reduction in size could impact the whales' reproductive success and energy reserves.
Changes in ocean upwelling and relaxation cycles are linked to the whales' shrinking size.
Researchers are investigating climate change and human activities as potential contributing factors.
The study highlights the role of gray whales as indicators of broader environmental health.
