clam-gobbling rays reach Japan!

Warming tied to spread of clam-gobbling ray. A species of ray that is usually found in tropical and subtropical waters has been seen in waters around Japan in recent years and is believed to be responsible for damaging the local shellfish habitat.

The long-headed eagle ray, whose scientific name is Aetobatus flagellum, has been spotted in the Ariake Sea and Seto Inland Sea in western Japan.

Scientists believe that a rise in sea temperature is responsible for the expansion of the creature’s habitat.

While a theory has it that sea temperature rises in the Pacific Ocean are part of long-term temperature fluctuations, many scientists believe that global warming is responsible for the phenomenon.
