A new study suggests that elephant seals can serve as “smart sensors” for monitoring fish populations in the ocean’s twilight ...

Marine biologists at the University of California Santa Cruz have tagged thousands of northern elephant seals with smart sensors.

At the ocean surface you’ll find the sunlight (euphotic) zone, where light is strong enough for photosynthesis. This layer extends to about 200 meters deep, where you’ll find the beginning of the ...

A new study by marine biologists reports that seals can essentially act as 'smart sensors' for monitoring fish populations in the ocean's eerily dim 'twilight zone.' ...

Scientists have a different idea of the twilight zone. To them, it’s an area of the open ocean where most fish live – depths of 650 to 3,200 feet.

The population fluctuations of these marine mammals reveal a connection between the abundance of their prey and biophysical ...
