Banks Antarctica Ross Sea rich food source emperor penguins
2020/8/14
A new U.S. National Science Foundation-supported study provides some of the most comprehensive evidence to date of the lengths penguins will go for a meal. The results were reported in the journa...
Diet diversity: Hawkfish species coexist on coral reefs thanks to differing food preferences（图）
Diet diversity Hawkfish species coexist coral reefs food preferences
2020/4/17
How can many species of hawkfish coexist in proximity on the same coral reef? The answer may lie in their individual diets.Hawkfish are brightly colored reef fish that live in tropical oceans. Many re...

Blue sharks ocean eddies fast-tracks food
2019/10/21
Blue sharks use large, swirling ocean currents known as eddies to fast-track their way to food in the twilight zone -- a layer of the sea between 200 and 1,000 meters deep, according to new research b...
