Gray Whales

This schematic shows the difference in length between a PCFG gray whale born in 2020 vs one born prior to the year 2000. OSU researchers determined that a full-grown PCFG gray whale born in 2020 is expected to reach an adult body length that is 1.65 meters (about 5 feet, 5 inches) shorter than a gray whale born prior to 2000. For PCFG gray whales that grow to be 38-41 feet long at full maturity, that accounts for a loss of more than 13% of their total length.

Pacific coast gray whales have gotten 13% shorter in the past 20-30 years
